MPEG program stream demultiplexer software library module


  • The MPEG-1 program stream demultiplexer library accepts MPEG2 program streams as described in ISO/IEC 13818-1, Recommendation H.222.0 and MPEG1 system streams as described in ISO/IEC 11172-1. If the stream is a program or a system stream, the DemuxMpegPS component looks for a pack start code and extracts the system clock reference from the pack header. The demultiplexer will report the system reference clock, using the progress function. DemuxMpegPS extracts the stream IDs for the following data types: Mpeg audio stream, private AC3 audio streams, private PCM audio streams, private Subpic streams, and Mpeg video streams.


  • MPEG-1 program stream demultiplexing
  • compatible with TriMedia Software Development Environment
  • supported by pSOS+ real-time operating system
  • can be demonstrated on TM-1300 IREF board


  • MPEG-1 allows real time video to be compressed for transmission.
