Abstract

A video syntax parser is provided for a video decompression processor. A compressed bitstream is examined until a start code is located. The start code is decoded to enable a particular parser state corresponding thereto to be initiated. The parser state is communicated to a plurality of subsystems of the video decompression processor. Each subsystem monitors the parser state to determine which parsed data following the start code, if any, is intended for that subsystem. The subsystem then retrieves the parsed data it requires via a data bus which receives the parsed data from the parser.
