General
The ¸DVM 400 is a highly compact,
portable MPEG-2 platform that offers a
wealth of test, analysis and ­monitoring
functions for digital TV. Users require
neither a laptop nor an external ­monitor
to operate the system since it comes
equipped with an integrated, highresolution color display. The system is
operated by means of its keys and rotary
knob, or via the supplied USB mouse. An
external monitor and keyboard can be
connected. Versatile options ensure that
customer requirements are optimally
­satisfied. Functions can usually be added
simply by installing a software key.
The ¸DVM 400 includes a ­powerful
computer platform with various
­interfaces and space for three plug-in
cards. A broadband recorder and generator board can be installed in the first
slot. A fast analyzer board as is used in
other ­systems of the ¸DVM ­family is
a­ vailable for the second slot. This board
allows parallel monitoring of up to four
transport streams. Since both boards
­function independently of each other, the
¸DVM 400 can be configured either
as a pure recorder and generator or as a
pure analyzer. If both boards are ­installed,
special features are available. For
­example, a recorded signal can be sent
directly within the system to the analyzer
board for later analysis. Or, if a signal is
monitored, the analyzer board can directly
trigger the recorder and generator board
to perform event-driven recording.
Various test signals are available for
the recorder and generator board. By
using the Stream CombinerTM software,
users can generate their own transport
streams on the ¸DVM 400.
Like the ¸DVM 100, the
¸DVM 400 can be expanded by the
¸DVM 120 to monitor more than four
transport streams; parallel monitoring
of up to 20 transport streams is thus possible via the GUI of the ¸DVM 400
(two ¸DVM 120 plus options are
required).
Both boards support a variety of
­functions, some of which are optionally
available. The analyzer board allows not
only transport stream monitoring, but
also the analysis of data rates, PCR and
PTS values, the interpretation of tables
and packets plus the analysis of diverse
data services.

Monitoring and analysis
­functions
The figure below shows a block diagram
of the analyzer board that is used for the
monitoring and analysis functions of the
¸DVM 400.
Up to four transport streams can be monitored in parallel. One transport stream can
be monitored with the analyzer option,
another three with one ¸DVM-K1
­option each. In addition to the monitoring
functions, numerous analysis functions
are available. Analysis can be performed
on one of the transport streams at the
same time it is being monitored.
Monitoring functions
Transport streams are monitored
in ­accordance with Measurement
Guidelines TR 101290. Well over
100 ­parameters are monitored on each
transport stream, including:
◆ All first, second and third priority
­parameters (with the exception of
3.3, buffer)
◆ Bit rates of all transport stream
­elements (different ­calculation
­methods in accordance with
TR 101290 can be selected (MGB1,
MGB2 and MGB5 with τ = 5 s))
◆ Availability and contents of the
megaframe initialization packet (MIP),
used in single frequency networks
(SFN)
◆ Modification of conditional access
information
◆ Transport stream modifications (TS ID,
addition or omission of elements, etc)
result display, the user assigns each
­measurement parameter to one of the
three ­following classes:
◆ Alarm
◆ Warning
◆ Information
If an (error) event is detected, it is
­displayed along with its associated
class. All events are compiled in a report
that can fast and easily be sorted and
­filtered on the basis of diverse criteria.
Moreover, there is an error counter for
the individual parameters, providing a
quick summary of the frequency of individual errors. The data and table refresh
rates are clearly presented by means of
graphical displays. The use of symbols to
indicate different classes of errors makes
it possible to quickly determine the current status.
The limit values of all measurement
parameters can be set. Individual
parameters can be excluded from monitoring so that no unnecessary messages
are generated for known or accepted
errors. To obtain a straightforward

Event navigator
As a special feature, the ¸DVM 400
supports filter functions for the report
entries which can be easily selected by
clicking the right mouse button. It is thus
possible to quickly detect:
◆ All entries for a PID (e.g. all entries
for PID 100 (e.g. video))
◆ All entries of the same type (e.g. all
entries for an incorrect PMT repetition period)
◆ All entries for a PID of the same type
Moreover, all entries can be filtered on
the basis of their classification (alarm,
warning and information).
Analysis functions
Each analysis function can be performed
at the same time transport streams are
being monitored.
In-depth analysis
PCR jitter: For comprehensive measurement of PCR jitter; selection of one
of the two measurements “Overall” or
“Accuracy”; setting of the filters used
(MGF1 to MGF3) also for monitoring;
measurement and filter characteristics
as defined in TR 101290.
Application example for the event navigator
SI/PSI table interpreter: Detects a
­corresponding section in the TS and
­interprets its contents.
PES header interpreter: Lists all header
elements of a selected PES and interprets their contents.
TS packet interpreter: Displays a transport stream packet in hex format and
simultaneously as an interpreted list of
contents for the header and adaptation
field.
Header map: Provides an overview of
the packet distribution of individual
­elementary streams; displays the first
four bytes of each transport stream
packet in hex format.
PCR distance: Graphical representation
of the distance between individual PCR
values of a program.
PTS/PCR difference: Graphical representation of the difference between PTS
and PCR.
PTS distance: Graphical representation
of the distance between individual PTS
values of a program.
All measured PCR and PTS values are
displayed as traces. Up to one hour of
data can be displayed. Zooming within
the display is no problem. The figure on
the right shows an example of a PCR
measurement.

