DMG 3200/3100/3000 – User Manual
1 Introduction
Thank you for purchasing the DMG 3200/3100/3000. This manual describes how to install,
configure, and operate your new equipment. It is written for professional operators of video distribution
systems and assumes a prerequisite level of technical knowledge.
Page 12 (306)
DMG 3200/3100/3000 – User Manual
2 Installation and Safety
2.1 Installation and Safety
The unit is designed to offer operators reliability and flexibility. It consists of a chassis in which a
number of modules can be installed. To cater to specific system requirements, the chassis can be
configured to host functional modules best suited for a given scenario.
Sencore products can be delivered in different chassis variations - 1RU chassis and a 4RU
chassis. The product models DMG 3000 and DMG 3200 represents the 4RU chassis, while the
product models DMG 3100 and DMG 3200 represents 1RU chassis.
2.1.1 The 4RU Chassis
The 4RU chassis consists of a total of 18 slots all of which can host functional modules. Slot
number 0 is dedicated to host the switch module and slot number 17 can only host multi-slot input
modules. Alternatively a second switch module can be placed in slot 17 for some redundancy
configurations. The remaining 16 slots are identical and can be occupied by any of the functional
modules available. A 4RU chassis including a mandatory switch module, power supply
connectors, and module slots is shown in Figure 2.1 and 2.2. Power modules and fan modules
are inserted from the back (figure 2.3 showing the DMG 3200 4RU).
Figure 2.1 – 4RU chassis (DMG 3000) with power connectors, switch module and available
slots.

2.1.1.1 Product models
4RU chassis models: DMG 3000 and DMG 3200
2.1.1.2 Ventilation
The 4RU chassis with Telco mounting has forced air flow from front to back in the chassis,
allowing for multiple units to be stacked above each other with no space in between. However,
adequate space must be provided in front of and behind the unit for effective ventilation. For
Broadcast mounting, air flow will be from back to front.
2.1.1.3 Replacing the power supply module
The 4RU chassis can be installed with one or two power supply modules (DMG 3200 always
comes with two power supply modules). The modules can be exchanged from the rear of the
unit. The chassis delivered with a single power module can be updated by acquiring additional
power module.
If power is lost in one of the Power supplies, the other can feed the entire chassis. It is
recommended to connect each input power at different circuits.

This DMG 3200 has forced air flow from front to back allowing for multiple units to be stacked
above each other with no space in between. However, adequate space must be provided in
front of and behind the unit for effective ventilation.
The DMG 3200 has 6 fans in front. Fan speed is temperature controlled. If one fan fails,
remaining fans will increase speed to compensate. The whole Fan module, containing all 6
fans, can be hot swapped. If, during fan module replacement, the temperature on the inserted
modules exceeds a certain critical temperature, the unit will shut down, to prevent damage of
the inserted modules.
2.1.2.2 Replacing the power supply module
This 1RU chassis can be installed with one or two hot swappable power supply modules. The
modules can be exchanged from the rear of the unit. The chassis delivered with a single power
module can be updated by acquiring additional power module.
If power is lost in one of the Power supplies, the other can feed the entire chassis. It is
recommended to connect each input power at different circuits.

Each input module available in the unit has some common analysis features; they all support
manual definition of input PSI. The coming sections will describe these common features
followed by details on how each input module can be configured.
5.2 Input Analysis
For each input module the unit provides detailed MPEG/DVB/ATSC transport stream analysis
for all available input streams. The following information is provided by the input analysis
engine:
•
Port specific status
•
PSI/SI analysis of all input services
Page 45 (306)
DMG 3200/3100/3000 – User Manual
•
PID display – listing all input PIDs for each input, with implicit highlighting of CC errors,
PCR flag and scrambling bits (odd/even)
This information is accessible by expanding the Inputs view in the Navigation Pane. The
following example (Figure 5.2) is based on a DVB-S/S2 input module, but the same applies to
all input modules.
Figure 5.2- Example of DVB-S/S2 Inputs
5.2.1 Input Port Analysis
Within the Inputs node, it is possible to access lower level information, e.g. port specific
information. To obtain port specific information for input modules with demodulators, click on the
port letter in the Input column.
Figure 5.3 - DVB-S/S2 Port Detailed View
For more details on actual parameters, refer to the configuration section for the respective input
type in this chapter.
Page 46 (306)
DMG 3200/3100/3000 – User Manual
5.2.2 Input Service Filtering and Analysis
It is possible to apply filters on information displayed in the GUI. Clicking on view in the Service
column for a selected multicast, results in only services associated with this multicast being
displayed. Clicking on one of the listed services will display more detailed information about the
different PIDs like PMT, PCR, video, audio, etc.
Click on view in the PID column for ASI inputs will display only PIDs associated with the
selected input. Simply choose any PID to obtain more detailed information.
To access detailed PSI/SI analysis of the input services, click the respective service in the lower
pane. The detailed analysis result will appear next to it, on the right.
Figure 5.4 - Detailed PSI/SI Analysis of Input Services
The Audio language descriptor is decoded. In Figure 5.4, the audio is listed as dan, ie Danish.
However, if no language descriptor is present the unit will auto-generate a descriptor for internal
usage and they will be named A01, A02, etc.
Details of the PSI/SI analysis are not 100% DVB compliant, but it does include
the most commonly used tables and descriptors.
Page 47 (306)
DMG 3200/3100/3000 – User Manual
5.2.3 Input PID Analysis
The PID view lists all PIDs detected for a given port. This list is accessible via the PIDs column
in the top pane.
Figure 5.5 - PID Scrambled with Even Control Word
Figure 5.6 - PID Scrambled with Odd Control Word
For an input containing scrambled services the color of the scrambled PIDs will toggle between
Blue and Red as the ODD/EVEN bit toggles.
In Figure 5.5 and Figure 5.6 we can for example see that PID 521:
•
is scrambled as it is colored,
•
contains PCR as it is bold, and
Page 48 (306)
DMG 3200/3100/3000 – User Manual
•
no CC errors have occurred since none of the PID numbers are inverted in color.
It is possible to reset the CC error counters. This reset is a global operation for all inputs and is
done with the Reset CC button in the Inputs node.
To obtain PID specific details, simply click on view in the PID column.
Figure 5.7 - Selecting PID 20
Selecting PID 20 (Figure 5.7), we see that it is a TDT PID. Also, its bitrate and number of CC
errors are presented.
Selecting PID 550 gives a slightly different info as it is a video PID:

5.3 Manual PSI
To manually define input PSI select Inputs  Manual PSI from the Navigation Pane.
In case the input PSI information is not available, a predefinition of the PSI is necessary in order
to configure a service that is occasionally available. This could be used, for instance, to
predefine some services for dynamic VOD usage.
Figure 5.9 - Manually define Input PSI
In the Manual PSI node, click Add Service and enter the appropriate values matching the
incoming stream. The following information is displayed:
Service Id
Service ID for the manual service

DMG 3200/3100/3000 – User Manual
The PMT PID may be defined with any value from 32 to 8190, but ensure that
it is unique in an MPTS configuration scenario. Also, if this input is part of an
outgoing digital stream, the PMT PID here is the PID value that will be
assigned for the outgoing PMT.
When an input service is defined the following tables are generated:
•
•
PAT
PMT
All other table analysis is cancelled for this input port. The result is listed in the GUI (see Figure
5.10).
Figure 5.10 - Table Analysis when an Input Service is defined
This entry may be edited or deleted later using the corresponding icons on the left.
5.3.1 MPTS Support
If multiple services are defined for one input, they effectively represent a MPTS.
To check that the manually defined input has entered the system correctly, select the Inputs
node and ensure that the service information is present. In the example below (Figure 5.11)
Service number 30 (under the Services panel) is represented with PSI even though the input
has not yet been added to the system.
Page 51 (306)
DMG 3200/3100/3000 – User Manual
Figure 5.11 - Verifying manually defined Inputs
If manual PSI is defined for an input port, all incoming services must be defined.
It is not possible to define only one service manually and use the incoming PSI
to represent the rest.
5.3.2 PSI Modifications of input services
This PSI modification feature allows the user to modify existing incoming PSI, keeping
the other PSI information intact. The feature is currently implemented to solve two
specific scenarios.
• Add signaling to incoming “DVB Subtitling” and “EBU teletext” components in PMT.
Other component types can also be added but without any descriptors only.
• Change audio language descriptor of an incoming audio component.
5.3.3 Defining a component type for an incoming PID.

Burst Mode – All TS data bytes are sent without any idle symbols in
between
Spread Mode – The SI specification requires at least one idle byte
between each data byte, and each packet start indicator (0x47) is
preceded with at least two idle bytes. The ASI output stream in Spread
Mode guarantees that each data byte is preceded with two idle
symbols. This effectively reduces the maximum data rate to 1/3 of the
maximum ASI output rate, i.e. (213/3) Mbps. If higher rates are required,
use Burst Mode.

5.4.5.1 Setup of IPv6 input
The Switch+IP input module supports IPv6 multicast and unicast inputs. When using standard
IPv6 address syntax (128 bits, ‘:’ instead of ‘.’), the GUI will interpret the address as an IPv6
address.
The VLAN setup is independent on the choice of IPv4 or IPv6.
Source IP address has to match the IP format used for the destination IP address.
5.4.5.2 Modification of input
The defined inputs may be modified to use another IP address. The new IP address may
be chosen freely between IPv4 and IPv6 addresses.

5.4.6 Seamless IP Input
The Seamless IP input module allows two input interfaces to be connected to different
network sources, but for the system, this is a single module. The same multicasts are
subscribed to on both interfaces. These multicasts must come from the same source.
All function and status normally associated with IP input cards are present for the logical
module. In addition data rate, sequence errors, and relative delay for each stream are
reported for every input.
Moreover, alarms related to the network interface and stream alarms (e.g. “No bitrate”)
appear as warnings if they occur only on a single interface. “Link down on interface A or B”
is a major alarm. If alarms appear on both interfaces, they will act as for normal IP input
cards, and be a single alarm with the same alarm ID as used on other IP input cards.
The following information is displayed in status parameters for Seamless IP Input configuration:
Slot
Slot position in the chassis

With the Seamless IP Input module, it is possible to configure two non-synchronized multicasts.
In this mode it is required to enable the ‘Filter input synchronization’ option for the port in order
to filter the normally present alarm.
In this mode, the behavior differs from the Seamless IP mode in that the current source will
switch if there is a 100ms with 0 bitrate on the input multicast.
More details on this can be found in Chapter 12.1.5.
5.4.7 Dual IP Input
The Dual IP input module allows two individual input interfaces to be connected to network
sources, but for the system, this is exactly as two IP input cards. The input streams can be
either SPTS (VBR or CBR mode) or MPTS. to configure the module.
All function and status normally associated with IP input cards are present for the module but
the total Input Bitrate for both IP ports cannot exceed 850 Mbps or 250 services, ie the limit is
shared between the two ports.
An alarm (“Back-plane bitrate exceeded. Packet dropped.”) will be raised when the 850Mbps
backplane limitation is exceeded.

6.1 Descrambling – Common Interface Module
The unit is capable of descrambling a number of incoming services with the installation of a
descrambler module. The descrambler module comes with two Common Interface slots and
can therefore host two Conditional Access Modules (CAM’s). Each Common Interface slot
supports the descrambling of one or more services depending on the CAM module used.
6.1.1 Descrambling a Service
To descramble a service first insert the CAM into an available Common Interface slot, then
insert your Smart Card into the CAM.
To assign the Common Interface slot to a service to be descrambled, double click on that
service and within the Outputs page to display the Service Properties dialog (Figure 6.2).
Figure 6.2 - CAM Configuration within the Service Properties Dialog
6.1.2 Transporting a Descrambled Service to Multiple Output Modules/Ports
A descrambled service may be sent to up to four individual outputs. In other words, if the unit is
configured with an IP output module and a QAM output module, then the descrambler module
will be able to copy the descrambled service and send it to both the IP output and QAM output
destinations. Alternatively, the same service can be sent to different ports on the same output
module.
When an input service is configured to be sent to different outputs, the configuration is
automatically performed by the system – as long as the same descrambler is selected. This
copy function is based on per service, i.e. if a Smart Card is able to descramble up to 10
services, then the maximum number of output streams from the descrambler will be 40 (10 x
4).
6.1.3 CAM Configuration
The CAM configuration page below (accessible by selecting Conditional Access  CAM in
the Navigation Pane) displays the following:

