PROBLEM TO BE SOLVED: To provide an MPEG video extension method and a device using plural stages interconnected with a 2-wire interface arranged as a pipeline processing machine. SOLUTION: A control token and a data token are delivered to a single 2-wire interface carrying both the control of a token form and data. A token decoding circuit is arranged in a certain stage, certain tokens are recognized as the control token relating to the stage and the unrecognized control token passes through a pipeline. A rearrangement processing circuit is arranged inside a selected stage, responds to the recognized control token and reconstitutes the stage so as to handle an identified data token. The circuits and processing techniques of various original supporting sub-systems for operating a system including memory address specification, data conversion using a common processing block, time synchronization, asynchronous buffering, the storage of video information and a parallel Huffman decoder, etc., are presented. |
