Abstract
A transport demultiplexor for demultiplexing an MPEG-2 compliant transport stream into a system data stream, a video data stream, and an audio data stream. The demultiplexor has frontend logic, a packet buffer, and data, video, and audio unloaders. The front end logic receives transport stream input packets, and delivers the transport stream packets to the packet buffer. The packet buffer, in turn, delivers system data to the system data unloader, video data to the video unloader, and audio data to the audio unloader.