Page 95 (306)
DMG 3200/3100/3000 – User Manual
Auto Reset
Automatic CAM Reset – enables the CAM to reset if there are failures in
the descrambling process. This helps the CAM to recover automatically
without requiring the user to reset manually. Auto Reset provides the
following options:
Off – automatic reset is disabled; the CAM can be reset manually.
One – if one or more services have descrambling failures, the CAM will
reset.
Majority – if more than half the services configured to be descrambled in
the CAM fail, the CAM will reset.
All – in this mode, the CAM will simply reset if all services configured in
the CAM fail to be descrambled.
Man Reset
Manual CAM Reset – sometimes resetting the CAM Module is
necessary, e.g. if the CAM is not responding. Click reset to power
recycle the CAM module.
MAX TS rate
[Mbps]
Maximum Transport Stream Range can be used if the rate of the
transponder exceeds the default CAM input rate. The user can choose
one of three values:
•
•
•
43 Mbps
58 Mbps
68 Mbps
The default value is 43; however, not all CAMs support these rates.
6.1.4 Alt CAM Mode
In a normal configuration, when an input stream is sent to the CAM, only a selection of PIDs
that comprise the services being descrambled are actually transmitted, together with CArelated PIDs listed in the PSI.
In Alt CAM Mode, the entire input stream is sent to the CAM without PID filtering. This feature
can be useful in the following scenarios:
Some CA systems do not list all the required PIDs in the PSI. Often this will involve the EMM
PIDs, resulting in problems keeping the subscription updated over time. Alt CAM Mode can
prevent this problem.
Sending all the PIDs changes the packet timing of data streaming into the CAM to more
closely resemble that of the input. Testing has shown that very few CAMs require this to work
reliably over time.
Not filtering PIDs sent to the CAM simplifies the input card configuration due to all input PIDs
being sent. This may slightly improve response time on service changes. The effect may be
marginal, but it could be of value, especially for inputs where most of the services are
descrambled in the same CAM anyway.
The drawback of Alt CAM Mode is increased bandwidth usage from the input card(s) into the
system. In most systems, this is not a significant limitation; however, it should be taken into
consideration for large systems.
Page 96 (306)
DMG 3200/3100/3000 – User Manual
It is generally advised to disable Alt CAM Mode as this creates a higher bandwidth
requirement in the unit.
We recommend you enable this option if you have problems with:
o
descrambling a service
o
keeping the subscription updated reliability
6.1.5 CAM Interface
Each CAM Module has its own menu structure defined by its manufacturer to access module
information, e.g. subscription status and to insert configuration data, e.g. a new PIN Code,
maturity rate, and a key to descramble a service.
The CAM Interface feature allows operators to access and interact with these menus
easily via the web GUI. By clicking on Open under the CAM Interface column, a pop-up
box appears over the CAM Configuration page. This is the CAM Interface dialog.
6.1.6 Navigation
Based on Figure 6.1, the standard CAM Interface provides two buttons at the bottom and
a list of clickable menu options.
•
•
•
The Back/Exit button returns to the previous menu
If the Back/Exit button is pressed on a top-level menu, the same menu screen
will be displayed
The Close button stops interaction with the CAM Module, closes the CAM
Interface dialog, and displays the CAM Configuration page
Figure 6.5 - Example of a Menu from Conax
It is possible that the dialog above varies depending on the CAM manufacturer. Menus
that do not allow user interaction are called Lists. Since Lists are bottom-level menu
items, possible operations are either to go back to the previous menu or close the CAM
Interface.
Page 97 (306)
DMG 3200/3100/3000 – User Manual
Figure 6.6 - Example of List from CryptoWorks
Another type of dialog is the Enquiry dialog (Figure 6.7). This dialog is displayed when
the CAM Module requires user input such as a PIN code. The CAM defines the maximum
length of the input data and whether actual characters are displayed as the user types.
Figure 6.7 - Example of Enquiry
6.1.6.1 Multiple Users and CAM access
The CAM Interface supports multiple users but not multiple sessions. This means that it
is possible to access the CAM Interface of the same CAM Module from different
computers or browsers simultaneously, but users cannot be on different levels of the
menu. For this reason the CAM Interface is refreshed every 10 seconds to request the
current valid menu screen.
Due to this synchronization scheme the menu screen will change for all current users
even if just one of them interacts with the CAM Interface dialog.
Multiple users interacting with a single CAM Module can lead to synchronization errors.
For instance, when one user tries to access a menu that has not been refreshed after
another user has interacted with it, a synchronization error will occur. This will display a
Status error. This and other errors are handled by the CAM Interface to provide safe
and consistent interaction.
Page 98 (306)
DMG 3200/3100/3000 – User Manual
6.1.7 Error Handling
When a situation results in an error and does not permit proper communication with the
CAM Module, an error message will be displayed. There are different conditions that can
lead to errors. Table 1 lists the possible error messages and their descriptions.
Error Message
Description
Error: No session.
Refresh to recover
communication
The user is trying to answer a menu or enquiry and the session has
been closed.
Error: Session ID.
Refresh to recover
communication.
The user is trying to access a session that is no longer available.
Error: Status. Refresh
to recover
communication.
The status count value received from GUI is not the same as the one
in the CAM Interface. This means that the GUI could be in another
level of the menu which can lead to a non desired operation.
Error: Invalid message
format.
The message parsing process is not successful.
Error: CAM No
response. Refresh to
recover
communication.
Within a specified timeout, the CAM Interface failed to respond.
No CAM/PC Card in
slot.
There is no CAM Card in the slot.
CAM not identified, or
identified as non-CAM.
The PC Card is not identified, or identified as non-CAM.
Table 2 - Error Messages and their Descriptions
When an error message is displayed, the Back/Exit button is replaced by Refresh. The
operator can either close the CAM Interface, or try to Refresh the session. If a
synchronization error occurs, Refresh is the ideal solution. Otherwise, the operator can
wait for the CAM Interface to request a Refresh automatically.

6.2 Bulk Descrambling
Sencore’s bulk descrambler is able to descramble up to 250 services per card. Actual
descrambling is performed in firmware while extraction of the Control Word from the ECMs is
done by integrated soft clients provided by the CA vendors. The bulk descrambler runs on a
dedicated module, providing an external Ethernet port used for the communication between the
soft client and the CA server for exchange of access criteria.
The maximum number of ECMs that can be descrambled depends on the processing power
requirement of the CA client.
Currently the descrambler algorithms supported are: DVB-CSA or AES-ECB; but not both
simultaneously.
Below are the CA systems integrated with the bulk descrambler module:
CA System
Number of Services Supported
BISS
250 services
Latens
250 services
Verimatrix
250 services
Preparing the bulk descrambler module to descramble services requires some initial
configuration to establish a link to the CA vendor’s server. To be able to view the GUI and enter
necessary parameters, the correct licenses must be installed as the bulk descrambler
functionality is licensed together with the number of services.

6.2.2 BISS Scrambling and Descrambling
6.2.2.1 Key Handling
The unit supports BISS scrambling and descrambling (Mode 1 and Mode E), which is the
simplest form of fixed key scrambling available. The scrambling solution is based on the
standard scrambler card, while the descrambling is based on the bulk descrambler card.
BISS descrambling can also be done via a CAM based system where the
key is inserted using the CAM interface. Detailed explanation on BISS
descrambling with CAM systems is beyond the scope of this manual.
The key handling procedure is identical for both scrambling and descrambling. A key can be
defined and associated with a name, which is the reference used for the stream’s configuration.
Figure 6.10 – Creating a BISS Mode 1 Key
The figure above illustrates a GUI with one existing key named test. The “test” key may be used
both for descrambling and scrambling.

In BISS Mode E the key (Session Word) is protected by encrypting it using a key ID. An
encrypted key is generated by selecting DCB CSA BISS-E as key type, and using the Encode
mode, and supplying the key ID and key. The resulting encrypted key is displayed to the user in
a popup when the key is added, but is not available to the user later in time. The same
procedure is used in order to retrieve a clear key from an encrypted key and key ID by selecting
the Decode mode.

6.2.3 SIM bulk Descrambler
The SIM Bulk Descrambler Module has the ability to add up to 16 SIM form smart cards, which
are used in conjunction with a supported CA system in order to descramble services. These
SIM cards are able to be loaded on both the front of the module (ports A – H), and on the
module itself (ports I – P). In order to access the slots on the module, this must be removed
from the chassis.

6.3 Scrambling
This section provides a brief overview on how scrambling is performed within the unit. It
introduces the different components required and their purpose and explains how to setup the
scrambler card to establish ECM and EMM channels as well as their actual streams.
For information on how to conduct scrambling, add an EMM to an output transport stream, etc.
refer to Chapter 8.3.
The scrambler module is composed of two components:
•
SCS – a software component responsible for managing the interfaces used by external
ECMG, EMMI, and EIS services.
•
SCR – a hardware component responsible for encryption (DVB-CSA or AES) of the
services.
The functional diagram below shows these components and their relations with the rest of the
system.
Figure 6.17- Scrambler Module Architecture
The SCS module is the master of the scrambling system. It is aware of the ECMG and the
scrambler module. Upon configuration, the SCS card generates a CW, sends it to the ECMG,
which returns the ECM. The SCS then sends the CW to the hardware component scrambling
the live content and transfers the ECM to the correct output card for playout.
Before it is possible to define an output stream with the scrambling properties it is necessary to
define the ECM generator, as the SCS needs to know where to contact the encryption system.
Next step is to define an ECM. The ECM definition associates a CW id and access criteria. The
output can now be defined and scrambled. When configuring the output to be scrambled the
ECM selection list implicitly represents the CW and access criteria while the scrambler indicates
the scrambler card.
Page 109 (306)
DMG 3200/3100/3000 – User Manual
6.3.1 Scrambler Module Configuration
The scrambler module runs both the SCS functionality and the scrambler functionality on one
single card. The Scrambler supports both the DVB-CSA and AES scrambling algorithms – but
only one at a time.
The scrambler card supports up to 250 scrambled services, with a maximum total bitrate of
850Mbps.
An overview of the scramblers present in the unit is available in the Conditional Access node
in the Navigation Tree.
Figure 6.18- Scramblers Overview
This configuration page gives a general overview of how many ECMs and EMMs have been
configured as well as providing a dialog to select which scrambling algorithm to run on the card
(available algorithms depend on the licenses and SW version installed). The options provided
here are based on the information reported by the scrambler card during startup.
6.3.1.1 Configurable crypto period on the scrambler
It is possible to configure a user definable minimum crypto period (CP) per scrambler card,
under Conditional Access → Scrambling (Figure 6.18). The minimum crypto period default is
10 seconds, which is the minimum crypto period supported, but can be set as high as 6553
seconds.
If the nominal CP duration is changed as a consequence of a user changing the minimum CP,
the change takes effect the next CP. Thus, the current CP is not interrupted (neither shortened
nor lengthened in time).
6.3.1.2 Selective Scrambling/Partial Scrambling
The scrambler card supports both selective and partial scrambling, implying that parts of the
content are sent in clear. Selection is done per service and is enabled during the configuration
of the output stream. Selective scrambling is only available for selected CA systems and
requires a license.
6.3.1.3 Configuring an ECM Generator Channel
A connection to an ECM generator is defined in the ECMG node located under the Conditional
Access  SCS node in the Navigation Tree. The connection to an ECMG establishes a
channel over which ECMs will be sent.

It is possible to have several ECMG connections simultaneously but the CAS ID
has to be uniquely defined. If the same CAS ID is used, a real SimulCrypt will
not work as the CA Descriptor in the PMT will be identical for both ECMs. In this
case, private data must be used by STBs to distinguish ECMs.

• IP: 127.0.0.1
• Port: 5555
• CAS ID: 19178
The ECMG will accept one channel only; up to 250 ECM streams are supported. When adding
an ECM, the Access Criteria field may be left empty. However, it is possible to enter a fixed 8byte (16 HEX characters) user specified scrambling key in the Access Criteria field.
6.3.1.4 Configuring an ECM Stream

ECMs as long as they are connected to different ECMGs.
At this point, the ECM stream is defined and the CA system as well as the SCS
module can begin to exchange CW and ECMs. However, the ECM is still not
associated to any output. Refer to the Output Configuration chapter for details on
how to associate ECMs to outputs.

EMM/PD Bandwidth
During the EMM/PD stream configuration the SCS and the EMM/PD generator will negotiate
the maximum bandwidth allowed for a given stream. This bandwidth has a default value of
100kbits/s and can be also set explicitly from the GUI. The maximum total bandwidth
available per card is 3 Mbits/s for these streams.
In the case where the CA system is transmitting more data than the SCS card can handle, the
CA system will indirectly be notified as the flow control mechanism in the TCP stack will notify
the transmitter; hence the CA system can take appropriate measures to avoid overflow.

The scrambling solution supports four CA systems simultaneously. No particular configuration is
required for this. Simply define the appropriate ECMGs, ECMs, EMMGs and EMM connections
required. The system to be used for actual scrambling is defined as part of the output
configuration process.
When configuring services that are to contain information for multiple CA systems, the following
must be done:
•
•
•
The corresponding ECMs for each service / CA system must have identical SCG ID values
All ECMs must be assigned to the service
If applicable, valid EMMs must be added to the output for each CA system
6.3.1.8 Configuring an EIS service Channel
The Event Information Scheduling (EIS) interface is a scheduling interface for associating
ECMs to outputs. The configuration of the EIS is similar to setting up an ECMG/EMMG
connection.
The EIS interface provides the following functions.
•
•
•
Create a new ECM
Modify an ECM’s access criteria
Remove an existing ECM
Control scrambling of an output service. The output triplet (Net ID, TS ID, and SID) is used as
the output service identifier.
As the EIS is not able to create the ECMG channel configuration, this needs to be done from
the web GUI before the EIS can be used.
Based on the DVB Simulcrypt standard, only one EIS is permitted per chassis.
To establish a connection to an EIS service, go to Scrambler  SCS  EIS node in the
Navigation Tree, enter appropriate values and click Add.

7 Digital Output Configuration
The Sencore platform can be used to host a number of different output modules. Select
Outputs from the Navigation Pane to view all available output modules along with key
information on the current configuration for each output module. When expanded, this menu
also provides a list of the output cards, including type and installed slot.
Page 120 (306)
DMG 3200/3100/3000 – User Manual
Figure 7.1 - Outputs View
The following information is available from the Outputs view:
Slot
Slot position in the chassis
Type
Type of output module / output port
Services
Number of services assigned to the output module
Output Rate [Mbps]
Total data rate of all configured services - the rate shown includes all
overhead data such as IP headers.
Creating an output transport stream is done via the Outputs view present for each output
module. Before an output can be created, the input module(s) must be configured correctly
such that the list of input services is present.
The unit supports two types of output streams: Multiple Program Transport Stream (MPTS) and
Single Program Transport Stream (SPTS). MPTS is available for all MPEG output modules
while SPTS is only available for IP output modules in addition to MPTS.
MPTSs are always Constant Bit Rate (CBR) streams. By default SPTSs are Variable Bit Rate
(VBR), i.e. the same as the input source, but can be configured to be CBR.
7.1 Input Stream Selection
When you select an output module, you will be presented with a list of Inputs. This will consist of
ports (for MPTS inputs) or services (IP SPTS inputs). In order to expand the services in an
MPTS input, you can click the
Page 121 (306)
symbol. In order to output a service from the available
DMG 3200/3100/3000 – User Manual
input services, you only need to drag a service from the Inputs panel and drop it on the Output
panel (Figure 8.2)
•
To add a service to an MPTS, drop it on the MPTS symbol
MPTS outputs as well as QAM/COFDM/ASI/etc outputs.
•
To add an IP SPTS to an IP output module, drop the service anywhere in the empty
space on the Output panel.
•
To add a Transparent output drag and drop the input port to an empty space on the
Output panel (IP output) or the output MPTS (other modules).
. This applies to IP
To toggle transmission of an output stream on or off, use the checkboxes on the left of that
particular stream to enable or disable it.
Figure 7.2 - Dragging and Dropping a Service
Once the output is configured, the system will automatically generate PSI/SI as well as add the
service related PIDs to the output (as configured in Outputs  PSI). For more information on
PSI/SI configuration, refer to Sections 7.3.4.
If you are unable to drag and drop an input service to an output, there could be a
conflict in your output setup, most likely due to a duplicate ServiceID/Program
Number.
For example, if you already have an output service with ServiceID 100, and you
attempt to drag and drop an input service, with ServiceID 100 – the system will
assume that you are trying to create two output services with the same ID. To get
around this, first remap the output service ID for the existing one. Then, add the new
service.
This is only relevant when adding the same ServiceID to an MPTS.
Page 122 (306)
DMG 3200/3100/3000 – User Manual
7.2 Auto Service Modes
The Auto-Service modes are available to automate the process of adding services to the
output. I.e., instead of manually selecting a service from the input, the user instructs the system
to add services from the input automatically.
Two implementations of the auto-service exist:
• Auto-First Service
• Auto-All Services
These modes are available for each input port when expanded, ie:
Figure 7.3 – Auto Service modes
These “services” can be added to the output in the same way as regular services, and can be
used in the following ways:
Auto-First Service will map the first available service in the input port. This feature is intended
for VOD, where the source never will contain more than one service. In this mode the output
service can be changed and edited like any other output service. I.e the service name can be
changed; the component/PID mapping can be specified etc.
Auto-All Services will map all incoming services for the input port to an output. Here it is not
possible to do any service editing at all. The service dialogs will be replaced with another dialog
to block selected services.
7.2.1 Configuring an output with Auto All Services
The Auto All Services configuration is done via drag-and-drop of the source “Auto All Services”
to the output. The “Auto All Services” is then enabled for the given source.
Page 123 (306)
DMG 3200/3100/3000 – User Manual
With an “Auto All Services” configured the system will automatically add all these input port
services to the output.
Note: It is not possible to add more than one “Auto All Services” per output.
Figure 7.4 – Auto All Services output configuration
It is possible to filter one or more services to be automatically removed by specifying the
incoming service ID in the blocking list. This is available on the edit dialog of the output “autoservice” and can be accessed by double clicking on this.
Figure 7.5 – Stopping a selected service
By removing the “Auto All Services” node all the services from that input will be removed.
In conjunction with an ‘Auto All’ service, it is possible to add additional local or other programs in
the normal way i.e. drag and drop to the MPTS node.
Service ID clashes are not automatically handled when using a combination of ‘Auto
All’ and additional services.

