More specifically, this embodiment relates to the decoding of any one or the well known standards known as JPEG, MPEG and H.251. The illustrative embodiment chosen for description hereinafter relates to the decoding of a plurality of encoded picture standards. The present invention is directed to improvements in methods and apparatus for decompression which operates to decompress and/or decode a plurality of differently encoded input signals. This application claims priority from EPO Application No. 2, 1995, which is a continuation application of Ser. This is a continuation-in-part application of U.S. Methods relating to the decoder and decompression system include processing steps relating thereto 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. 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. The data words are thereby unlimited in number. Each data word has an extension bit which indicates a presence of additional words therein. A respective one of the tokens includes a plurality of data words. The start code detector responding to the single serial bit stream generates control tokens and data tokens. When in a search mode, the start code detector searches for a specific start code corresponding to one of multiple compression standards. The pipeline system employs a plurality of interconnected stages to decode and decompress the single bit stream, including a start code detector. 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.
