Abstract:
In a transport demultiplexor, a method of decoding a time-division multiplexed bitstream containing packets of audio, video, and system data, where each packet has a packet header, and packet data bytes, said method comprising demultiplexing the bitstream into separate audio and video data bitstreams for decompression while maintaining synchronization, attaching an information word to at least some audio, video and system data packets, loading the demultiplexed system data and the demultiplexed audio and video data packets and their attached information words into a single logical buffer, wherein the system data, the audio data and the video data packets are stored intermixed in the single logical buffer of the transport demultiplexor, unloading the system data and the audio and video data packets from the single logical buffer using the attached information words, and decoding the audio and video data bitstreams in accordance with the system data using audio and video decoders.