DMG 3200/3100/3000 – User Manual
7.3 Transport Stream Generation
To begin generating MPTS outputs, we set the Transport related parameters via the Edit
2
Multiplex dialog, accessible by double clicking on the MPTS.
The procedure for adding services/multiplexes varies according to the type of module.
For non-IP modules, services are added to the output stream by dragging and dropping, as
illustrated in Figure 8.2. This method is possible because entries in the Output panel already
exist for these modules, corresponding to their physical ports. The Default Stream Properties
panel for these modules is used for adding new services.
For IP modules, output multiplexes can be added by entering appropriate values in the Default
Stream Properties panel and clicking Add MPTS (if MPTS license installed).
Figure 8.7 and Figure 8.8 below show the different Default Stream Properties panels for these
modules.
Figure 8.6 - Default Stream Properties for IP Modules
Figure 7.7 - Default Stream Properties for all other Modules
When creating an SPTS, the Default Stream Properties will be used and the IP address will
be incremented.
To add a unicast service, enter the destination port together with the destination IP
address.
The following fields are available for Default Stream Properties; these fields vary depending
on the module type:
2 For ASI, COFDM, and QAM modules, “Multiplex” is replaced with the module type.

The maximum number of channels through the output module is 250.
Manually mapped PIDs on outgoing Transport Streams are not checked for
PID conflicts. These PIDs are not signaled in the generated PSI/SI table.
Importing PIDs is treated as a service by the system consequently reducing the
number of services handled by the module with one.

7.3.2 Port Settings
The Port Settings tab is module specific and differs accordingly. Please see 8.4 for the specific
output module settings.
7.3.3 EMM
The EMM tab is only present if one or more scrambler modules are present in the unit, or if
using IP SPTS.
This tab makes it possible to add EMM streams inserted by the CA server via the unit’s
scrambling module by selecting the desired EMM(s) from Available EMMs and clicking on the
appropriate arrow to move it to Selected EMMs.

Passthrough option as shown in the figure below.
Figure 7.17- Passthrough Option for EMMs in SPTS
Passthrough
Page 131 (306)
EMM Passthrough enables an incoming service to be transmitted with its
original CA including EMM and CAT without being descrambled in the
unit, so that receivers further down the chain can carry out the
descrambling process instead.
DMG 3200/3100/3000 – User Manual
When passthrough is enabled, the internal generation of the CAT table is
automatically disabled.
7.3.4 HbbTV Apps
On the HbbTV Apps tab, one or more HbbTV applications can be configured. These

The PSI tab allows the base values defined in the Outputs->PSI node to be overwritten for
each specific output stream. The list in the table reflects the currently selected mode: MPEG,
DVB, ATSC or Default.
Figure 7.19- PSI Tab for IP Modules
To modify any of the base values (default values), disable Default and set the values as
needed.
If the change in base value is applicable to all outputs, it is simpler and neater to change it from
the PSI node in the Navigation Pane, where the base values are configured. A change in the
base value from this page will automatically propagate to all outputs applicable.
The PSI tab is identical for both MPTS and SPTS.
7.3.5.1 PSI configuration for services in an MPTS
Individual services within an MPTS have a PSI tab that allows for the PMT’s Mode and Playout
Interval to be modified.

page in the Navigation Pane.
DMG 3200/3100/3000 – User Manual
Transcoder
If there is a transcoder module available in the unit, this will allow you to
allocate the service to an available transcoder port.
For each outgoing service, it is possible to manually set the signaling of EIT Present Following
or Schedule in the SDT:
Present
Following
Schedule
Choose one of the following:
•
Auto – If the EIT table configuration on the PSI page is set to
Play or Pass, then the SDT flag is set to 1. Otherwise, it is set
to 0.
•
Present – the EIT present/following flag in the SDT is set to 1
•
Not Present – the EIT present/following flag in the SDT is set
to 0
Choose one of the following:
•
Auto – If the EIT table configuration on the PSI page is set to
Play or Pass, then the SDT flag is set to 1. Otherwise, it is set
to 0.
•
Present – the EIT schedule flag in the SDT is set to 1
•
Not Present – the EIT schedule flag in the SDT is set to 0
If an EPG module is available and the schedule is enabled on the output, then both Present
Following and the Schedule flags are set to 1 in the SDT.
For each outgoing service, it is possible to manually set the Major and Minor channel number if
ATSC profile is active for corresponding transport stream.
If “Channel number” is set to “Auto” the numbers will be copied from the input TVCT/CVCT
tables. In “Manual” mode the values are entered in the GUI.

7.3.8 Components
The Components tab allows for the mapping of components through the unit, i.e. video, audio,
etc. This mapping includes manual and automatic modes. The Components Tab is identical for
both MPTS and SPTS.
Page 137 (306)
DMG 3200/3100/3000 – User Manual
Figure 7.24 - Components Tab for IP SPTS
The following mapping modes are available:
Auto All
All PIDs will be mapped to the output
Auto A/V
Only Audio and Video PIDs will be mapped. If multiple Audio
PIDs are available on the inputs, all will be mapped through.
Auto A/V/TTXT
Audio, Video, Teletext and DVB Sub PIDs will be mapped. If
multiple Audio PIDs are available on the inputs, all will be
mapped through.
Manual
It is possible to define your own custom filtering and mapping
rules to get the desired output. Refer to the detailed description
below.
7.3.8.1 Manual Mapping
In Manual mode it is up to the user to define the mapping rules for the components of the
outgoing service. Each outgoing PID requires a dedicated rule; otherwise the default rule
applies.
A component-type PID mapping mode can be set, i.e. the input component type is used to
identify the input PID itself, instead of using the input PID value only. This feature is typically
used to provide a fixed PID line-up at the output, even if the input PID values are changing
dynamically at the input.
To achieve component-type PID mapping, a set of mapping rules are applied to the incoming
PID which matches a specific filter. Several rules/filters can be added, and one PID may match
Page 138 (306)
DMG 3200/3100/3000 – User Manual
more than one rule. However, only one rule (the one with the higher priority) will be applied to
the mapping of the PID.
For example:
Input
Output
Daytime
501 (Video)
600 (Video)
502 (Audio, nor)
601 (Audio, nor)
503 (Audio, swe)
510 (TTX)
Evening
501 (Video)
600 (Video)
502 (Audio, eng)
601 (Audio, eng)
505 (TTX)
505 (TTX)
A set of rules fulfilling this purpose would be:
Component
Type
Language
Incoming
PID
Mode
Outgoing
PID
1
mpeg-audio
nor
*
REMAP
601
2
mpeg-audio

3
mpeg-video
*
*
REMAP
600
4
ttx
*
505
PASSTHROUGH
*
Default
*
*
*
STOP
*
Input
The default rule will in this example stop the input PID 503 as no rule finds a match. Also the
TTX PID will be stopped during daytime as the input PID does not match the PID based rule.
With many rules potentially being active at the same time, it may be hard to foresee the result.
Consequently the GUI reflects the evaluated output PID line-up dynamically as the rules are
defined.
The following manual mapping modes are available:
Stop
Remap
Passthrough
Page 139 (306)
The input component referenced will be stopped
The input component referenced will be remapped to a specified output
PID – this PID will not be reallocated by the system to prevent PID
clashes.
The component will be mapped to the same output PID as its input PID
– this PID may be reallocated by the system to prevent PID clashes.
DMG 3200/3100/3000 – User Manual
In systems with dynamic behavior on the input, it is recommended to create a rule for all PIDs to
be added to the output if a fixed and dedicated line-up is required. This way, it is easier for this
system to decide what action to take when the input changes. In some cases, a lack of
definition will force the system to temporarily stop PIDs.
For example, a TTX PID in Passthrough mode changes on the input to a PID value already
assigned manually on the output. In this case, the PSI system will stop the signaling of that TTX
PID until the system has decided what to do with the TTX PID – i.e. automatically map it to a
new, free PID value.
In an output service, if a video PID with PCR is stopped then this will be stopped
on the output, but the PCR can be extracted and output. This can be used in
cases where you would like to create a radio service using a PCR from a
signaled video PID in the service.
7.3.8.2 Component multiplexing
With Service component multiplexing it is possible to add an Audio, Teletext, DVB
Subtitle, AIT, HbbTV-carousels or private component from another input source to an
outgoing service. This PID will be multiplexed into the outgoing stream and signalled in
the PMT of the service.
Adding components to an outgoing service is done on the Components Mapping section
by clicking the plus button. This will show a selection dialog where all valid Audio,
Teletext, DVB Subtitle, AIT, HbbTV-carousels or private PID that can be selected for
output.
Figure 7.25 - Component multiplexing
Page 140 (306)
DMG 3200/3100/3000 – User Manual
Any input Audio, Teletext/DVB Subtitle source that is not synchronized with the
output video (ie PTS) could possibly have issues with display. Users must ensure
that the added component is synchronized for this feature to be enabled correctly.
If the PID is not synchronized with the output video, no alarms will be raised.

7.4.1.2 Output Redundancy Related Parameters
The Output Redundancy fields are to be used in a system configuration where two IP modules
or services are configured in a redundancy scenario. Refer to Section 10.4 for further details.
Page 146 (306)
DMG 3200/3100/3000 – User Manual
Figure 7.33 - Output Redundancy Panel for IP Modules
The following parameters are available:
Redundancy
Control
Provides the criteria for when to disable the output. Choose from:
•
•
•
•
All – Output TS is disabled if all services are in error
Majority - Output TS is disabled if majority of services (with high priority)
are in error
One - Output TS is disabled if one service is in error
None - Output TS is not automatically controlled
Please note that Source IP needs to be enabled and configured correctly if Output Redundancy
(OSPF) is enabled.
7.4.1.3 Port Settings for IPv6 output
For IP output modules with IPv6, the Port Settings tab is shown below. When using standard
IPv6 address syntax (128 bits, ‘:’ instead of ‘.’), the GUI will interpret the address as an IPv6
address.
7.4.2 Cloned IP Output Module
The Cloned IP Output module has two physical data ports which both contain the same output
represented by one internal port. Service configuration is performed to the internal data port,
and the same service is then output on both physical data ports.
Figure 7.34 – Cloned IP Output Module.
Page 147 (306)
DMG 3200/3100/3000 – User Manual
Configuration of the output streams and ports are similar to that of the standard IP output and
these details are shown in 8.4.1.
7.4.2.1 Unique Configuration on two ports
IP settings can be configured different on the two IP ports in cloned output mode. Parameters
that are able to be changed, can be selected and the new value entered. By default, the
properties of port A are used.
Figure 7.35 –Unique configuration on two output ports
7.4.2.2 Exclusive Output Port Mode
While in Cloned IP output mode, it is possible to enable Exclusive Output in which the following
rules are followed:
Link on both ports
(Default)
Port A is active
Link on B port only
(link down on A
port)
Port A is inactive (link down)
Link on A port only
(link down on B
port)
Same effect as default
Port B is inactive (ie no output bitrate)
Port B is active
When the module is in exclusive output mode only one port is outputting transport streams at
once. If link is down on one port, the other port will take over.
Page 148 (306)
DMG 3200/3100/3000 – User Manual
Where port A is the default port and port B is a backup, used only when port A has link
problems. When link of port A comes back, the system will switch back to use port A (ie
reverting)
In order to enable Exclusive Output Port, the Cloned IP Output module must first be changed to
this mode. This is configured in the Maintenance Center and you can find further details on this
procedure in the Upgrade Guide.
Figure 7.36 – Conversion to Exclusive IP Output Module.
When this feature is enabled this will be displayed in the Redundancy->Output Redundancy
status page.

7.4.3 Dual IP Output
The Dual IP output module allows two individual output interfaces to be connected to network
sources, but for the system, this is exactly the same as two IP output cards. The output streams
can be either SPTS (VBR or CBR mode) or MPTS.
All function and status normally associated with IP output modules are present but the total
Output Bitrate for both IP ports cannot exceed 850 Mbps or 250 services, ie the limit is shared
between the two ports.

DMG 3200/3100/3000 – User Manual
7.4.4 ASI Output Module
For ASI modules, the Port Settings tab is shown below:
Figure 7.39 - Port Settings Tab for ASI Modules
An ASI output module can output up to four separate MPTSs. The ASI output configuration is
similar to that of an IP MPTS output, except for a different Port Settings tab.
The following ASI parameters are available:
Rate [Mbps]
Total ASI output rate - the stream will be stuffed with NULL packets to
maintain the correct fixed bit rate.
Packet Size
TS packet size (188 or 204)
Byte Mode
Byte mode specifies how the TS data is transported over the ASI link:
Burst Mode – In burst mode, all TS-data-bytes are sent without any idle
symbols in between. Maximum data rate in burst mode is 213 Mbps per
port.
Spread Mode – In spread mode, the ASI specification requires at least
one idle byte between each data-byte, and each packet start indicator
(0x47) is preceded with at least two idle bytes. The ASI output stream in
spread mode guarantees that each data-byte is preceded with two idle
symbols. This effectively reduces the maximum data rate to 1/3 of the
maximum ASI output rate, i.e., (213/3) Mbps. If higher rates are
required, use burst mode.
7.4.4.1 MIP Inserter for ASI Output
Please refer to the Terrestrial Solution Configuration Guide for more information
7.4.4.2 ASI Cloned Output
The ASI cloned Output mode allows you to set any available output port as a “monitor” port for
an active one. Service configuration that is performed to the active port is then output on both
physical ports.
In order to configure this, on the active port you can select the Port Settings tab. Here you
have the option to choose an inactive port in which to be used as a monitor port. Once this
Page 151 (306)
DMG 3200/3100/3000 – User Manual
setting is applied, the inactive port will not be able to be configured in the GUI, but will be a
duplication of the active port.

