查询词典 multiplexing

Audio and video steams accord with MPEG-2 standard can form PES after packeted, and then PES steam can form tranport stream after multiplexer. The transmitter conduct a number of transport stream multiplexing ,then send out the signal via satellite,cable or terrestrial transmitting station.The end user receiver picks up the DTV signal,demultiplexes it and finally the MPEG-2 decoder presents the decoded audio and video stream to the user.
