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.