7.4.5 QAM Output Module
Unlike other modules, the QAM module’s Port Settings tab is not modifiable as the parameter
values are set under Outputs  QAM  Device setup.
Although the QAM output has two physical outputs, it carries up to sixteen transport streams.
Internally these streams are modulated by four block QAM modulators each carrying up to four
channels.
The RF connectors on the output are configured as such: the first two block modulators A and
B, output on the port marked as A+B, the last two block modulators C and D output on the port
marked as C+D.
The configuration of the QAM modulator parameters is available in a separate node in the
Navigation Pane, called Device Setup, which is beneath each QAM output node.
The QAM module supports the ITU-T J.183/JCTEA standard where output several transport
streams can be multiplexed into one transport stream using Time Division Multiplexing (TDM).
Currently, this standard is supported for transparent streams only. To enable J.183/JCTEA
support, simply click the corresponding check box.
Figure 7.42 - Device Setup Node
When Device Setup is selected, both modulators can be configured from the resulting dialog.
The figures below show the Device Setup node for Annex A/C and Annex B QAM modulators;
correct values for these parameters can be obtained from respective network operators.

7.4.7.1 Linear Pre-correction on DVB-S/S2 Output.
In order to compensate both linear and nonlinear distortions in the transmission chain, it is
possible to adjust the modulator output to match these characteristics. This is done via the
precorrection configuration page. When using the linear precorrection algorithm, both Gain and
Group Delay correction is supported.
Page 158 (306)
DMG 3200/3100/3000 – User Manual
Figure 7.47- DVB-S2 Output –Linear Precorrection
The graphical view for Gain and Group delay consist of two graphs, the filter characteristics of a
transmission chain (provided by the user) and the system response utilizing the optimized
precorrection filter computed on the MMI card.
Please note that the optimization algorithm for group delay contains some
random elements and might not give the desired result 100% of the time. Since
the optimization runs only if new information is provided, to the user will have to
change one value slightly before pressing Apply to re-optimize and obtain the
desired result.
The graphical view may also be switched to a textual view where the points can be added and
changed. This can be done by pressing the co-ordinates button. In this view, the graph window
ranges may also be changed through “Min X, Max X” and “Min Y, Max Y”. This values can be
chosen freely within reasonable values (Gain: Min X ≥ 0, Max X ≤ 35, Min Y ≥ -5, Max Y ≤5 and
for Group Delay: Min X ≥ 0, Max X ≤ 35, Min Y ≥ 0, Max Y ≤ 300). The restrictions for the points
are as following:
Gain:
•

The available configuration parameters in the GUI will not be documented in detail. The
parameters are according to the DVB-T2 specification, ETSI EN 302 755 v. 1.2.1 (2010-10).
The configuration of a DVB-T2 transmitter requires a good working knowledge of this
specification as well as the DVB-T2 implementation guidelines, ETSI TS 102 831. Chapters 4
through 6 of the implementation guidelines is a good place to start with regard to a high level
understanding of the parameters involved.
The user interface attempts to verify that the chosen combination of parameters is valid. Invalid
entries will be highlighted in red and “Apply” will not work unless errors have been corrected.
The “FEC blocks” and “Bitrate” are status parameters that indicate the expected payload
carrying capacity of the chosen parameters.

7.5 Output Options
7.5.1 Enable/Disable Services in Outgoing MPTS.
It is possible to enable and disable a service in an MPTS output in addition to enable/disable the
complete MPTS.
In order to do this, use the tick box on the output of each service in a MPTS once expanded.
Figure 7.49 – Enable/ Disable services in MPTS.
7.5.2 Virtual MPTS Output
This feature provides the capability to generate the NIT including Delivery System Descriptor for
MPTS outputs currently not configured by the unit. The Delivery System Descriptor is defined
as part of the MPTS setup; data inserted will be included in the NIT.
For the ASI, COFDM, or QAM output, the virtual output provides this feature. It may be added
from the Outputs page using the Add Virtual button enabling the signaling of other transports
not present in the same unit.
Clicking the Add Virtual button displays a dialog similar to the one shown below, allowing you
to insert the Network ID, TS ID in the Transport tab, followed by the QAM configuration (for
this example) in the Port Settings tab.

7.5.3 MPTS Transparent Mode
With MPTS Transparent Mode, an input stream is forwarded to the output without any
processing, i.e. output equals input, including null packets (for modulated outputs, null packets
will be removed and re-added to exactly fit the configured modulation bit rate).
When setting up a transparent stream, the Add MPTS button is not used. As with an SPTS,
simply drag an MPTS from the list of available MPTS’s over to the output pane. In the output
pane, the name of a stream will indicate whether it is transparent or not (as shown in the figure
below).

7.5.4 MPTS Semi-Transparent Mode
The semi-transparent mode is a subset of the transparent mode. The semi-transparent mode
allows the user to replace some selected components. Currently this feature allows for
replacement of the NIT table only.To configure semi-transparent mode, create a transparent
output, and then double click on it to access the Stream Properties dialog. Then, go on to the
Transparency tab to configure the new NIT Source (Generate NIT A ). In this mode, for IP and
ASI output modules, null packets are always removed and re-added.

stopped. It is possible to click magnifying icon and select from list of services found on the input.
When a service is added to the filter list, the following will occur:
•
•
•
•
All PIDs that are part of a filtered service will be stopped.
PIDs shared with non-filtered services are not stopped.
PIDs explicitly mapped through/remapped by user (in the PID Import/Remap section),
that belongs to a filtered service, will not be stopped.
If PAT re-generation is enabled, PMT PIDs of the filtered services is stopped.

7.5.6 Service Priority Selection
For each service on the output it is possible to set the service priority and this determines from
which services packets are dropped if the total rate exceeds the constant bit rate of the output
MPTS.
This is configured from the Service tab under Service Properties for each program under an
output MPTS.
Service priority is supported on all output cards. The default value for all services is high priority.
Figure 7.55– Service Priority Selection in service Properties.
If low or medium priority packets are discarded due to exceeding the band with limitations, the
major alarm “Low/medium priority packets dropped” is set.
If the link is so overloaded that discarding all low/medium priority packets is not enough, the
behaviour is to empty the output buffer.. If this happens, the critical alarm “Output buffer
overflow” is set. This alarm will mask the “Low/medium priority packets dropped” alarm.
Figure 7.56– Alarm with Low/ Medium Packets dropped.
Any packets dropped due to service priority will be counted, and the total number is displayed
per MPTS on the Output View.

7.6.6 PSI Synchronization
Page 175 (306)
DMG 3200/3100/3000 – User Manual
PSI Synchronization allows the operator to synchronize NIT and/or SDT tables between units
that are part of the same DVB network(s) – enabling generation of a complete NIT and/or SDT
table. If two or more units perform PSI synchronization with each other, they will both signal all
transport streams in shared DVB networks.
Important points to note when using this functionality:
The management interface on the MMI card is used to establish TCP/IP connections between
units to be synchronized; hence the required network connectivity is a prerequisite.
All synchronization is initiated manually by the operator. Changes do not take effect until either
Retrieve Now or Remove (explained below) is clicked. This also means that if PSI is updated on
an external unit (e.g. a new transport stream is added/removed, remap SDT parameters, etc.)
the operator must manually perform another synchronization to retrieve these updates.
The version number of NIT may be different between units, but the table content is the same.
This may cause a small delay for a STB when zapping between transport streams provided by
different units as it would appear to the STB that a NIT update has occurred.
The PSI Synchronization functionality is accessible from the PSI dialog by clicking on the
respective tab:
Figure 7.66- PSI Synchronization Tab
To add a unit for PSI synchronization, enter in the MMI IP address of the external unit (in dotted
quad format) and click Add.
Now a table entry will be visible in the Retrieve PSI tables from external units section of the
dialog, identifiable by the IP address.
The following parameters are displayed:
IP Address
IP address of the external unit MMI management interface
Filter by Domain
(Optional)
Optionally select the PSI to synchronize from a specific domain
from the remote unit
Filter by Net
(Optional)
DVB network ID – if specified, only download external sections
from this network. Otherwise, all sections are downloaded
Page 176 (306)
DMG 3200/3100/3000 – User Manual
regardless of the network.
SDT
Check this box to synchronize SDT
NIT
Check this box to synchronize NIT
Status
Provides feedback on result of last synchronization attempt; if no
attempt has been made, Not Synced is displayed.
Date
Action
Time and date of last synchronization attempt; if no attempt has
been made, this field is empty.
Retrieve Now initiates a download of selected sections from the
external unit. If the operation succeeds, the Status displays OK
and the output PSI will automatically be regenerated using the
received external sections.
Remove removes the table entry and the output PSI is
automatically regenerated so that all traces of external transport
streams from the external unit are removed.
7.6.7 Inserting Generic Descriptors
The Generic Descriptor insertion functionality (accessible from the PSI dialog by clicking on the
respective tab) allows insertion of arbitrary PSI descriptors into selected DVB output table
descriptor loops. This feature is useful when an important descriptor is private or currently
unsupported.
Figure 7.67 - Generic Descriptor Tab
Each entry displayed in the table corresponds to a single generic descriptor placement.
Clicking on
allows new descriptor entries to be inserted, initiating a sequence of context
dependent configuration options via drop down boxes described in the following tables:
Table
Selected desired output table
Playout Placement
A series of table dependent drop down boxes to select the desired
descriptor loop locations:

DMG 3200/3100/3000 – User Manual
desired output TS
Service ID – DVB service ID of desired output service
Component – input PID of an elementary_stream (not
remapped value)
All drop down boxes provide a list of currently available
options together with the option to manually define an explicit
value. After manually defining a value, click Next to continue
the configuration process.
Individual table placement instructions are provided in the
Generic Descriptor Loop Placement Instructions below.
Hex Data

contain the correct 2 byte tag and 2 byte length. Descriptors with
invalid descriptor_length will be rejected.
Action
Depending on the current configuration step, one of the following
buttons will be displayed:
Next – displayed when defining a new descriptor; click to validate the
descriptor.
Retry – displayed when a new descriptor fails descriptor_length
validation; correct the error and click to retry validation.
Add – displayed when a new descriptor passes descriptor_length
validation; click to add the descriptor to output PSI.

7.6.9 PSI Generation Setup
The Setup tab allows for modification of PSI generation settings like table versioning scheme,
CA descriptor placement, PMT caching, and so on.
Page 180 (306)
DMG 3200/3100/3000 – User Manual
Figure 7.69- Setup Tab
Table versioning
scheme
Normally the version numbers of the PSI/SI tables are incremented by
one for each change. This parameter provides the means to force
outgoing tables to use Odd or Even numbers.
This configuration is used in conjunction with Output Redundancy to
differentiate two sources (Main and Backup) from each other, ensuring
that receivers will detect if a redundancy switch has occurred. Should a
switch occur, the receivers will reprocess the PMT and detect a
potentially new PID line-up.
The drop down box provides three options:
Normal – version numbers are incremented normally
Force Odd – version numbers are incremented using odd numbers
only
Force Even – version numbers are incremented using even numbers
only
CA descriptor
placement
Some STBs have specific requirements on the location of the CA
descriptor in the PMT. By default, the unit will place the CA descriptor
in both Service and Component level in the PMT.
The drop down box provides three options:
Service Level – CA descriptor is in the service loop only
Component Level – CA descriptor is in the component loop only
Service and Component Level – CA descriptor is in both loops
PMT caching
Checking this option ensures that the output will not lose the PMT even
if the stream’s input disappears.
NIT manual version
Forces the NIT version number to the given value
Include EIT
signaling in NIT
Enables the EIT linkage descriptor (0x04) to be excluded or included in
the NIT generation.
If EIT schedule information is present, by default, the system adds a
linkage descriptor in the NIT. If EIT is present in multiple transports,
then according to the DVB standard, the NIT will contain multiple
linkage descriptors.
When all transport streams contain the EIT schedule, some STBs jump
to a different transport when using the EPG, causing the current
program not to be displayed concurrently with the EPG. To prevent this
behavior, we recommend that the linkage descriptor be excluded from
the NIT.
7.6.10 DVB  ATSC, ATSC  DVB Conversion
When the output PSI mode is set to ATSC, some selected information will be translated from
the DVB format to the ATSC format. Also the DVB has a larger reserved PID range than ATSC.
Page 181 (306)
DMG 3200/3100/3000 – User Manual
The following information is translated:
Service name
(DVB) SDT  (VCT) Short channel name
(VCT) Short channel name  (DVB) SDT
Audio AC3 descriptor
The AC3 audio component is signaled with different stream type in DVB and ATSC.
DVB stream type in PMT: 0x06
ATSC stream type in PMT: 0x81
In DVB the AC3 component has an additional AC3 descriptor in the PMT.
DVB  ATSC: Changes stream type and removes AC3 descriptor.
ATSC  DVB: Changes stream type and adds the Additional AC3 descriptor.
PID Ranges
DVB reserved PID range: 0  31
MPEG/ATSC reserved PID range: 0  16
The conversion from ATSC  DVB may therefore involve remapping of component PIDs if the
incoming PIDs are in the reserved output range.
7.6.11 SI Domain Support
The SI Domain allows for multiple outputs to be defined with the same DVB triplet (NET ID, TS
ID, SID) as some system designs require one unit to transmit on two different output domains,
e.g. IP and cable.
In the domain concept, each domain is independent of each other with respect to SI validation
and generation. In other words, within a unit the same output triplet, ie
Network/Transport/Service ID, can be used as long as they belong to a separate domain.
Page 182 (306)
DMG 3200/3100/3000 – User Manual
Figure 7.70- PSI Domains
This feature is not visible unless an additional output domain has been created. To create a
domain, select Outputs  PSI  Domains. Then, enter an appropriate name for your domain
in the Name field and click Add.
Once a new domain is created, the domain parameter will appear on the Transport tab (8.3.1).
It is possible to add multiple output domains.
8 Encoder and Transcoder Configuration
8.1 General information
In the Sencore platform, there are three types of Coder modules available. The encoder
module takes uncompressed digital signals from SDI input ports while the transcoder and
multiscreen transcoder modules take compressed digital signals from the input cards. The
output from all module types are compressed digital signals than can be routed to any of the
output cards in the unit.
Encoding capabilities (HD/SD and the number of channels) of the encoder and transcoder
modules can be changed via options and licenses. These modules are configured separately
but have the same video encoding parameters. The common parameters for the encoder and
transcoder are described in section 8.4 while section 8.6 covers the multiscreen transcoder
module and its specific configuration parameters.
The Coders view in the Navigation Pane gives a summary of the encoders and transcoders
present.
Page 183 (306)
DMG 3200/3100/3000 – User Manual
Figure 8.1: Coders View
The Coders View contains the following information:
Slot

Type
Type of coder module.
Service
Encoder: Number of services generated by the encoder module.
Transcoder: The number of transcoded services.
Input Bitrate
[Mbps]
The input bit-rate to Transcoder modules. Nothing is reported for
encoders.
Output
Bitrate[Mbps]
Total bit-rate including PSI/SI, transmitted to the backplane. The bitrate may increase when a service is copied to multiple outputs.
8.2 Encoder Configuration
The encoder modules have input ports that take a digital input signal, in the HD-SDI and SDI
format, and convert this signal into a compressed transport stream. One SDI input can receive
one video channel and multiple audio channels.
The encoder modules can, in addition to the main video, produce a low resolution version of the
video – PiP (picture in picture). The PiP video is multiplexed with the same audio as the main
service. The resulting PIP service is then also available to select as an output service. PCR is
embedded on the PIP video PID.
The HD-SDI encoder module with 2 channels supports both HD-SDI and SD inputs. The SDI
encoder module with 4 channels supports only SD inputs.
Page 184 (306)
DMG 3200/3100/3000 – User Manual

are organized into different sections selectable from the tab menu on top. Common sections
Page 185 (306)
DMG 3200/3100/3000 – User Manual
for encoder module and transcoder module are described in section 8.3.34. The following
sections describe only information specific to the encoder.
8.2.1 Source Parameters
This page is used to configure the input source parameters for the encoder port.

