The MTS4EAV7 HEVC / AVC Video and Compressed Audio Analyzer is a powerful PC-based software package for deferred time analysis of encoded video and audio elementary streams. Supported video standards include HEVC (H.265), AVC / H.264, VC-1, MPEG-2, MPEG-4 part 2, and H.263. Supported audio standards include MPEG-2 audio, AAC, and AC-3. Also included are closed caption analysis capabilities. The MTS4EAV7 analyzer is available for standalone or networked PCs, and for Tektronix MTS4000 MPEG Test Systems.

Key features
  • Video, audio and caption decode and analysis
  • Verification of the stream’s compliance with the encoding standard
  • Extraction of elementary streams from containers
  • Comprehensive stream navigation and tracking to follow all aspects of the decoding process
  • Multiple displays and overlays of Coding Unit (CU), Prediction Unit (PU), Transform Unit (TU), Macroblocks (MB)
  • Easy selection of specified CU/MB and navigation using Zoom in and out for analysis
  • Synchronized video, audio, and data views for instant cross reference
  • Wide range of frame and Coding Tree Unit (CTU), Coding Unit (CU), Prediction Unit (PU), Transform Unit (TU), macroblock statistics, syntax traces – bitstream, interpret, alerts, frame, macroblock, transform, pixel level, fidelity traces
  • Buffer analysis with graphical plots – spatial bits/MB, MV histogram, quantization, DCT frequency, MB coded frequency, intracoding frequency
  • Video differencing and fidelity analysis
  • Bitstream editor for making changes, reanalyzing the stream, then saving
  • Exports data for detailed graphical analysis (requires Microsoft Excel®)
  • Comprehensive batch mode for automated regression testing with log reports
  • YUV decoded video output for baseband video analysis
  • Audio compression analysis
  • AV delay measurement
  • Built-in help and tutorials
  • Quicker and partial analysis by extracting to smaller files
  • Closed Caption syntax and compliance analysis with ability to render captions over video, save captions to standard file format (SRT, SCC MCC), and debug capabilities, with support for Korean characters

Intended users and applications
  • Equipment manufacturers
    • Video codec software and hardware developers
    • Semiconductor device designers and manufacturers
    • Mobile video infrastructure and mobile device developers
  • Video content transmission and distribution
    • CODEC and equipment evaluation and comparison in cable, satellite, terrestrial, and IP applications
    • Network operators and network equipment providers
    • Application and service providers and streaming media applications
    • Broadcasters for checking AV delay

Elementary stream analysis

Video compression standards are complex and involve many elements which are vitally important to the efficiency and interoperability of compressed video in different applications. The MTS4EAV7 analyzer provides verification of the compliance of the stream against the compression standard, detailed analysis and statistics of the video and audio streams, tools for editing and debugging the stream, fidelity comparison against the original uncompressed stream, and checking for any video and audio delay.

Analysis of intermediate HEVC/H.265 and H.264/AVC transform values is included, as well as ARIB TR-B14 compliance verification. It enables equipment and systems developers to test and bring new designs rapidly to market, and video users to test compliance, interoperability, and performance of compression products.
