Abstract

A video and graphics system includes a data transport processor for receiving compressed data streams, a video transport processor for extracting video data, and an audio decode processor for extracting audio data. The data transport processor provides PCRs to the video transport processor and the audio decode processor. The video transport-processor stores the video data in external memory and generates a start code table to index the video data stored the external memory. In the start code table SLICEs of the video data are aligned to a suitable boundary. The compressed data streams may include MPEG Transport streams, and the video data may include SDTV or HDTV data. The video and graphics system may be implemented on an integrated circuit chip.