The following parameters are available for source configuration:
Frame rate
Specify incoming frame rate from drop down list.
50Hz
59.94Hz

1080i
720p
Available SD formats are:
576i
480i
A HD Encoder supports both SD and HD formats. A SD encoder supports
SD formats only.
Signal Loss
Available options are:
Colour Bar: Encoder Produces Colour Bar when input signal is lost.
Black Picture: Encoder Produces Black Picture when input signal is lost.
Preset
Page 186 (306)
Configuration Presets can be used to help configuring the
encoder/transcoder optimally for a specific scenario with respect to
content and/or bitrate:
DMG 3200/3100/3000 – User Manual
These Presets are applied as a template in the sense that even after a
preset has been chosen; the user can access and alter all the
parameters as normal.
The SDI input format must be explicitly configured, it is not auto detected. The encoder does
not support any video format conversion. The input format must match the encoding format.
Figure 8.4 -Encoder Frame Rates
8.2.2 Pre Processing Parameters
Pre-processing is a collective term covering all processing of the video signal done prior to the
encoding process. The purpose of pre-processing is twofold.
•
•
Make the video signal easier to encode.
Analyze the video and give advance information to the encoding process
Figure 8.5 – Encoder Pre Processing parameters
Page 187 (306)
DMG 3200/3100/3000 – User Manual
Horizontal Rescale
The horizontal resolution (pixels per line) is defined by the selected
video format, but can be reduced. The available options depend on
the selected video format on the Source Tab. Reducing horizontal
resolution will make it possible to use lower bitrates when encoding
since resolution is reduced before encoding.
Pre-Deblocking
Strength
The Pre-Deblocking filter attempts to smoothen macro block edges
introduced by (MPEG) encoders earlier in the chain. The deblocking
filter applies a “smoothing” effect to the incoming video. Its purpose
is to blend in sharp, high-frequency (sharp edged) blocking artefacts
to make them less visible. Too much filtering will make the images
“soft”.
MCTF Strength
MCTF (Motion Compensated Temporal Filter) is a filter that can be
used to remove noise in the incoming video signal. It recommended
to only use MCTF on source signals with a significant noise
problem, or when extremely low encoder bitrates are configured
Skin Tone
Detection
When enabled, the encoder detects portions of the video containing
skin tones and may increases the subjective video quality.
8.2.3 Audio Parameters
On the encoder module, there are one (for SD mode) or two (for HD mode) general purpose
audio encoders per channel. These channels support MPEG-1, AAC-LC, HE-AACv1 and HEAACv2 encoding and AC-3 (Dolby Digital) pass through. In addition there are up to 12 MPEG-1
encoders or 4 AAC-LC encoders that can be distributed among the channels on a board. A
mixture of MPEG-1 and AAC encoders are allowed per board and this is outlined in the table
below.

8.3 Transcoder Configuration
In the DMG platform, the transcoder module is used to receive services from any of the input
cards and change the codec, bit-rate or resolution of the service which can then be routed to any
of the output modules. When configured, the input video is decoded, rescaled and then reencoded.
The transcoder can operate as a 2 channel HD transcoder module or a 4 channel SD
transcoder module depending on options and licenses. The HD and SD transcoders can both
decode HD and SD video. The HD transcoder can encode HD and SD, while the SD
Transcoder can encode SD only. All incoming PIDs that are not transcoded will be kept in sync
with video after transcoding.
The transcoder status and configuration page is accessed by clicking on an encoder module in
Navigation Pane.
The page contains the following information:

Click edit and the transcoder configuration pages will be displayed. The configuration
parameters are organized into different sections selectable from the tab menu on top.
Common sections for encoder module and transcoder module are described in section 8.3.34.
The following sections describe only information specific to the transcoder.
8.3.1 Source Parameters
For viewing transcoder source parameters, please select the Source tab.
Figure 8.16 – Transcoder Source View
The following parameters are available:
Service Name
The name of the incoming service that are transcoded. This field is
empty if no service is selected.
Service Type
Service type received for this service. This is meta data in DVB SI and
may not correspond to the actual video codec and format received.
The service type corresponds to the Service type settings in the

PID -> PID number received
•
Type -> Type of component for selected PID
•
Rate -> Bit-rate for selected PID
•
Info -> additional information such as language code
•
Output -> PID reference of the output component and
processing
If AFD is present in the incoming video, the transcoder will encode the AFD in the picture
according to ETSI TS 101 154 V1.9.1 and A/53 Part 4 2009. The transcoder does not support
to change the incoming AFD or to add a default AFD value when AFD is not present in
incoming video.
8.3.2 Pre-Processing Parameters
Pre-processing is a collective term covering all processing of the video signal done prior to the
encoding process. The purpose of pre-processing is twofold.
•
•
Make the video signal easier to encode.
Analyze the video and give advance information to the encoding process

HD Module: 1080i, 720p, 576i, 480i and
Transparent.
•
SD Module: 576i, 480i and Transparent.
Horizontal Rescale
The horizontal resolution (pixels per line) is defined by the
selected video format, but can be reduced. The options
depend on the selected video format on the Source Tab.
Reducing horizontal resolution will make it possible to use
lower bitrates when encoding since information is removed
before encoding.
Pre-Deblocking
Strength
The Pre-Deblocking filter attempts to smoothen macro block
edges introduced by (MPEG) encoders earlier in the chain.
The deblocking filter applies a “smoothing” effect to the
incoming video. Its purpose is to blend in sharp, highfrequency (sharp edged) blocking artifacts to make them less
visible. Too much filtering will make the images “soft”.
Skin Tone Detection
When enabled, the encoder detects portions of the video
containing skin tones and may increases the subjective video
quality.
Rescale: Down scaling is supported. De-interlacing is not supported, so an
interlaced format must be transcoded to another interlaced format. A
progressive format may be transcoded into either interlaced or progressive.
Page 201 (306)
DMG 3200/3100/3000 – User Manual
Figure 8.18- Transcoder configuration of Frame Rates.
The picture above shows how the configured Frame Rate defines the allowed Rescale options.
The horizontal rescale option list is defined after the Frame Rate and Rescale are selected. The
Frame Rates can be selected between 50/59.94/60. The Rescale can be selected after the
Frame Rate is selcted.
In Transparent mode, an warning alarm will be given if the input format cannot be matched.
This can for example be the situation on a SD transcoder if the input signal is HD. The
transcoder will keept the last format in this case.
The following options are available for PCR :
As source
The PCR is passed through on the incoming PID value.
Video PID
The PCR is embedded on the video PID regardless of origin.
Separate PID
The PCR is sent on a separate PID regardless of origin.
Default PCR PID is 8180. It will only get this default value if that PID value
is not already in use in the transport stream.

Page 208 (306)
DMG 3200/3100/3000 – User Manual
Figure 8.24 – Video Extended configuration
The following parameters are available for video extended configuration:
Weighted
Prediction
In H264 mode, the encoder can employ Weighted Prediction to improve
the coding efficiency of fades and dissolves. It is recommended to have
this enabled.
Fade Detection
When a fade is detected, the GOP structure is adjusted to improve the
encoding efficiency of the fade. It is recommended to have this enabled.
Scene
When a scene change is detected, the GOP sequence is adapted so that
the new scene starts with an I frame. It is recommended to have this
enabled.
Change
Detection.
GOP Size
Sets the number of frames in a GOP.
GOP Struct
Sets how many B frames there should be between P frames
GOP Mode
Selects open or closed GOP. It is recommended to have this to “open”.
Only use closed if STB’s do not support open GOP.
Dynamic
Dynamic GOP mode lets the encoder adjust the GOP structure
depending on content. Most GOPs will be of the length set in “GOP
Size”, but when the content requires a different structure, the encoder will
adjust the GOP to achieve better video quality. It is recommended to
have this enabled.
Max/Min
Applicable in Dynamic GOP mode. Sets the min and max number of
successive B frames allowed in the GOP structure.

DMG 3200/3100/3000 – User Manual
8.4.3 MPEG-2 Parameters
The following parameters are available for MPEG-2 configuration:
Figure 8.25 – MPEG-2 configuration
Intra DC Precision
Quantization resolution of the DC (luminance) component in intra
frames. Normal setting is 8 bits. Consider to increase precision when
encoding at high bitrates
Video Buffer
Verifier Max Delay
This sets the size of the VBV buffer. The value should be left at
the default (728ms). Reducing the VBV buffer is a technique often
used to lower the video delay, but it can seriously compromise
video quality by forcing excessive quantisation to accommodate Iframes. This can cause poor references, poor video and I-frame
pulsing artefacts.
Alternate Scan
Defines how transform coefficients are handled. Two modes are
available ; MPEG-1 or alternate. Alternate provides superior results
with interlaced video and should be the default setting.
8.4.4 H.264 Parameters
The following parameters are available for H.264 configuration:
Page 210 (306)
DMG 3200/3100/3000 – User Manual
Figure 8.26– H.264 configuration for Encoders
Reference B-Frames
Enables B frames to be referenced to I, P or B frames. When
disabled, B and P frames can only reference I or P frames.
8x8 transform
Available in high profile mode only. This enables 8x8 transform
for residual coding. This can provide significant advantages for
HD encoding.
CABAC
CABAC (Context Adaptive Binary Arithmetic Coding) is an
entropy coding scheme introduced in H264. When enabled,
CABAC is used instead of CAVLC. CABAC is the most efficient
of the two, and should be the default choice. Some legacy
decoders might not support CABAC.
Loop Filter Mode
This controls the encoder output de-blocking loop filter. The
loop filter is designed to remove blocking artefacts resulting
from the compression process. Settings should reflect customer
preferences and content. The trade-off is between visible
artefacts and a softening of the video, especially sports and
other difficult, high-motion content. Detail, especially grass, can
look better with this feature disabled.
Loop Filter
When the loop filter is enabled, the Alpha offset allows the user
to adjust the strength of the loop filter i.e. how much the video is
softened. Negative values will soften the video less, but at the
risk of showing more blocking artefacts. Positive values will
soften video more, but at the risk of removing more detail. The
value ‘0’ is often considered to be a good compromise.
Alpha CO offset.
Loop Filter
Beta Offset.
Page 211 (306)
When loop filter is enabled, the Beta offset allows the user to
adjust the threshold for what the filter considers a blocking
artefact. A negative value will lower the threshold and preserve
more detail but at the risk of showing more blocking artefacts. A
positive value will remove more blocking artefacts but may also
DMG 3200/3100/3000 – User Manual
remove more detail. A value of ‘0’ is often considered to be a
good compromise.
Video Buffer Verifier
Max Delay
This sets the size of the VBV buffer. The value should be left at
the default (1000ms). Reducing the VBV buffer is a technique
often used to lower the video delay, but it can seriously
compromise video quality by forcing excessive quantisation to
accommodate I-frames. This can cause poor references, poor
video and I frame pulsing artefacts.
IDR Frequency
Sets how often I frames shall be converted to IDR
(Instantaneous Decoder Refresh) frames. IDR points are intra
frames without past references. The IDR frequency can be
important for decoders offering fast trick play (fast forward /
rewind).
8.5 Universal Broadcast Transcoder Configuration
The Universal Broadcast Transcoder can transcode up to 16 SD service without PIP, 12 SD
services with PIP or 4 HD/SD services with PIP. The transcoder can take any conventional DVB
service (HD/SD, MPEG-2 or H264) as input. The module consists of four separate transcoder
blocks A, B, C and D.
On the Coders->Setup Hardware page, the Universal Broadcast Transcoder can be configured
either HD or SD mode per block. Once configured, the transcoded services will appear as
SPTS/MPTS inputs to the unit. These services can be output through an output interface just
like any other service.

8.6 Universal Multiscreen Transcoder Configuration
The Universal Transcoder- Multiscreen can take up to four traditional broadcast services (HD
or SD) as inputs and convert/transcode these into several new services with profiles suitable
for reception by multiple different devices. These profiles normally differ in bitrate, resolution,
profile, level etc.
The Universal Transcoder- Multiscreen can take any conventional DVB service (HD/SD,
MPEG-2 or H264) as input. The module consists of four separate transcoder paths A, B, C
and D. All the profiles generated by the same path will be key frame aligned. If a single path
does not have enough processing power to generate the required profiles, the processing
power of several paths on the same module can be combined. Profiles generated by
combined paths will be key frame aligned.
When the Universal Transcoder- Multiscreen is configured and enabled, the profiles generated
will appear as MPTS inputs to the unit. These services can be output through an output
interface just like any other service.

EBU subtitling on same language, the transcoder will select subtitling source based on
the type priority configured.
To ensure interoperability with segmenters and multiscreen clients, the values of GOP Size and
IDR Frequency have to be selected with these devices in mind. The IDR-to-IDR Time
represents the smallest segment size that can be produced.
8.6.2 Audio Parameters
On the Universal Transcoder- Multiscreen there are two audio transcoders per path. These
support MPEG-1, AAC-LC, HE-AACv1 and HE-AACv2 as input and output codec. AC-3 and EAC-3 input is also supported (decoding only - not encoding) if the Dolby® Digital Plus
Professional Decoder license is installed on the module. Multichannel inputs (e.g. 5.1) will be
downmixed to 2.0 as part of the transcode process.

