CMA 1820 Compressed Media Analyzer Software


Overview

The CMA 1820 is an ideal solution for compressed media in-depth analysis and decoding compliance.  It has support for H.264, MPEG-2, and VC-1 video along with AC-3, AAC, and MPEG audio.  There are also enhanced analysis options for MPEG-2 and H.264 closed captions and detailed PTS/DTS alignment.

The CMA 1820 decodes pictures from the video elementary streams (ES) and displays the information using picture overlays and data boxes.  Key information on coding parameters is given including slice and macroblock level data.   The syntax view provides values and descriptions of all the syntax elements down to the syntax header level.   The analyzer also includes a Dynamic Buffer Analysis for H.264 that tests the compliance of the bitstream to the Hypothetical Reference Decoder Model.

Features

H.264 Video Capabilities:

  • Video Decoding
  • Macroblock (MB) details with partition grid, overlays for MB types, MB size in bits, MB quantization parameters (QP) and motion vectors; plus detailed characteristics with reverence picture list content and Coded Block Pattern (CBP)
  • Extraction of H.264 raw byte within a desired video picture range
  • Detailed NAL syntax and conformance testing
  • Dynamic buffer analysis; HRD model for CPB and DPB buffers

MPEG-2 Video Capabilities

  • Video Decoding
  • Macroblock (MB) details with partition grid, overlays for MB types, MB size in bits, MB quantization parameters (QP) and motion vectors; plus detailed characteristics with prediction mode and coded block patterns.
  • Extraction of MPEG-2 video raw byte files within desired video picture range
  • Detailed syntax view with compliance checking
