Abstract
A method of decoding a multiplexed, system layer bitstream. The bitstream is made up of packets of audio, video, and system data. Each packet has a packet header, and data packets. The first step in the process is demultiplexing the bitstream into separate audio and video bitstreams for decompression while maintaining synchronization of the video and audio. The system data and the audio and video packets are next loaded into buffers, from which they are unloaded for subsequent decoding. The decoding is in accordance with the system data entries. The method is characterized by storing the system data and the audio and video packets in a single buffer.