The question mark icon opens up a detailed explanation of the various modes configurable
through the Use Case setting. Each path consists of a finite amount of video processing power.
Fundamentally the encoding complexity of a HD profile is much higher than the complexity of a
low resolution profile. Therefore the Universal Transcoder- Multiscreen can encode more low
resolution profiles than high resolution profiles.
The resource can be configured in 16 different Use Cases or modes. The various modes give
the possibility of partitioning the processing power to match the multiscreen profile requirements
of any device. The Use Cases available are:

8.7 Statistical Multiplexing
The principle of statistical multiplexing is that a group of video encoders/transcoders (referred to
as a StatMux group) shares a fixed quantity of TS bandwidth. The bandwidth is distributed by a
centralized StatMux controller, and the program with the most complex video may be allowed to
use more bandwidth than programs with less complex video or with a lower priority.
The statistical probability that all programs in a multiplex shall demand a high bit rate at the
exact same time decreases when the size of the multiplex group increases.
The motivation for a StatMux system is to either:
•
Avoid spending bandwidth on simple video sequences in order to free up capacity for
new programs in the multiplex.
•
Distribute available multiplex bandwidth between programs in order to increase overall
video quality (VQ), by minimizing overall quantization (QP)
8.7.1 Modules Supported
The StatMux controller is located on the MMI module of the unit. This is responsible for the
control of the StatMux groups and modules.
The following encoder/transcoder modules types are supported:
•
•
•

9 Digital Processing Modules
9.1 Audio Leveling Module
The Audio Leveling card is able to adjust the audio level for up to 250 audio PIDs. The leveling
process operates purely in the digital domain which means there is no signal degradation
associated with this process.
The concept with the Audio Leveling card is to be able to adjust all the outputs to the same
audio level so that zapping between channels will be more comfortable.

The EPG node has three sub-nodes:
•
Status – the Status node displays the EPG status for all outgoing transport streams
aggregated according to each network.
•

The following parameters are available for configuration:
Automatic EIT Source Selection
Matching Criteria
Used to determine which component(s) of the triplet (NET ID, TS ID,
and SID) will be used to match EPG information with its service.
Multiple Match Action
Lists the course of action that should be chosen if there is more than
one service available for the matching criteria.
The fewer parameters you match on, the higher the chance is to get multiple
matches
Double Input Buffer
Double input buffering allows for a more intelligent EPG update algorithm. In addition, it also
enables the system to flag warnings if the input is corrupt.
Page 246 (306)
DMG 3200/3100/3000 – User Manual
The following parameters are available:
Input Data Completion
Timeout
If the EPG for a particular service is not complete within this
timeout, then the system will play the already received data.
The default value is 60 seconds.
Inter Table Update
Timeout
The EPG data is transmitted in different tables, according to the
time which the data describes. For example: EPG for day one is
transmitted in a different table_id compared to EPG for day six.
This parameter specifies the duration the system should wait
between table_ids before it starts to regenerate the content.
If the parameter’s value is low, it is likely that the system will
regenerate several times during the transfer of EPG covering
many days.
The default value is 300 seconds.
EPG Sync Peer Units
In a system with many units, e.g. in a QAM network, there may be a few units belonging to
the same network. In this system, the outgoing EPG should signal all the services.
To synchronize your units, go to EPG  Setup and list the IP address for each remote
EPG module (not IP address for the MMI) under EPG Sync Peer Units.
Figure 9.6 - EPG Sync Peer Units
The EPG module’s IP address can be configured under the Admin node.
Currently the system only supports synchronization of up to five remote EPG
modules.

DMG 3200/3100/3000 – User Manual
Manual EIT Source PID
By default, all PID 18 information is automatically sent to the EPG processing card. If EPG
information for certain inputs is not on PID 18, it is possible to manually set the PID value using
the Manual EIT Source PID box.
Figure 9.7 - Manually adding an EIT Source PID
Design of the EPG behavior is based on the ETSI EN 300 458 V1.9.1 (2009-03)
standard along with ETSI TR 101 211 V1.9.1 (2009-06) guideline.

Double click on the output transport stream of your choice
Select the EPG tab
Check the Add EPG checkbox
Finally, set the parameters accordingly
The output transport stream will contain schedule information for all channels within the
same network, grouped according to outgoing Network ID.
EPG can be enabled on more than one transport stream within a network – all these
streams will then carry full schedule information, if they are available from the source.
The EIT schedule will be merged with the EIT Present/Following and Actual/Other.

9.3.1
Playout Rate, Playout Limit, and Priority
There are three parameters that can be modified when configuring your schedule
information:
Playout Rate
The amount of bandwidth you want to allocate for schedule and
present/following information (the higher the playout rate, the shorter the
rotation time).
Playout Limit
The amount of schedule information being sent out.
Priority
The number of times schedule information for the next 12 hours is
repeated in your carousel.
Assuming 1 rotation = r, the figures below illustrate these three parameters and how they
can influence the output of schedule information.
1 Rotation
First 12 hours of EPG data
Slow Playout Rate = X
Data being transmitted in 1
rotation
1 Rotation
Fast Playout Rate = 2 X
Figure 9.9 - Setting a Playout Rate
Figure 9.9 above illustrates the amount of schedule information sent in one rotation if the
Playout Rate is modified.
•
•
In the first box, suppose the Playout Rate is X.
In the second box, we double the Playout Rate, effectively increasing it to 2 X.
Consequently the size of one rotation will be halved, making it equivalent to ½ r.
When choosing a suitable Playout Rate, be aware that this also includes
present/following – Actual and Other.
If the Playout Rate is too low, present/following actual will be given priority
over present/following other; schedule will be inserted if/where there is room.

Playout Limit is modified.
•
•
In the first box, suppose the Playout Limit is L.
In the second box, we reduce the Playout Limit to ½ L. This reduces the amount of
schedule information being output. Consequently the size of one rotation will be
halved as well, making it equivalent to ½ r.
1 Rotation
4x
Figure 9.11 - Setting a Priority
To improve the time it takes for schedule information to load, you can assign a Priority
value for the next 12 hours of data. Suppose you choose 4x, then the 12 hours of data
will be repeated four times in one rotation. Consequently, this will increase the size of
your rotation.

9.3.2 EIT Source Setup
Once the output transport stream is setup, the information will be displayed in the EPG node.
Figure 9.12 - EPG Node
If multiple services are available for the matching criteria, a drop down box is displayed under
EIT Source; pick the best course of action:
Auto
Corresponds to the value chosen in the Setup node, under Multiple Match
Action .
Stop
Ensures that no schedule information is transmitted from this service. If no
drop down box is displayed, it means that there is only one source available
based on the matching criteria.
XML
Specify an XMLTV tag name for schedule information. This relies on EPG
XMLTV import which is covered in the Sencore EPG XMLTV Interface
document.
By default, if no tag is specified, this will be <NetID>.<TSID>.<ServiceID>
corresponding to the output service,
Manual
Manually specify an incoming source (Slot, Port, NetworkID, TSID,
ServiceID) of EIT information
10 Redundancy Support
The unit supports several types of redundancy. While each redundancy module is aimed to solve
different problems, the system handles all of the modules in a similar way, providing some general
parameters to control the switch delay and which triggers should be active for each module.
10.1 Input Redundancy
The goal of input redundancy is to prevent failures outside the system from resulting in errors on
input cards.
Page 252 (306)
DMG 3200/3100/3000 – User Manual
Input redundancy is managed by the Man Machine Interface (MMI) board which determines when
to switch:
•
From one service (Main) to another service (Backup), or
•
From one port (Main) to another port (Backup).
However, it is possible that both these services and ports have different content.

Page 253 (306)
DMG 3200/3100/3000 – User Manual
Backup – inputs are routed from the backup input source
Click Switch to change the current active input. If the current active input is Main, the input
source will switch to Backup and vice versa. For port-based input redundancy entries, an
additional Remove button is visible. Click Remove to remove the port for which input
redundancy is configured.
10.1.1 Configuring Service-based Input Redundancy
Service-based redundancy is set up under the Outputs node. Double click on a service of your
choice to access the Service Properties dialog. Under the Input Redundancy section, select
the appropriate parameters.
Figure 10.2 - Configuring Service-based Input Redundancy
The following parameters are available:
Backup source
Switching mode
Assign a backup service; choose None to disable input redundancy.
Select a suitable mode for each redundancy pair. The following
modes are available:
Off – Stop switching whether it is on main or backup
Once – Switch from main to backup when an alarm occurs on main
and remain there
Floating – Switch when an alarm is set on the service that is active,
ignore clear alarms
Reverting – Switch to backup only if there is an alarm on main but
not on backup; switch back when alarms on main are removed or set
on backup (this is the recommended mode).
Input redundancy on Scrambled MPTS inputs must be configured carefully. This is
because if the input must be descrambled it is not possible to select different
descrambler modules for each service (main and backup). In other words, all inputs
to the descrambler must be routed from the same input source. Currently the system
does not enforce this requirement; hence it is recommended that caution be
exercised when combining descrambling with input redundancy.
10.1.2 Configuring Port-based Input Redundancy
Page 254 (306)
DMG 3200/3100/3000 – User Manual
Port-based redundancy is set up under the Redundancy  Input node. Click on the Add Port
button (see Figure 12.3) and the Add Port Redundancy dialog below will appear.
Figure 10.3 - Configuring Port-based Input Redundancy
Main Port
Assign a main port
Backup Port
Assign a backup port
Mode
Select a suitable mode for each redundancy pair. The following modes are
available:
Once – Switch from main to backup when an alarm occurs on main
and remain there
Floating – Switch when an alarm is set on the service that is active,
ignore clear alarms
Reverting – Switch to backup only if there is an alarm on main but
not on backup; switch back when alarms on main are removed or set
on backup (this is the recommended mode).
When using port-based input redundancy, it is intended to have the same input
structure for both main and backup ports.
Port-based input redundancy applies to transparent transport streams and
imported PIDs.
10.1.3 Alarms that cause Switching
The system will automatically switch from main source to backup source based on the
presence of alarms that are selected in the Redundancy Switching Triggers page below.
Switching Delay
Page 255 (306)
Parameter is added to mention the number of seconds for the module
to switch connections from one backplane to another when alarm
occurs.

The switching hysteresis is not configurable
MMI functionality remains on the same card after a switch
Switching can be done manually via the GUI
Switching behavior depends on the switching mode set individually for each
pair
Alarms that are filtered through the alarm filter GUI will not trigger source
switching
10.1.4 Input Redundancy and the MMI
Input redundancy does not affect MMI functionality. If the main input module is configured as
supporting the Man Machine Interface (MMI), this configuration will remain even though all input
sources are switched from Main to Backup card.
Page 256 (306)
DMG 3200/3100/3000 – User Manual
10.1.5 Seamless Input Redundancy
The Seamless IP input module allows two input interfaces to be connected to different network
sources, but for the system, this is a single module. Configured multicasts are subscribed to on
both interfaces. Depending on the configuration, there are options for these multicasts must
come from the same or different source.
10.1.5.1
Seamless IP Interface selection
For all Seamless IP input modules, it is possible to set the preferred port and/or redundancy
switching mechanism. This is available on the Admin page of the Seamless IP Input module:
Figure – 10.5 Seamless IP interface selection
The values here represent the following modes:
Floating
Port A is the default port and on a failure, Port B will be used. The
redundancy will not switch to Port A again until Port B fails.
Port A
Port A is the default port and on a failure Port B will be used. Once the
failure condition is cleared on Port A, the source will be switch back to
this. (Reverting)
Port B
Port B is the default port and on a failure Port A will be used. Once the
failure condition is cleared on Port B, the source will be switch back to
this. (Reverting)
10.1.5.2
Port configuration
When adding a source the default is that the multicast is configured by be received on both
input interfaces on the input card, i.e both Port A and Port B. These defaults may be overwritten
by editing the input. The following seamless specific attributes is shown in figure below.
Page 257 (306)

it.
This option can be used to use Input Redundancy for multicasts from
different sources. When in this module, the resulting stream will not be
seamless.
The switching time when ‘No bitrate’ on the main port is 100ms.