Data broadcast analysis
A wide scope of analysis functions is
available for data broadcast applications.
The ¸DVM400-B1 base option alone
provides the following functionalities.
All transmission techniques and related
applications listed below are recognized
and entered in the transport stream
­elements list under the appropriate
­designation:
◆ DVB object carousel, e.g. for downloading of MHP applications
◆ DVB data carousel, e.g. for system
software updates (SSU)
◆ Multiprotocol encapsulation (MPE),
e.g. for IP data transmission
◆ Data streaming, e.g. for teletext, subtitles, VPS, WSS and transmission of
personal data
◆ Data piping, e.g. for transmission of
personal data
The following tables are also listed:
◆ Application information table AIT
(MHP)
◆ IP/MAC notification table INT
(IP data via MPE)
◆ System software update notification
table UNT (SSU)
The data broadcast analysis option
­significantly enhances the scope of
­functionalities.
Another view can be selected in the GUI.
The corresponding section is highlighted
in red in the figure below.
The bit rates of a data service can also
be measured by means of the associated PID.

The two views “Protocol“ and “Content“
are especially useful for more complex
data transmission methods such as MPE
and object and data carousel. The figure
below shows an example of an object
carousel.
These two views have the following
functions:
◆ “Protocol”: displays the transmission
element structure
– Example: data/object carousel: DSI,
DIIs, DDBs organized in groups and
modules
– Example: IP data via MPE: number
of sections per MAC address
◆ “Content”: displays the content

Wizard
This powerful feature makes the use of
the different analysis tools highly effective and easy. Once a transport stream
element has been selected, the wizard
suggests all analyses and measurement
result views that are useful for this element, allowing fast and detailed analysis especially when an error has been
detected. The wizard is ideal for less
experienced users because it enables
them to easily obtain correct measurement results.
TS capture function
This option (¸DVM-K2) makes it
possible to continuously buffer up to
384 Mbyte1) of transport stream data
in RAM. An event can trigger backup
of transport stream data to the system
hard disk. This event may be an error
­detected by the analyzer board or when
the user starts recording. This function
can be configured in such a way that it
waits for a new event once the data has
been saved. The stored files are automatically numbered.
1)
Generation of seamless and endless
transport streams
The recorder and generator board allows
the generation of endless and seamless
transport streams. For this purpose, the
TS generator base option contains an
­extensive collection of transport streams
in the Rohde & Schwarz GTS format.
This function can also be started for all
four transport streams of an ­analyzer
board simultaneously. In this case,
96 Mbyte are available for each transport stream.
The ¸DVM-K2 option is designed
specifically for storing incorrect transport stream sections during analysis or
transport stream monitoring. If a large
amount of data is involved, the recorder
and generator option can be used to
­record and replay it.
The transport streams generated from
the RAM meet all requirements specified
in the section “How to generate a transport stream in a seamless endless loop”
(page 9). The following characteristics
are additionally provided:
Recorder and generator
functions
◆ Jitter of the PCR values (waveform,
frequency and amplitude can be set)
◆ Selectable data rate (up to 214 Mbit/s
by inserting null packets)
◆ Transport stream generation in GTS
format with user-specific contents
(both elementary stream contents as
well as PSI/SI/PSIP contents (option
Stream CombinerTM ¸DVG-B1)
The figure below shows a block diagram
of the recorder and generator board
used to record, replay and generate
transport streams.
For systems delivered as of May 2004 (systems delivered prior to this date feature 128 Mbyte (32 Mbyte with four transport streams)); expansion possible through

Test signals
The TS generator option comes with a
variety of different preconfigured MPEG-2
transport streams that are compliant with
the ATSC and DVB standards and can be
accessed at a keystroke.
These transport streams consist of several elementary streams and ­contain video, audio and other data (e.g. teletext or
PRBS). Video streams with different data
rates, formats, ­frequencies and contents
are available.
The signal set comprises sequences
with moving picture contents as well
as static test patterns. The test patterns include color bars, zone plate,
CCIR17/18/331, ITS1 to ITS4, etc, and
the Rohde & Schwarz codec test pattern.
Due to integrated test lines in the upper
and lower picture area of this test pattern, the codec signal can be utilized to
measure the analog outputs of a set-top
box (or IRDs) within a few seconds by
using a suitable video analyzer such as
the ¸VSA.
In addition, integrated moving ­picture
elements allow the function of the
decoder to be checked visually for any
problems. Audio data streams with different sampling rates, encoded in line
with MPEG-1 layer 2 or Dolby AC-3,
contain the accompanying sound for the
video sequences as well as special audio
test signals. Of course, the transport
streams include all program information,
service and system tables (PSIP or SI)
required by MPEG-2 and ATSC or DVB as
stipulated by the selected standard.
Further options enable HDTV signals and
other special test signals to be added
to this large collection (see HDTV and
­Test Card M).
HDTV: The ¸DV-HDTV option provides an extensive transport stream
library containing high-resolution video
signals. To generate individual transport
streams, this option also includes these
video signals in the form of elementary
streams. The transport stream data is
already stored in the base unit. The function can be enabled by installing a software key. A separate data sheet is available for this option (PD 0757.6979).
Test Card M: The ¸DV-TCM option
supports the replay of a special collection of transport streams developed by
the Snell & Wilcox company and referred
to as Test Card M. The transport stream
data is already stored in the base unit.
The function can be enabled by installing
a software key. A separate data sheet is
available for this option (PD 0757.7369).
Recording: Transport streams can be
recorded at data rates up to 214 Mbit/s.
Exchanging transport streams with other
systems is no problem since the stored
files contain the transport stream packets in consecutive order and without
­additional headers.
As a special SPI feature, the recorder
and generator board also allows interface-specific data to be recorded simultaneously with transport stream data
(8 bits). It records the bits for signaling
the start of the packet (PSYNC) and for
the validity of the data (DVALID), thus
storing a total of 10 bits for 8 data bits.
Since recording is transparent, also nonDTV-compliant signals and even signals
of other applications can be recorded via
the interfaces.
Trigger

