Intended Applications
  • The addition of the MTS400 MPEG analysis toolset to the MTX100B platform provides a complete solution for stream creation, editing, generation, and analysis on a highly portable platform. Ideally suited for in-field installation, commissioning, and debug of complex MPEG transmission systems, the analysis options offered with the MTX100B provide both real-time and offline Transport Stream analysis capability with ASI, SMPTE310M, and IP interface options.

Introduction/Overview

Tektronix’ industry leadership offers the broadest (across multiple standards and video layers) and deepest (in depth of generation and analysis) solution for compressed video test. The MTS400 Series MPEG tools can be applied anywhere at any level, to diagnose and solve the most subtle, complex, and intermittent DTV problems in the minimum time.

The MTS400 Series MPEG tools provide a comprehensive suite of analysis tools including Transport Stream (TS) compliance, buffer, PES, compressed video and audio elementary stream analyzers, together with TS editor, multiplexer, and data broadcast applications for stream creation, analysis, and error injection.

Standards compliance is ensured though 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, and MPEG. To keep analysis up to date, 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.

Player and Recorder

The MTX100B MPEG-2 Recorder and Player offers a flexible, affordable solution for design evaluation and conformance testing of digital video products using MPEG-2 technology. The MTX100B records and plays out MPEG-2 Transport Streams compliant with ATSC, DVB, and ISDB standards at the high data rates needed to verify and troubleshoot designs for high-performance video products and systems. The large internal storage, USB 2.0, and Ethernet download capability help you build and maintain a large library of test streams.

The MTX100B offers continuous, error-free Transport Stream looping for long duration playout, and PCR Jitter insertion for stressing designs. Users can continuously loop all sample streams, including updating of all time stamps, continuity counters, time tables (TDT, TOT, and STT), Normal Play-time Reference, and ISDB-T Reed Solomon FEC, without fear of buffer under- or overflow.

An Ethernet network remote control functionality enables control of functions such as Play, Record, Clock Rate, and Jitter Insertion using the SCPI (Standard Control for Programmable Instruments) command set.

The MTX100B can play any Transport Stream files, including custom Transport Streams created with offline multiplexers in the Tektronix MPEG Analysis Tools. In addition, the MTX100B can play data files in other formats, including elementary streams and files in DSS format.

Summary of Analyzer Options

Transport Stream Compliance Analyzer (TSCA, TSCX)

Thumbnail

The MPEG Transport Stream Compliance Analyzer (TSCA) is a new class of software-based analysis tool, the world’s first Compressed Digital Video Debugger/Analyzer that introduces the CaptureVu™ feature, a new-to-market capability that captures and analyzes system events to debug the intermittent and complex problems that traditional software-based analyzers miss.

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.

The TSCX is a real-time version of the TSCA analyzer operating on all of the connected stream interfaces as well as IP through the Ethernet port. The real-time analysis also includes Cross Layer time-correlated IP and TS measurements, alarms, and error logging together with stream recording.

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.

Multiplexer and SI Table Editor

Multiplexer and SI Table Editor

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 (system information) or other tables, or are multiplexed to the incorrect Transport Stream rate for the application.

Use the Multiplexer/Remultiplexer/Demultiplexer application to create multiprogram Transport Streams with custom SI/PSI/PSIP information for DVB, ATSC, ISDB, and MPEG compliant Transport Streams. A new ISDB-T Single Segment mode is added in version 3.1.

H.264 Elementary Streams may also be multiplexed into a Transport Stream. H.264 streams, both with and without SEI timing messages, are supported. The PTS and DTS generated for non-SEI streams are based upon the POC (Picture Order Count) information. PTS/DTS generation may be suppressed for SEI streams. Bit rate and frame rate auto-detection features aid the import process. These may be overridden for non-SEI streams.

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.

Packetized Elementary Stream (PES) Analyzer

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.

Buffer Analyzer

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 amongst 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 contain buffer parameters within the ES itself. 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.

Carousel Analyzer

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.

Carousel Generator

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, DVB, DTT (MHEG-5), or MHP standards.
