Transport Stream Compliance
Analyzer (TSCA)
The TSCA offers significant
enhancements over traditional software-based deferred-time (stored
streams) MPEG analyzers. The combination of an innovative high-speed
analysis engine and built-in intelligence, allows ultrafast pinpointing
and debugging of intermittent faults in MPEG Transport Streams used
in next-generation DTV and IPTV systems and services.
The TSCA
also provides real-time analysis of Transport Streams received through
the MTS400’s stream interfaces, including an optional IP Video interface.
The real-time analysis includes cross-layer time-correlated IP and
TS measurements, alarms, and error logging together with stream recording.
The TSCA includes the CaptureVu™ technology and PCR measurement
and graphing capabilities. CaptureVu™ technology captures and analyzes
system events in real time and deferred time to debug the intermittent
and complex problems that traditional analyzers miss.
Standards
compliance is ensured through built-in customizable scripting supporting
the broadest ranges of ratified and evolving DTV standards, including
ATSC, DVB-C, DVB-H, DVB-S, DVB-T, ISDB-S, ISDB-T, ISDB-TB (Brazil),
and MPEG. To maintain compatibility with the latest standards, flexibility
is the key. New standards and proprietary tables can easily be catered
for by loading Tektronix-supplied updates, or creating your own custom
scripts.
Users can configure the TSCA software to display stream
information in user-selected fonts. This feature enables you to view
stream information in your local language or to use custom fonts.
Note: Only real-time TSCA is included as standard, deferred-time
operation is an option.
Creating, Editing, and Resizing Transport
Streams
Two direct stream manipulation packages are supplied
as standard with the MTS400. TS Cutter allows resizing of Transport
Streams. TS Editor allows direct editing of Transport Streams using
a hexadecimal view as well as a header interpretation guide.
Summary of MTS400P Optional Tools
Player
The Player tool provides a Transport Stream stimulus for a device
under test through the ASI, SMPTE310, LVDS (DVB Parallel), or IP stream
interfaces. Continuous playout of looped streams is possible at up
to maximum ASI rate of 214 Mb/s with automatic updating of time stamps.
Playout rate can be automatically determined from file PCRs or manually
set. Simultaneous playout and recording (duplex operation) for end-to-end
system test is supported with the ASI/SMPTE310M and LVDS interfaces.
Playout through the IP interface provides stimulus with parametric
capabilities and multisession replication to characterize behavior
of a network or device under test. This capability enables equipment
manufacturers developing hardware or software solutions for video
distribution over IP and IPTV to ensure quality and performance of
products, resulting in reduced development costs and accelerated rollout
of next-generation IP broadcast services.
Multiplexer
When testing network elements or set-top boxes, a Transport Stream
of the representative type needed is often not available. Even if
there is a similar one, vital components within it may be missing
or suffer from a lack of SI (Service Information) or other tables,
or are multiplexed to the incorrect Transport Stream rate for the
application.
Use the Multiplexer/Remultiplexer/Demultiplexer
application to create and modify multiprogram Transport Streams with
custom SI/PSI/PSIP information for DVB, ATSC, ISDB*3, and
MPEG compliant Transport Streams.
Video and audio Elementary
Streams may also be multiplexed into a Transport Stream. H.264 streams,
both with and without SEI timing messages, are supported. Bit rate
and frame rate auto-detection features aid the import process.
This enables the user to create their own test streams that they
can use to validate and debug their designs more quickly, and also
to create errored streams to perform parametric stress testing and
ensure robustness and quality of their MPEG-2 or H.264 implementation.
The Make Seamless wizard is provided with the Multiplexer.
When looping a Transport Stream to simulate continuous playout, errors
can be generated at the loop point caused by discontinuities in timing
information. The Make Seamless wizard provides the opportunity of
creating a seamless version of a Transport Stream file by adjusting
SI and ES components within the stream.

includes ISDB-TB (Brazil) and a Single Segment mode.
Buffer
Analyzer
When developing professional and consumer equipment,
particularly encoders and set-top boxes, the characteristics of the
test streams being either generated or used as stimulus need to be
ascertained. Of critical importance among these characteristics is
adherence to the buffer model. That is, when the stream is processed
by a receiver, will any of the internal buffers be caused to either
under- or overflow. Consequences of these conditions will be freeze
frames and receiver resets.
There are two types of buffer model;
the one to use by the receiver is signaled within the Elementary Stream
itself. The T-STD method is based upon the DTS values within the PES
header and can be used for any contained CODEC type. Additionally,
certain video CODECs such as MPEG-2 and H.264/AVC may signal buffer
parameters within the ES. The Buffer Analyzer verifies conformance
of a stream to the T-STD model. Verification of the H.264/AVC HRD
method is covered by the MTS4EA product.
Packetized Elementary
Stream (PES) Analyzer
When developing professional
and consumer equipment, particularly encoders and set-top boxes, the
characteristics of the test streams being either generated or used
as stimulus need to be ascertained. The header associated with each
PES packet is of particular interest, as it contains the decode and
presentation time stamps (DTS and PTS) for the contained Elementary
Stream. Errors in these time stamps may cause resets or picture freeze
problems at the receiver in extreme cases. They are more typically
the cause of lip sync problems where the time stamps of associated
video and audio streams are not synchronized. The PES Analyzer is
designed to help address these problems as well as verify conformance
of the PES header contents to the MPEG, DVB, and ATSC standards.
Elementary Stream (ES) Analyzer
The ES Analyzer is intended
for CODEC design, optimization, and conformance purposes. It provides
the ability to view the moving picture from within a PES stream and
carry out a whole range of sophisticated tests on the lower layers
of an elementary stream within a Transport Stream. In addition, it
both analyzes and displays a range of extended media formats, including
ATSC Closed Captions, DVB Subtitles, and Teletext associated with
video Elementary Streams.
For analysis of MPEG-4, AVC/H.264,
and VC-1 as well as MPEG-2 Elementary Streams, please refer to the MTS4EA data sheet (2AW-18069).
Carousel Analyzer
When developing either data or object carousels for interactive
applications, designers not only need to verify the content of carousels,
but also whether they are compliant with the relevant standards, and
to optimize the settings between transmission bandwidth and responsiveness
of the user experience. These settings are mainly concerned with the
repetition rates of the various carousel groups. The Carousel Analyzer
is designed to address all of these needs for a Transport Stream file
containing carousel components. It analyzes carousels compliant with
MPEG-2 DSM-CC, DVB (including MHP), DTT (MHEG-5), or ARIB standards.
Carousel Generator
The Carousel Generator product
is used for creating object carousel contents within an output Transport
Stream. This is particularly useful in test situations where the effects
of varying parameters, such as individual repetition intervals, may
be quickly ascertained. The generator will create object carousels
conforming to the MPEG-2 DSM-CC, DVB, DTT (MHEG-5), or MHP standards.
