Introduction
The DCM is able to burn-in subtitles in the encoded video stream of services. Subtitles can be conveyed in
different forms, teletext base subtitles, bit-map based subtitles, and so on. A DCM with an MFP card supports
bit-map based subtitles as specified by the DVB (Digital Video Broadcasting) subtitling specification. To
configure subtitle burn-in for a video stream, see Using the Subtitle Burn-In Feature, on page 36.
The DCM logo inserter allows you to insert static logos, animated logos, and messages in the video stream
of a service. A message is inserted in a video stream using a banner whether or not accompanied by one or
multiple logos (up to four logos / banner). Inserting logos (without banner) in services uses the logo insertion
feature and inserting banners uses the banner insertion feature.
The logo inserter can also be used for the Emergency Alert System (EAS). When the EAS is activated for a
certain emergency reason (tornado, earthquake, and so on), an EAS alert message is inserted in the video
stream of the services for which EAS is enabled. For more information about the setup of this system, see
Using the EAS Alert Insertion Feature, on page 30.
The logo insertion, banner insertion, and EAS alert insertion processes are done by a Transcoder Card that is
calibrated to a logo inserter or by an MFP. To change the Transcoder Card calibration, see Changing the
Transcoder Card Calibration.

Logo Insertion and Subtitle Burn-in
Licensing
A Transcoder and MFP card have no inputs and no outputs and presenting the video stream must be done by
routing the corresponding incoming service from the card input through the Transcoder or MFP card to the
output of a card. A Transcoder Card is able to process four video services and maximum four logos and one
banner can be inserted in one video stream at the same time. An MFP card is able to insert maximum three
static logos or one banner together with one static logo in a processed video stream at the same time. An MFP
card does not support animated logos.
Important
• Banner insertion and subtitle burn-in by an MFP card is not possible if its MFP Mode is set to
Premium Picture Quality Transcode or Encode.
• For logo insertion using an MFP card, the resource setup of the engine must be set to 6 SD Video,
2 HD Video, 1 Premium PQ HD Video, or 2 Premium PQ SD Video. If the resource setup of an
MFP engine is set to 2 HD Video, logo insertion can only be done in one HD (high definition) video
service. Then, the second slot can no longer be used.
• Inserting logos using a Transcoder Cards needs a card with TC CO-P DSP revision V03.00.00 or
later. The hardware revision numbers can be found on the Version Info page of the DCM GUI
(graphical user interface). See Checking the Version Information.
• A Transcoder Card supports the insertion of static logos, animated logos, and messages in SD video
streams (frame coded only) or HD video streams (frame coded only) with video format 720p (max
60 Hz).
• To achieve a compliant video stream after inserting a logo, banner, or EAS alert, the bit rate of the
video stream must be controlled by adding the corresponding service in a rate control group and
setting the rate control mode to Rate Limited or Stat Muxed. For more information about rate
control, see Rate Control.
Licensing
The logo insertion and the subtitle burn-in features are licensed. See Logo Insertion and Subtitle Burn-In
Licensing.
Using the Logo Insertion Overview Page of a Transcoder Card
For each Transcoder Card that is calibrated to a logo inserter, the DCM GUI provides a Logo Insertion
Overview page with a Logo Inserter Overview table. This table is populated with all the services that are
passed from the input to the output through the logo inserter.
The following table describes the icons in the Service Overview table.

Using Libraries
Logo Library
Before a logo can be inserted in the video component of a service, the logo must be uploaded to the logo
library of the DCM. Instead of uploading a logo, a URL (uniform resource locator) can be specified (remote
logo). When the remote logo is activated for logo insertion, the device downloads the logo from the configured
location.
Digital Content Manager (DCM) Configuration Guide - Software Version 19.10

OL-29584-16
Logo Insertion and Subtitle Burn-in
Logo Library
Note
• Maximum 128 logo configurations (static and animated logos) can be uploaded to the DCM.
• For remote logos, DCM only supports IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol
version 6) address based HTTP URLs (without DNS [Domain Name System] lookup).
◦The format for an IPv4 address must be:
http://<IP>/<Location on remote HTTP server>/<file name>
Or
http://<IP>:<port number>/<Location on remote HTTP server>/<file name>
For example:
http://192.0.2.0:28550/LogoArchive/PNG/default_logo.png
◦The format for an IPv6 address is similar but the IP address must be enclosed in square brackets.
For example:
http://[2001:db8:0:1]:28550/LogoArchive/PNG/default_logo.png
• Limits can be configured to the maximum size of the logos. When a logo is uploaded to the logo
library of the device and the size of the logo exceeds these limits, an Operation Not Succeeded failure
is displayed and the corresponding logo is not added to the library. When a remote logo is downloaded
at the moment a logo insertion is activated and the size of the logo exceeds the limits, the logo
insertion action is aborted and an alarm is generated.
• If a remote logo cannot be downloaded when it must be inserted, or when the remote logo is defined
as static logo and the downloaded logo is an animated logo, or when the logo is corrupt or not
supported by the DCM, the logo insertion action is not executed and an alarm is generated.
• The logo insertion action is executed if a remote logo is defined as animated logo and the downloaded
logo is a static logo.