Sample signal: universal 4:3 Rohde & Schwarz codec test pattern
Digital Video Measurement System ¸DVM 400
The length of the pre- and post-trigger can be set on the ¸DVM
The recording of all signals can be controlled via the external trigger input of
the ¸DVM 400 base unit or the analyzer board. For this purpose, the ­applied
signal is continuously buffered. If a
trigger event occurs, the signal sections
both following the event (post-trigger)
and preceding the event (pretrigger) can
be stored. The length of the post- and
pretrigger can be set. It is thus possible
to determine where in the stored signal
the event is located. This function is particularly important for error analysis.
Replay of recorded signals
Replayed signals are applied to all
external transport stream interfaces
simultaneously (ASI/310M OUT 1, 2 and
SPI OUT). Signals 10 bits in width can be
replayed only via the SPI interface. For
optional analysis, the transport stream
signals are internally played to the analyzer board.
The signals are replayed in an ­endless
loop in such a way that the transition
from the end to the beginning of the
­recording always coincides with the
packet. Correct decoding of the video
and audio sequences in the replayed
transport stream is ensured only if the
original data rate of the recording is
used. For this reason, the data rate
of transport streams is automatically
­determined on the basis of the present
PCR values. Irrespective of this automatic recognition, the data rate can
be set by the user (up to ­214 Mbit/s).
Furthermore, the interfaces can be configured for playback.
Post-trigger
M 400 for triggered recording
t
The user can thus choose between the
“packet” and “continuous” operating
modes for the ASI ­interface. This feature
is especially crucial for router testing.
For the SPI interface, signaling can be
set via the “data valid” circuit. This flexibility allows versatile tests to be performed and offers maximum compatibility with other instruments.
Bit rates and memory
In the default state, transport streams
(GTS format) are generated from RAM.
They can be generated by inserting null
packets at data rates up to 214 Mbit/s.
The ¸DVM 400-B3 option additionally supports recording and replaying in
TRP format at data rates up to 90 Mbit/s
(TRP format).
A special feature is the packet-exact
cutting function for recorded transport
streams. It is thus possible to automatically replay specific sections of long
recordings in a loop or store them to a
hard disk for further analysis or simple
transfer to other instruments.
The ¸DVM 400-B4 option ­permits
­recording and replaying at up to
214 Mbit/s. Furthermore, this option
expands the available storage capacity for transport stream data from min.
60 Gbyte to min. 120 Gbyte.
Stream Combiner™
Stream Combiner™ enables easy expansion of the transport stream library that
is supplied. New transport streams can
be quickly generated from supplied or
recorded elementary streams. Used as
an offline multiplexer, Stream Combiner™
automatically integrates all program
information, service and system tables
(PSI/SI/PSIP) required in accordance with
MPEG-2 and the selected standard (ATSC
or DVB).
How to generate a transport stream
in a seamless endless loop
Transport streams can be seamlessly
generated in an endless loop (GTS
mode), provided the following two
­conditions are met:
In addition, Stream Combiner™ allows
the user to edit, add to or remove all
table contents – even in violation of
standards – in order to generate test signals for specialized tasks. The transport
stream files can be generated in GTS
or TRP format. A separate data sheet is
available for this option (PD 0757.3611).
◆ All time stamps (PCR, PTS and DTS
values and entries in the TDT, TOT
and STT tables) in the transport
stream must be updated in realtime
◆ The individual elementary streams
must be calculated or cut in such a
way that they end with a complete
GOP (video) or an entire frame
(audio) so that no errors occur in
the decoder; plus, they must be
calculated in such a way that the
average buffer fill state remains
constant during a loop period to
avoid any buffer underflow or overflow during continuous replay in an
endless loop
If these conditions are met, the transport stream appears to be continuously
generated in realtime directly from a
multiplexer and a number of encoders
connected to it, although the video,
­audio and data contents are repeated.