DMG 3200/3100/3000 – User Manual
10.2 Internal Redundancy
Internal redundancy refers to the process by which a QAM, ASI, IP Output modules, can
receive configuration from two different MMI boards, but not at the same time. This section
describes internal redundancy for these cards in detail.
The chassis will have two switches/MMI modules. One switch will be configured as the main
switch while the other switch will be configured to be the redundant switch. Please note that
internal redundancy configuration is currently only supported for IP input modules, ie Switch+IP
or IP Input.
10.2.1 Dual backplane configuration
The figure below shows the signal flow within the unit when having two backplanes, one MMI
card connected to backplane 1 and second MMI card to backplane 2 respectively.
Figure 10.7- Signal Flow within a Unit with Two Backplanes
10.2.2 Hardware Requirements
The following hardware is required to implement internal redundancy, either:
Two Switch management cards and Two IP input modules
or
Two Switch + IP modules
In addition, one or more output modules are required to implement internal redundancy.
10.2.3 Configuring Modules for Internal Redundancy
Configuring internal redundancy is done by selecting Redundancy  Internal in the Navigation
Pane. This will load the configuration page displayed below.
Page 259 (306)
DMG 3200/3100/3000 – User Manual
Figure 10.8 - Internal Redundancy
There are three sections on the Internal Redundancy configuration page:
This MMI card – displays the status of the MMI module in the chassis. This section is used as
an indicator for MMI correlation. MMI correlation is needed to get rid of the card missing alarms
on the spare MMI module. The status of the MMI module depends on which backplane it is
logged in to.
Twin MMI card – displays the status of the Twin MMI card linked to this chassis, if there is one.
The IP address of the redundant MMI module is used to notify the internal redundancy GUI
about the module. This other MMI module is referred to as Twin MMI. Once a Twin MMI is
added, both MMI modules will exchange their module list; all other configuration must be done
separately on each MMI module.
Internal redundancy supported cards – displays a list of modules on which internal
redundancy is supported, along with the service name (or number of services for QAM output
modules), status, and switching delay. If internal redundancy is not enabled, the service name
value is off.
An alarm with the message Unable to communicate with TWIN MMI is generated whenever
connection breaks between MMI Input cards.
Enable
The check box must be checked to enable internal redundancy on the
module. Each module can be configured at any time no matter which
backplane it is logged in to.
Slot
The slot in which the module has been installed
Type
The type of module on which internal redundancy is being enabled
Page 260 (306)
DMG 3200/3100/3000 – User Manual
Services
Services currently running on that particular module
Status
The status of the module – whether it is logged into the main MMI or the
Twin MMI module.
Switching Delay
Once the QAM output module meets the described conditions to log in
to the Twin MMI automatically, it still needs to wait a determined period
of time. This switching delay is the number of seconds for the module to
switch connections from one backplane to another. Once the switch
delay time is reached, the module will switch backplanes. If the login
succeeds and the input signal is correct, the video and sound will be
back on the screen.
The minimum value allowed for Switching Delay is:
•
QAM/COFDM output fixed 15 seconds
The default value is 15 seconds. If needed, the same module can have
different Switching Delay values for each backplane. This parameter
can be modified in the MMI even if the module is connected to another
backplane.
This Switch button enables the operator to perform a manual switch
from the GUI. When internal redundancy is enabled, this button will be
available. The module will switch right after the operator clicks the
button – without any Switching Delay.
Manual
Reboot
The QAM Output modules are designed to log into the first available MMI board. They will
always try to login to the Main MMI board first, which is connected to default backplane. But
only during the boot process, if login fails through the default backplane, it will try to connect to
the backup even if internal redundancy is disabled in order to find a MMI to login to.
For the Twin MMI to work properly, it is essential that both MMI modules have
an IP connection.
10.2.4 QAM/COFDM/IP/ASI Output Internal Redundancy
When using QAM,COFDM , IP or ASI Output with internal redundancy the switching will be
triggered with the following alarms/events:
•
No signal
•
No contact with MMI module
If all services configured for the output card stop receiving data, the No Signal alarm will be
raised and the internal redundancy module will switch backplanes. This means that even if the
services configured are not enabled to the output signal of the card, it will switch.
Page 261 (306)
DMG 3200/3100/3000 – User Manual
Another condition that will make the output card switch is when the card looses communication
with the MMI Card. This could happen when the card cannot login to the MMI, when the switch
is not working properly, or when the MMI card has been removed.
Digital Output Switch alarms
The table below lists the alarms displayed as a result of the switch:
Switched, reason: logout
The output module is logged out from the input card that hosts
the MMI – for this module, it also refers to internal link failure.
Switched, reason: No
bitrate
This alarm refers to input stream failure having caused the
switch
Switched, reason:
operator
This alarm refers to the operator having performed a manual
switch
There is a delay of 15 seconds before the alarm appears.
10.3 Output Redundancy
The output redundancy solution provided for the output cards is based on sending state events
to an external switch which can then perform the appropriate redundancy switch. For the IP
output card this event is the OSPF messages and for all other outputs the event is in the form of
an SNMP alarm. This allows external equipment and switches to be configured to switch to a
redundant source when these messages are received.
Figure 10.10 – Output Redundancy Status
10.3.1 Non-IP cards Output Redundancy
For non-IP output modules, when there is an error with the output, the system will signal an
‘Output Faulty’ alarm for the specified output port. This is then read by external equipment using
either the SNMP or SOAP interfaces in order to perform the redundancy switching. It is possible
to configure the following options:
•
Configurable switch and Switchback delay - per card
Page 262 (306)
DMG 3200/3100/3000 – User Manual
•
•
Configurable switch mode (one/majority/all) - per port
Manual triggering of the "output faulty alarm" trigger by disabling the output port.
o For the QAM output card 8 transports is grouped into one Physical port. For this
output all transports must be disabled before the "output faulty alarm will" trigger.
To configure the Redundancy options, select Redundancy  Output and click on the Edit
Slot X button for a particular output module. This will open the Edit Redundancy Options
dialog displayed below:

10.3.2 IP Output Redundancy
The DMG’s “always-on” intelligent redundancy software is a seamless integration between
broadcast equipment and IP networks; providing unmatched reliability of service up-time using
the minimum amount of operating resources possible.
The IP output redundancy functionality makes it possible to have multiple units with IP output
modules multicasting the same services and letting the network handle data loss.
By adding one or more redundant units with IP output modules, service outage may be
prevented; given the error is an isolated one.
Figure 10.13 - Output Redundancy
The IP output module sends services out as IP multicasts, relying on OSPF and PIM messages
to configure the network. The routers use this information to route the multicasts. The network
automatically detects the presence of more than one route and redundant packets are thrown
away by the routers before they reach the STBs.
A typical scenario is to broadcast a Digital TV service from two locations using the same
multicast destination address. The network is designed to route only one copy of the multicast
stream to the receiver. In case of a source failure, with IP output redundancy implemented, the
network should automatically switch to the spare source.
By assigning the same (Source, Group) address from the virtual segment for the “main” and
“backup” service the routers regard the multicast from the “main” and the “backup” unit as one
multicast origin from the virtual source network and will automatically chose to forward packets
only from the one with the lowest cost. This is important and must be ensured when the unit is
configured.
The output redundancy configuration is split on two locations. The global settings that applies to
an output card, and the per stream settings applied on a particular output.

Global Settings
The global settings are available on the Redundancy->Output page in the GUI and are
configured per output module.
Figure 10.14 - Edit Redundancy Options
Enable OSPF
Enables OSPF routing – checking this box allows the following
parameters to be configured: OSPF Area, MD5 OSPF
Authentication, and Stubby Area.
OSPF is used to update the routing tables in the routers. The
redundancy scheme currently does not support any other
routing protocols.
Provided PIM is not controlled by the Sencore equipment, it is
possible to support multiple OSPF neighbours.
This feature requires the output redundancy license.
OSPF Area
Designated OSPF area
MD5 OSPF
Authentication
Check to enable MD5 OSPF authentication. Following are the
parameters necessary to configure this feature:
•
Key Id – secret keyword version
•
Key – secret keyword
It is possible to have two sets of MD5 keys – the second set is
required to change the key in switch modules.
Stubby Area
Enable this option if the output is connected to a stubby
network
OSPF Metric

DMG 3200/3100/3000 – User Manual
Enable PIM
Enable or disable Protocol Independent Multicast (PIM).In a
PIM enabled environment, each subnet must have a
designated PIM router (PIM DR). Many routers today supports
taking the role as the PIM DR and for those cases the PIM
should not be enabled in the Sencore unit.
For routers that cannot act as PIM DR the PIM should be
enabled in the Sencore unit. In this case the Sencore takes
over the role as the subnet PIM DR. The Sencore PIM DR is
signaling its own multicasts only; hence other sources on the
same network will be time out and become unavailable.
This feature requires the output redundancy license.
RP Point

Enable Mute On Error
Check to enable or disable Mute on Error
Switching delay(s)
Number of seconds to wait before the output is switched to the
backup path, in case of errors.
10.3.2.2
Stream specific settings
When the global redundancy attributes are defined, output redundancy must be enabled for all
outgoing streams. When enabled the output redundancy will monitor the stream status and if
any errors perform the appropriate action.
Depending on the configuration, the results of an alarm trigger would be:
•
Send an OSPF to the next hop router and announces that the source is no longer
present.
o
o
•
Note that the multicast will still be transmitted.
Note that in a multicast system it is the source that is disabled, which means if
multiple outputs are given the same source address then both/all streams
will be regarded stopped by the router.
Mute the output, ie 0 bitrate, when ’Mute On Error’ is enabled
Page 267 (306)
DMG 3200/3100/3000 – User Manual
Figure 10.15 – Output Redundancy Port Settings
The Port Settings parameters have been described in detail in Section 7.4.
The following Output Redundancy parameters are available:
Source IP
When OSPF is used the source IP should be defined.
If not set then the IP address of the Dataport will be used for all
streams. The effect that a single stream failure will disable all
sources.
The Source IP address set here should correspond to the Source
IP address of the other stream source.
Output Redundancy
The output redundancy logic may decide to stop an output due to
some conditions. One reason could be that a service failed to be
descrambled. If this service is the only service being transmitted on
an output the choice is simple: the system can easily just stop the
output.
On the other hand, if the output is an MPTS containing 10
services, for example. Then the choice is not so simple should one
failure result in all 10 services to be stopped on the output.
The redundancy control option lets the operator decide which
conditions should be met in order for the output to be stopped.
Choose one of the following options:
All – all services must fail
Majority – only majority services must fail
One – one service failure is sufficient
None – automatic redundancy is disabled
These switching rules apply to the services with the highest priority
ranking within the Output TS.
For more information about service priority, refer to the service
configuration property page.

DMG 3200/3100/3000 – User Manual
10.3.2.3
Mute on Error
Mute on Error is a form of output redundancy, apart from OSPF, where the output is disabled if
there is an error with the input stream. This feature can be used in situations where the
equipment receiving the signals require an incoming bitrate of zero (no bitrate), so that a switch
to a backup service or input can take place.
To enable or disable Mute on Error, use the check box in the Edit Redundancy Options dialog
.This feature must also be enabled or disabled for each port on the IP output settings.
The Mute on Error functionality does not require the ‘Output Redundancy’ license.
Enabling Output Redundancy on ASI-Cloned output module and ASI output
modules enables Mute on Error by default.

10.4 N+m Module Redundancy
The N+m Module Redundancy protects the system against possible hardware failure for
selected card types. Module redundancy is currently supported by the following modules:
•
•
•
•
•
encoder-sd
encoder-hd
transcoder-sd
transcoder-hd
Universal Transcoder- Multiscreen Universal Transcoder- Broadcast
Before the redundancy will take effect the user must specify which cards should be part of a
redundancy group and which of them shall be active/main devices and which should be spare
devices.
For the encoder switching an external SDI switch is required. This switch will be configured and
managed by the unit hence no external management system is required. For details on
supported SDI Switches, please contact the Sencore Support department.
All redundancy configurations are performed from the Redundancy->Card navigation pane.
The Card page configures the general group settings while the switch page defines external
switches.
Figure 10.16 – Redundancy group configuration.
The system will automatically populate the internal modules into groups based on the module
type. In the figure above it shows the “encoder-hd” and “transcoder-hd” groups.

even when this device is switched to a spare. The system will automatically redirect any editing
of the spare card to the main card when the spare is running as a backup.

10.5 MMI Redundancy
MMI Redundancy is designed to protect the system from MMI card hardware failures. In case of
an MMI card failure the system shall switch to the backup MMI card in slot 17.
MMI Redundancy will also automatically synchronise the configuration database between the
two MMI modules.
The following cards support MMI Redundancy:
•
•
•
•
•
•
•
•
•
Seamless IP Input
IP output
Dual IP Clone output
Encoder (SD/HD)
Transcoder (SD/HD)
ADM
ASI OUT
Universal Transcoder- Multiscreen
Universal Transcoder- Broadcast
The two MMI cards must be able to communicate in order to synchronize the database.
Currently this is performed via the external management port on the two MMI cards.
Figure 10.31 – External link to two MMIs.
10.5.1 MMI Redundancy Configuration
In order to configure MMI Redundancy, the Switch module must first be changed to this mode.
This is configured in the Maintenance Center and you can find details on this procedure in the
Upgrade Guide.
Once configured, the GUI page for MMI Redundancy will replace the Internal Redundancy
page. This page will be slightly different depending on which MMI the user is accessing. We will
refer as 'Main MMI' for MMI on Slot 0, and 'Backup MMI' for MMI on Slot 17.
Page 279 (306)
DMG 3200/3100/3000 – User Manual
The configuration for MMI Redundancy is available under the Redundancy -> MMI page in the
GUI.
Figure 10.32 – Twin MMI IP address configuration
First the twin MMI IP address must be set, as MMI Synchronizer works based on an external
Ethernet connection between both MMIs.
The 'Card status list' shows all cards that are currently logged in and their status. After setting
twin MMI IP on both MMI modules, you will see the following new rows available for
configuration on the main MMI page:
Page 280 (306)
DMG 3200/3100/3000 – User Manual
Figure 10.33 – Enable MMI Redundancy
After setting both twin MMI IP addresses, all slave modules will be logged into the same
backplane, so this list will show all cards as "Logged in" in one MMI, as "Logged in to twin" in
the other MMI.
Finally, after enabling MMI Redundancy, we will get the complete MMI Redundancy GUI page:
Main MMI
Page 281 (306)
DMG 3200/3100/3000 – User Manual
Figure 10.34 – MMI Redundancy settings-MAIN MMI
Following are MMI Redundancy Settings parameters:
Enable
This is the checkbox to enable/disable MMI Redundancy.
Enabling means both auto config database synchronization and
auto backplane switching for all cards when they lose contact
with MMI.
MMI Redundancy mode
Either of one: Once or Reverting.
Switch delay
This is the delay before a module switches backplane when
MMI switch has been triggered. It is not applied when Manual
Switch is performed.
Switch back delay
This delay is until now only applied on Reverting mode, working
right now only for Alarms trigger.
Page 282 (306)
DMG 3200/3100/3000 – User Manual
Following are Manual operations parameters:
Force manual switch
This will perform an immediate MMI switch.
Following are Status parameters:
Last successful
synchronization
This shows the time last a synchronization was confirmed.
Last local change
This shows the time last local change in configuration was
introduced.
MMI Status
This displays whether the MMI module is currently active or spare.
Synchronization status
Shows the current status:
'Automatic MMI synchronization is active' - Currently no issues
'Unable to automatically synchronize MMI configuration' – Possible
issues with synchronization
10.5.2 MMI Switching Criteria
There are three possible triggers that will perform an automatic MMI Switch:
•
Alarms: There are two alarms which will trigger MMI switch. They can be checked in
'Triggers' node under 'Redundancy' tree in the left panel of the GUI, in 'Card
redundancy' for 'switch' card
•
•
Link down
No contact with FPGA
•
Slave modules lose contact with MMI (MMI dead, reboot, upgrading): All slave
modules monitor the connection to the MMI module and can switch if this is lost. All have
been configured to have this logout trigger enabled with the same delay, so they will
switch at the same time
•
Manual: Twin MMI is forced to take over and all cards are switched to the other
backplane/MMI.
10.5.3 Configuration Database Synchronization
Database synchronisation will be performed automatically in both directions, ie main MMI ->
backup MMI and backup MMI -> main MMI. Immediately after introducing a change in the
configuration on either MMI, it will be synced to the twin MMI.
MMI's IP interfaces will never be synchronised, however, the IP addresses of the other
interfaces on all slave modules will be synchronized.
10.5.4 Link between MMIs
MMI Redundancy is highly dependent on external link between MMI modules. Link down state
is notified to the user as an "Unable to communicate with Twin MMI" critical alarm, and there
are important consequences on this feature if the link is down:
Page 283 (306)
DMG 3200/3100/3000 – User Manual
•
•
•
•
Database synchronization will not be available. This will be shown on Synchronization
status.
The mechanism to enforce all modules to be logged into the same backplane will not
work, as each MMI has no information about the other.
Cards logged into one MMI will not be shown on the other. This will be shown as 'Not
present' and 'Card missing' alarms.
No switch will be available as the mechanism to move modules from one side to the other
is not working.
When the link is restored, and Main MMI is running properly, there are two possible situations:
•
•
There is no MMI switch registered, so there is no reason to stay in Backup MMI. All cards
will be forced to switch back and Main MMI will be Active again.
There is a MMI switch registered. This means either manual or automatic (triggered by
alarms) MMI switch was performed before losing contact with twin MMI (link down). In
order to keep the former state, cards will stay in the second backplane and Backup MMI
will be Active.

