A pipeline video decoder and decompression system handles a plurality of separately encoded bit streams arranged as a single serial bit stream of digital bits and having separately encoded pairs of control codes and corresponding data carried in the serial bit stream. The pipeline system employs a plurality of interconnected stages to decode and decompress the single bit stream, including a start code detector. When in a search mode, the start code detector searches for a specific start code corresponding to one of multiple compression standards. The start code detector responding to the single serial bit stream generates control tokens and data tokens. A respective one of the tokens includes a plurality of data words. Each data word has an extension bit which indicates a presence of additional words therein. The data words are thereby unlimited in number. A token decode circuit positioned in certain of the stages recognizes certain of the tokens as control tokens pertinent to that stage and passes unrecognized control tokens to a succeeding stage. A reconfigurable decode and parser processing means positioned in certain of the stages is responsive to a recognized control token and reconfigures a particular stage to handle an identified data token. Methods relating to the decoder and decompression system include processing steps relating thereto.

[ What is claimed is:] [1.]1. In a pipelined video decoder and decompression system for handling a plurality of separately encoded bit streams arranged as a single serial bit stream of digital bits and having separately encoded pairs of control codes and corresponding data carried in the serial bit stream and employing a plurality of stages interconnected by a two-wire interface, the improvement comprising:a start code detector responsive to the single serial bit stream for generating control tokens and data tokens for application to the two-wire interface, wherein a said token comprises a plurality of data words, each data word including an extension bit which indicates a presence of additional words therein, wherein said star code detector detects overlapping start codes in said bit stream and the first start code is ignored and the second start code is used to create start code tokens;a token decode circuit positioned in certain of said stages for recognizing certain of said tokens as control tokens pertinent to that stage and for passing unrecognized control tokens to a succeeding stage; anda reconfigurable decode and parser processing means responsive to a recognized control token for reconfiguring a particular stage to handle an identified data token.
