Real-time Monitoring

The MTS300 uses intuitive icons and colors to indicate the current status of MTS300 I/O ports and any MPEG transport stream under analysis. A simple, easy-to-use display indicates:

The current usage and status of the MTS300 I/O ports.You can install up to four I/O ports on an MTS300

The current status of monitored transport streams and the programs within monitored transport streams. Highly visible indicators let you quickly identify the transport stream or program with problems

The type of problem detected in a monitored transport stream. Intuitive icons show problems in transport stream protocol, timing errors, or problems in the video or audio elementary streams

Using this display,you can easily configure and control the product in real-time testing applications, to quickly identify and diagnose problems with designs or to characterize design or system performance.

Status and error logging

Deferred-time Analysis and Custom Transport Stream Creation

A collection of optional MTS300 software gives you powerful tools for analyzing MPEG-2 transport streams in detail and for creating your own custom streams to use in functional and stress testing.

Option DT – Deferred-time analysis and stream

creation: software tools for detailed syntactic and semantic analysis of the transport stream, including T-STD buffer simulation, and for creating custom streams, including error and jitter injection utilities

Option ES – MPEG video and audio elementary

stream analysis: Software tools for detailed analysis of MPEG video elementary streams, including GOP (Group of Picture) structure and I-frame decoding, and fo r detailed analysis of MPEG audio elementary streams, including extraction of audio content into .WAV files

Option AC3 – Dolby Digital AC-3 analysis:

Software for detailed analysis of Dolby Digital AC-3 audio content

Option TM – Transmission Multiplexing

Configuration Control (TMCC) Combiner: Software for adding TMCC information into transport streams

New Advanced Multiplexer and DVB/ATSC Table Editor – Multiplexer (Option MTS3FMX)

The software can re-multiplex:

MPEG-2 Video elementary streams MPEG-2 Audio elementary streams AC-3 Audio elementary streams MPEG-2 Video PES (packetized

elementary streams) MPEG-2 Audio PES AC-3 Audio PES PIDs from other transport streams Other data – the bit rate must be specified

The Solution

The multiplexer allows the user to collect together components from streams recorded off hard disk or CD/DVD-ROM, manipulate them in an unlimited manner and then rebuild a fully compliant output stream for whatever use is desired.Along the way, the system’s in-built syntax knowledge of tables and descriptors ensure compliance and high quality output of the final multiplex transport stream.

Decompose Existing Streams

MTS300’s off-line multiplexer accepts any recorded transport stream as an input source. The user can then decompose this transport stream into its component PES.The user can then save resulting PES and ES streams onto disk.

MTS300

Regroup Them with Stored Streams

These PES or elementary video and audio streams can be grouped together into logical groups – “Programs” of video, audio and other associated data (private data, e.g., teletext). The original timing relationships are preserved. These streams and/or other prerecorded PES or ES streams can then be reassembled together to build up a totally new transport stream as the user desires. Regrouping of elementary streams or programs can be achieved within an existing transport stream, by allowing the individual stream identifiers (PIDs) to be remapped as required.

Map, Check and Rebuild Your Own Multiplex

These streams can then be rebuilt into a larger multiplex stream and new system information tables can be customized and added. Powerful syntax auto-check warn the user of mis-mapped, reserved or duplicate PIDs, including the Program Paradigm, by checking and automatically updating PAT,PMT and derivable fields (in its “standard”mode) accordingly, to create a final legal and DVB or ATSC-compliant output stream. MTS300’s multiplexer allows the user to be able to construct a transport stream for any rate equal to or greater than the sum of the individual components to be multiplexed. Another facility offered is the ability for the multiplexer to insert correct PCR values on the PIDs defined by the user.This allows for PCRs to be on a separate PID or embedded on an existing PID.

Generate Compliant Timing and Output Bit Rates As Required

The multiplexer is able to insert the PCRs at the correct repetition rate and also allows the user to specify the PCR repetition rate, if desired.

Create, Add or Modify SI Flexibility

The multiplexer allows all of the standard MPEG/DVB/ATSC system information tables (SI) and descriptors to be edited.The user is permitted to generate illegal conditions that allow stress of decoder or transmission chain equipment to verify its robustness. It is also possible to generate private tables and descriptors.

Test Feature – Deliberately Create Illegal Streams

The software can be set to generate an optional warning when certain illegal conditions have been generated.This is visible clearly on the user interface. In a similar manner, the multiplexer allows all legal descriptors to be added to each table.The repetition rate for each table can be changed, overriding the default value.A conditional warning is generated if an illegal repetition rate is defined.

“Expert” and “Standard” Modes

Standard Mode will calculate related fields and table pointers (e.g., checksums) for the user without having to worry,but an Expert Mode is also provided to allow the user to set these to illegal conditions for test conditions as described above.

New Advanced Video and Audio Elementary Stream Analysis and Display – ES Analyzer (Option MTS3FIN)

This application brings to MTS300 not only the ability to actually view the moving picture from within a PES stream, but also to carry out a whole range of sophisticated new tests on the lower layers of an elementary stream within a transport multiplex.This gives added confidence when analyzing streams because encoder performance can be verified right down to slice and block layer together with motion vectors (see Figures 1 and 2).

Display and analysis of GOP, Picture, Slices and Macroblock layer

Picture quality analysis including Quantizer Scale distribution, motion vector graphs, macroblock and picture-size plots

The sequence header can be viewed along with the extensions.The picture rate, chroma format and the video type (NTSC, PAL,etc.) appear in the status bar when the sequence headers are displayed.The stream can be run through with the option of analysis of the stream at picture level or at the macroblock level.When analyzing the group of pictures (GOP), it is possible to randomly access any picture from within the group, view the picture type, spectrum and display picture size plots.

The user can zoom in on the picture to see details at the slice or macroblock levels or view the encoded picture. Picture player (see Figure 3) can be operated until degradation in quality is seen, the picture paused and the details reviewed down to the macroblock level. An easy mechanism is provided to switch between the picture display and the dat a analysis windows.

Macroblocks can be selected and detailed coding investigated.The picture analysis can be performed with special displays of quantizer scale distribution, slice size distribution, macroblock-size spectrum and motion vector plots.

Quantizer matrices can be downloaded for any picture, at most four matrices, namely intra-quantizer matrix, non-intra-quantizer matrix, chroma intra-quantizer and chroma non-intra-quantizer matrix.

The picture coding extension is always displayed, while the other picture extensions are displayed on tabbed folders; these are copyright extension, picture display extension (PDE), picture spatial scalable extension (PSSE) and picture temporal scalable extension (PTSE).The B and P frame motion vector displays allow you to select Macroblock Intra, pattern motion backward and forward together with macroblock quantization, quantizer scale DCT type and motion vector format.

Comprehensive error logging is provided during stream analysis and selectable error filters are available.There is also an automated “regression” test mode that can save data from selected fields to report files for viewing later.

The audio analysis capability includes navigation to any audio frame and viewing its details, header,frame data plots. Audio descriptors are interpreted and displayed in higher level streams and validated against the stream.