Routing a Service to the Output Through the Transcoder or MFP
Card
For inserting a logo, banner, or EAS alert in a video service, the service must be passed from the input to the
output through the Transcoder or MFP card. The following topics describe how to pass a service from the
input to the Transcoder and to the output. Next to these topics, the procedures are described to merge particular
components from a service, which is processed by a logo inserter, in an outgoing service.
For logo insertion using an MFP Card, the incoming service must be routed to the output through an engine
of a MFP card and processing must be enabled (Transcode or Encode). See Transcoding Using the MFP Card
or Baseband Video Encoding.

Merging Components from the Logo Inserter in an Outgoing Service
Particular components of a service, which is processed by a logo inserter, can be merged in an outgoing
service.
Note
All components of a service that is processed by a logo inserter have the same processing delay. When,
for instance, audio components from a processed service are merged in an outgoing service that is not
delayed by a particular process, the audio is not in sync.
Merging components of a service, which are processed by a logo inserter, can be done in two different ways:
using the drag-and-drop method or by creating component merge rules.

Using the Logo Insertion Feature
Before a logo can be inserted in the video stream of a service using the logo insertion feature, a logo assignment
must be created for this service. The DCM allows you to assign multiple logos from the logo library to the
video stream of a service.
Restrictions for services processed by an MFP:
• Maximum three logos can be inserted in one video stream at the same time. When you try to insert more
logos in a video stream at the same time, the logo inserted using the banner insertion or the EAS alert
insertion feature has higher priority than the logos inserted using the logo insertion feature.
• The logo must have a rectangle format, a nonrectangle logo must be created using an alpha channel with
100-percent transparent pixels.
• Logo insertion cannot be combined with splicing or ABR.
Restrictions for services processed by a Transcoder Card:
• Maximum four logos can be inserted in the video stream at the same time. When you try to insert more
logos in a video stream at the same time, the logos inserted using the banner insertion or the EAS alert
insertion feature have higher priority than logos inserted using the logo insertion feature.
• The combined frame count of the animated logos cannot exceed 250 frames.
• The total area used by an inserted banner and inserted logos cannot be higher than 25 percent of the
resolution of a 720 pixel frame. When this total area exceeds 25 percent of the video resolution, the last
logos are not inserted.

Logo Assignment
If logos are inserted in a video stream and a banner/EAS insertion is activated, the logos are temporarily
removed. Once the banner insertion is finished, the logos are resumed. A Transcoder Card removes a minimal
amount of the logo, enough to free up the resource for the banner to be displayed. An MFP removes all logos
regardless how much resources the banner needs.
Note
When a banner overlaps other logos, the order from back to front is: video, banner, text, and logos.

with the appropriate information together with one or multiple accompanying logos, indicating the seriousness
of the emergency, in the video stream of services. An EAS alert insertion can be started manually or can be
controlled by an EAS system using the XML interface or SCTE18 protocol.
Caution
When an EAS alert is inserted in the video stream of a service while a banner is inserted, the banner is
removed from the stream and vice versa.

Steps to Take
Restriction: The total area occupied by a banner and logos inserted using a Transcoder Card, is limited. When
this total area exceeds 25 percent of the video resolution, the last logos are not inserted.
About EAS Alert Insertion Controlled by an EAS System Using the SCTE18 Protocol
An EAS alert insertion can be triggered by an EAS system using the SCTE18 protocol. When the DCM
receives an EAS message from an EAS system, the banner of which the name matches the EAS event code
of the message is inserted in the services for which EAS alert insertion is enabled. If no banner matches this
EAS event code, the sample banner of the DCM is used. The text that is inserted in the banner is derived from
the alert text of the EAS message.
Note
• If the DCM receives an EAS message while a banner insertion is active, the active banner is replaced
by the banner with EAS alert.
• If a banner insertion is activated for a service while a banner with EAS alert is active, the active
banner with EAS alert is replaced by the activated banner.
• The EAS alert insertion is not executed if the banner consumes more license keys that available.
• The EAS alert insertion is not executed for a service if the banner, which must be inserted, does not
correspond with the Allowed Banner parameter of the service. For example, if a banner is chosen
with animated logos and the Allowed Banner parameter of the service is set to Static Logos.
• Repeated SCTE18 messages do not trigger additional EAS banner insertions.
• Already processed emergency alerts (identified by the EAS event ID) are not processed again within
a time window of 24 hours. The latter means that after 24 hours, when an emergency alert message
arrives with the same EAS event ID as a previous alert, it is considered as a new emergency alert
message and triggers a banner insertion.
Steps to Take
For Manual EAS Alert Insertion
The following list describes the steps to take to insert an EAS alert manually in services.
1 Route the incoming service to the output through the Transcoder or MFP card. See Routing a Service to
the Output Through the Transcoder or MFP Card, on page 16.
2 Add the logos, which must accompany the message, to the logo library of the DCM. See Logo Library,
on page 4.
3 Create an appropriate banner with logos for the EAS message. See Banner Library, on page 12.
4 Set the EAS Alerts parameter for the services in which the EAS message must be inserted.
5 Start the EAS alert insertion as described in Performing a Manual EAS Alert Insertion, on page 33.