DMG 3200/3100/3000 – User Manual
10.6 Conditional Access (CA) Redundancy
The unit supports CA redundancy, in other words, ECMG and EMMG redundancy. The
difference between ECMG and EMMG redundancy is that ECMG redundancy is actively
controlled by the unit, whereas EMMG redundancy is simply allowing for multiple EMMG IP
addresses to connect to the same port.
10.6.1 ECMG Redundancy
ECMG redundancy involves two ECMGs: one Main and the other Backup. If the connection to
the Main ECMG is lost, the multiplexer will automatically switch to the Backup ECMG based on
the configuration defined in the GUI.
ECMs cannot be defined specifically for the Backup ECMG; instead they are automatically
generated according to those defined for the Main ECMG.
In terms of alarms:
When the connection to the Main ECMG is lost, a warning alarm will be displayed in the GUI.
When the multiplexer switches to the Backup ECMG, the earlier warning alarm disappears; it is
replaced with another alarm indicating that a switch has occurred.
Connection to the Backup ECMG is only established at the time of switching. In other words, if
the Backup ECMG fails while the Main ECMG is still running, no alarm will be triggered.
Switching between the Main ECMG and Backup ECMG does not affect the
service as the CW will not be changed in the stream until a new ECM is received
from the ECMG.
10.6.2 Redundancy Configuration
A redundancy rule for ECMGs can be defined from the Redundancy  CA tab in the
Navigation Pane. Insert appropriate values here and click Add.
Before defining the rule, it is necessary to define the Main ECMG from Conditional Access 
SCS  ECMG.
Page 285 (306)
DMG 3200/3100/3000 – User Manual
Figure 10.35 - Setting up ECMG redundancy
The following information is displayed:
IP
Backup ECMG’s IP address
Port
Backup ECMG’s TCP port
Channel
SimulCrypt channel ID for the Backup ECMG
CAS Sub Id
CA vendor specific Sub ID
10.6.3 Manual Switching
Based on Figure 12.8, click Switch. The State value (Running, Sleeping) should change
accordingly.
10.6.4 EMMG Redundancy
When defining the EMMG, it is possible to state its IP address, otherwise known as IP Filter.
Specifying an IP filter prevents unknown EMMGs from connecting to the Scrambler module.
Page 286 (306)
DMG 3200/3100/3000 – User Manual
Figure 10.36 - Setting up EMMG redundancy
However, it is not compulsory to add this IP Filter. Using the value 0.0.0.0 ensures that the
EMMG connection will not validate the Source IP address (of the EMMG). In addition, multiple
sources may connect to the same listening port, but not concurrently.
If a Main and a Backup EMMG are present in the system, the first EMMG to connect will be the
active one. A connection from the second unit will be rejected as long as an EMMG is currently
active.
It is not possible to manually switch the EMMGs as this connection controlled
by the EMMG itself.
11 Control And Monitoring

11.1.6 Alarm Setup
The alarm setup feature enables operators to customize their alarms either by setting a
preferred severity (overriding the default level of severity) or filtering the alarm.
Slot
Lists all modules with their corresponding slot numbers in brackets
Port
Allows for selection of a particular port, depending on the module selected
under Slot.
Alarm
Lists all possible alarms for the selected module in Slot. These alarms are all
registered by each module in the system. If no specific module is selected, all
alarms are listed.
Action
There are five possible options here:
• Set severity: Notify – Overrides the alarm’s default severity to Notify
• Set Severity: Warning – Overrides the alarm’s default severity to
Warning
• Set Severity: Major – Overrides the alarm’s default severity to Major
• Set Severity: Critical – Overrides the alarm’s default severity to Critical
• Filter – Filtering is based on slot, port and alarm type. If an incoming
alarm does not pass the filter, the alarm is discarded. In other words, the
alarm is not visible in the Active Alarms node, not recorded in Alarm
History, and not indicated on the LED of the module itself.
The alarm filter page lists all the relevant alarms for the card type selected (if no specific card is
selected all alarms are listed). When an alarm filter is removed any active alarms which are
filtered will re-appear with the timestamp according to when the filter was removed.
The alarms shown in the alarm drop down list are all alarms registered by each module in the
system. A module is most often represented by a card. When an alarm is raised by the
respective module detecting an error condition it is possible for the module reporting the alarm
to override the alarm description, in order to add some extra information.
In some cases, this may cause the alarm text displayed in the alarm filter not to match the
actual alarm text; but it should be obvious which alarm it is.
The Alarm Filter also applies for the SNMP trap system.

Figure 11.10 – An alarm with specific alarm description
11.1.7 Root Cause Filter
The root cause filter removes alarms which are caused by alarms earlier in the streams, hence
eliminating distracting alarms. It is turned on and off in the Alarm Setup page.
11.1.8 Monitoring Setup
Raise alarm for scrambled inputs in IP input ports in below of following condition selected by user.
Figure 11.11– Monitoring Setup page
These are the following options supported:

DMG 3200/3100/3000 – User Manual
11.2 SNMP
The SNMP agent is located on the MMI module, and uses the same IP address. A number of
variables can be configured, including the SNMP configuration file (containing the public and
private community strings, for user access and alarms); and the trap destination table. This is
explained below.
11.2.1 Configuration of SNMP Alarm Filter via the GUI
The ordinary alarm filter and the root cause filter is before the SNMP filter, and any alarms
which are filtered away by those mechanisms, and hence are not shown in the active alarm list,
are never sent via SNMP.
Figure 11.12 – Five Trap Destinations and the Alarm Filter can be set in the GUI.
The SNMP alarm filter provides filtering based on slot, port and alarm ID, like the Alarm Setup
before it, and it is operated the same way.
11.2.2 Configuration of SNMP Trap Destination Table via the GUI
Five different trap destinations are set in the GUI. After changing status, or IP address or
community, press Apply to start forwarding alarms.
11.2.3 Configuration of Trap Destination Table via SNMP
The trap destination table must be edited to receive traps. It has five entries, hence allowing five
different trap destinations to be used at the same time. Additional rows cannot be created. The
tdIpAddr field contains the IP address of the NMS, while the tdRowStatus field is used to
determine whether traps should be forwarded. To enable traps towards a specified address the
corresponding tdRowStatus field must be set to active (1). To disable traps, set the
tdRowStatus field to notInUse (2). Errors are reported when trying to send traffic towards IP
address 0.0.0.0, which is the default IP address.
11.2.4 Interpretation of Traps
Each trap is uniquely identified with the combination of msgId, msgSlot, msgPort, and
msgInstance fields. The type of error is specified with the msgId field, while the location is
Page 296 (306)
DMG 3200/3100/3000 – User Manual
specified with the rest, where the msgSlot field is the slot, msgPort is the port on the slot, while
the msgInstance field is used when further differentiation is necessary.
The other fields correspond to the fields in the GUI: the msgSeverity field to Level, the
msgSourceName field to Application, the msgText field to Error Code, and the
msgGenerationTime field to Set.
For more information on using the SNMP agent, refer to the SNMP Integration
Guide.
11.3 SOAP XML Interface
The SOAP XML interface can be used for external control and monitoring of the unit. For more
information on the SOAP XML interface, refer to the Sencore SOAP XML API document.
12 Maintenance
This chapter describes how to perform maintenance tasks such as software upgrades,
replacing faulty modules, etc.
12.1 Software Upgrades
Software can be uploaded to the unit remotely using the Maintenance Center (MC) available on
port 8088 of the unit, ie http://<ip_addr>:8088/. Refer to the Upgrade Guide for details.
Required software upgrades for the units will be provided together with instructions by
Sencore’s support department.
For more details on the upgrade procedure, please refer to the Upgrade Guide document.
12.2 Hot-Swapping
The platform supports module hot-swapping, i.e. the different modules – power supply, fan,
input, or switch – can be replaced when the head-end is in operation, without shutting it down.
In other words, removing a module and replacing it with a new one will not damage the module.
The effects of hot-swapping a module are explained in further detail in the following sections.
12.2.1 Performing a Hot-Swap
To remove a module, first loosen the screws on the top and bottom (one screw is located in the
ejector). Next, press the white button inside the module ejector and push the ejector down. The
module is now released from the chassis.
To insert a new module into the chassis, it is important to align the module’s edges with the
module-guides in the chassis. Ensure that the jack on the module is in the open position as
illustrated in the figure below. Slide the module into the unit on the module-guides until the jack
touches the chassis. Move the jack upwards. This will insert the module all the way into the unit.
Page 297 (306)
DMG 3200/3100/3000 – User Manual
12.2.2 Switch+MMI Module Hot-swap
This module manages all the other modules in the unit and stores all configuration information
in a database. Replacing the Switch+MMI card will cause all services to stop. Hence
replacement of the MMI board must be performed with care, and a full backup of the
configuration database is recommended.
All communication between different modules in the unit is facilitated by the switch-module;
removing this module will disable all backplane communication resulting in loss of all services
(the color of the status LED on the modules will change to blue).
Once a replacement switch card is inserted into the device the LED will change back to red or
green and services will resume automatically.
Figure 12.1 - A Module with its Ejector released
12.2.3 Other Module Hot-swap
Modules can be replaced during normal operation with minimal disruption of services, affecting
only the relevant modules. The unit will automatically reconfigure the new module with identical
values its predecessor. Therefore, the module will automatically begin descrambling the same
service descrambled previously.
It is important to insert the new module into the same slot as the previous one;
and ensure that their configuration is identical.
12.3 Adding, Replacing, or Removing Modules
Before upgrading a unit with additional modules, ensure that there is sufficient space (slots) in
the chassis.
Page 298 (306)
DMG 3200/3100/3000 – User Manual
When all the new modules have been inserted into the chassis, make sure that the front of the
chassis is completely closed with the front panels. Leaving a slot position open without a
module or front panel will cause the unit to draw false air and consequently result in overheating of the modules in the chassis.
To permanently remove modules from a specific slot position, the modules should first be
removed from the chassis. Next, go to the About page from the Navigation Pane. Click to
remove the modules. Modules flagged for removal will be crossed out. Click again to deselect
a module. Finally click Apply Changes to permanently remove the configuration of the module
from the chassis.
When replacing an existing module, note that a module configuration always follows the slot
position and not the module itself. Consequently, if a module is moved from one slot in the
chassis to a new slot, the unit will report the original slot position as hardware missing, while the
new slot position will be configured as a new module with default configuration. Hence if a
module is to be replaced it is important that the same slot is used.
When replacing a module with a different module type, a mismatch will occur. This will be
shown both in the alarms and in the About page. A DVB-S/S2 module however, can replace a
QPSK module. When this happens, a convert button will show up in the About page along
with the remove button. Clicking this button will enable the DVB-S/S2 module to inherit the
configuration of the old QPSK module.
It is not possible to undo this process from the web GUI.

12.4 Importing and Exporting Chassis Configuration
The configuration of a unit can be saved onto a file to be retrieved later. This file contains the
entire configuration, including the MMI IP address. To save the current configuration, click
Export (see Figure 14.3).
To retrieve the configuration from an existing file, select the file by clicking Browse. Then, check
Include local IP addresses if the IP addresses should be included, and click Restore.
Figure 12.2- Saving Importing and Exporting Chassis Configuration
This feature has two benefits:
o
o
To restore a unit to a previous state, or
To use the same setup on multiple units
Use the Include local IP addresses option to bring a unit back to a previous state when lots of
changes need to be undone; or if an upgrade has been unsuccessful.
It is recommended that the configuration be exported before each upgrade and restored after a
downgrade (if the downgrade was unsuccessful).
To use the same setup on multiple units, uncheck the Include local IP addresses option. This
way, only one unit needs to be configured, and all the other units will use the same
configuration – but on their existing IP addresses.

DMG 3200/3100/3000 – User Manual
12.5 Restoring the Default IP Address
It is possible to restore to the factory-configured IP address on the Switch+MMI module. This
can be useful if the software-configured IP address is lost. The restore is done by setting dip
switch 2 to ON on the Switch+MMI card. When the setting has been applied, the MMI will be
configured according to the tables below regardless of what is stored in memory.
The default IP settings are:
IP Address
192.168.1.100
Subnet Mask
255.255.255.0
Default Gateway
192.168.1.1
After setting the DIP switch the MMI card has to be rebooted. The factory default IP settings will
be active as long as the setting is present. While the DIP switch on, all IP parameters in
memory can be changed and saved via the web interface. Once the DIP switch is changed
back to OFF and the card is rebooted, the IP settings in memory will be activated.

12.6 Restoring the Default IP Address for 1RU (3200).
12.6.1 Resetting IP address using USB Cable
The Switch+MMI module control can be accessed via Ethernet over USB. A USB A/A cable
(standard-A type connector in both ends) should be connected between a PC and the MMI
module.
To access the MMI a driver for RNDIS Ethernet gadget must be installed.
On a Windows PC the driver can be installed automatically over Windows Update, or it can be
downloaded manually. The Switch+MMI module can then be accessed directly from a web
browser, using the IP address 169.254.254.254.
All MMI functionality is supported over this interface.
12.6.2 Resetting IP address with DIP switch:
It is possible to restore to the factory-configured IP address on the Switch+MMI module. This
can be useful if the software-configured IP address is lost. The restore is done by setting DIP
switch 2 to ‘ON’ on the Switch+MMI card. When the setting has been applied, the MMI will be
configured according to the tables below regardless of what is stored in memory.
The default IP settings are:
IP Address
192.168.1.100
Subnet Mask
255.255.255.0
Default Gateway
192.168.1.1
After setting the DIP switch the MMI card has to be rebooted. The factory default IP settings will
be active as long as the setting is present. While the DIP switch on, all IP parameters in
memory can be changed and saved via the web interface. Once the DIP switch is changed
back to OFF and the card is rebooted, the IP settings in memory will be activated.
In order to remove the module, the following procedure must be followed:
1.
2.
3.
4.
5.
6.
Loosen the thumb screws for the fan assembly and remove the fans
Loosen the thumb screws on the MMI module
Press on the Switch-MMI module to come out little.
