This text introduces some main technology and standard about the information source encoding of digital TV including the digital broadcasting studio standard ITU-601, the basic principle and method of the compress encoding, standard of the picture compression encoding, H261, JPEG and MPEG, and forming bit stream MPEG-2 as information source encoding standard export of digital TV.

The management of the bitstream and the parsing of video data are the basis of the video decoder.

Based on the TMS320VC5402 DSP McBSP characteristics and the PCM Encoding and Decoding chip TP3067 Characteristics, The paper provides McBSP of DSP acquires PCM data, The DSP and TP3067 simultaneously in standard E1 achieve time-division exchange between different Bitstream channel.

Theory and Realization on Stream Conversion from MPEG-1/2 to MPEG-4;

According to the requirement of the DTV development, the scheme is designed for a novel MPEG2 stream construction system integrating a video-audio source encoder with the multiplexer.

A digital video watermarking algorithm based on MPEG-4 streams;