The DCM allows you to process in-band cable emergency alert message (CEAM) packets (labeled with PID:
0x1FFB) and out-of-band CEAM packets (labeled with PID 0xFFC) coming from the EAS system using the
SCTE-18 protocol. The DCM receives the out-of-band packets, carried using UDP (User Datagram Protocol)
data packets, on one of its management ports. To establish connection between the DCM and the EAS system,
an EAS proxy must be created.
Creating EAS Proxies
Procedure
Step 1
In the DCM GUI, choose Configuration > Proxy from the main menu and then click the EAS tab.
The Proxy EAS page appears.
Step 2
Refer to the ADD EAS Proxy area.
Step 3
Step 4
In the EAS Name field, enter a name for the EAS proxy. The name must be unique, spaces and
uppercase/lowercase are ignored.
From the Interface drop-down list, choose the management port that is used by the DCM to establish connection
with the EAS: 10/100, or GbE. When NIC (network interface card) teaming is switched on, the NIC teaming
pair is indicated by Bond 1.
Step 5
From the Type drop-down list, choose the socket type: Unicast, Multicast, or Broadcast.
Step 6
For a Multicast socket type, enter the multicast IP address in the IP field.
Notes:
• The IP box is dimmed for a unicast or broadcast socket type.
• For an IPv6 IP address, use a format as recommended by RFC 5952.
Step 7
In the UDP field, enter the UDP port number.
Step 8
Choose Enabled or Disabled from the Text Crawl drop-down list to enable or to disable the insertion of
EAS alerts if appropriate SCTE18 messages arrive.
Click Add.
Step 9
Note
• The DCM allows you to create maximum ten EAS proxies.
• If a UDP port is already in use on the selected interface (for instance, UDP port 5168 for splicing
purposes), creating an EAS proxy with this UDP port is not possible.

Changing EAS Proxies
Procedure
Step 1
In the DCM GUI, choose Configuration > Proxy from the main menu and the click the EAS tab.
Step 2
In the EAS Proxy Settings table, click
in the row of the EAS proxy that must be changed.
The Configure EAS Proxy dialog box appears.
Step 3
In the EAS Name field, change the name for the EAS proxy.
Step 4
From the Interface drop-down list, choose the management port that is used by the DCM to establish connection
with the EAS: 10/100, or GbE. When NIC teaming is switched on, the NIC teaming pair is indicated by Bond
1.
Step 5
From the Type drop-down list, choose the socket type: Unicast, Multicast, or Broadcast.
Step 6
For a Multicast socket type, change the multicast IP address in the IP field.
Notes:
• The IP box is dimmed for a unicast or broadcast socket type.
• For an IPv6 IP address, use a format as recommended by RFC 5952.
Step 7
In the UDP field, change the UDP port.
Note: Changing the UDP port to a port that is already in use is not possible.
Step 8
Choose Enabled or Disabled from the Text Crawl drop-down list to enable or to disable the insertion of
EAS alerts if appropriate SCTE18 messages arrive.
Click OK.
Step 9
Removing EAS Proxies
Note
Deleting an EAS proxy that is in use as CEAM source in an outgoing TS is not allowed.
Procedure
Step 1
In the DCM GUI, choose Configuration > Proxy from the main menu and then click the EAS tab.
Step 2
In the EAS Proxy Settings table, click
in the row of each EAS proxy that must be removed.

Using the Subtitle Burn-In Feature
Hint: After clicking and the Delete Confirmation on Single Click Delete option is enabled, a confirmation
box will be displayed. Click OK to confirm.
Using the Subtitle Burn-In Feature
The subtitle bit-map stream is encapsulated in an elementary stream that is part of the service. The elementary
stream can carry the payload of multiple subtitle bit-map streams each associated with a language or each
subtitle bit-map stream can be encapsulated in a separate elementary stream.
The subtitle elementary stream for a service is referenced in the PMT (program map table). The information
about the subtitles (language) is indicated in the branch of the incoming elementary stream (0x06) on the Tree
View page.
For subtitle burn-in, transcoding must be enabled for the corresponding video stream.
Important
• The MFP must receive the subtitles at least 400 ms before burning in. The subtitle spacing must be
equal to or greater than 400 ms.
• If the same language is present multiple times in the same elementary stream (for instance, normal
and hearing impaired subtitles), the normal subtitles are burned in.
Restrictions:
• Subtitle burn-in cannot be combined with logo insertion for the same video stream.
• Subtitle burn-in cannot be combined with splicing and cannot be used for multires profiles.
• Subtitle burn-in by an MFP card is not possible if its MFP Mode is set to Premium Picture Quality
Transcode or Encode.
• For subtitle burn-in, the mode of MFP card must be set to High Density Transcode. When the resource
setup of an engine is set to 6 SD video, the engine is able to burn in subtitles in two video streams. The
other SD slots can then be used for other processes. When the resource setup of an engine is set to 2 HD
Video, subtitles can only be burned in one video stream. The second slot can no longer be used.
