Tokens-based adaptive video processing arrangement
First Claim
1. For use with a video decompression system having a plurality of processing stages:
- a universal adaptation unit in the form of an interactive interfacing token, for control and/or data functions among said processing stages, wherein said unit is dynamically adaptive and causes said processing stages to reconfigure;
wherein said system operates on a data stream having a plurality of video formats carried therein, and said unit comprises a plurality of units that contain data encoded in different ones of said video formats, and said units are transmitted sequentially through said processing stages and are altered by interfacing with said stages, altered units being transmitted to a subsequent processing stage;
whereby said processing stages are afforded enhanced flexibility in configuration and processing.

Abstract
A multi-standard video decompression apparatus has a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine. Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and data in token format. A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens pertinent to that stage and for passing unrecognized control tokens along the pipeline. Reconfiguration processing circuits are positioned in selected stages and are responsive to a recognized control token for reconfiguring such stage to handle an identified DATA Token. A wide variety of unique supporting subsystem circuitry and processing techniques are disclosed for implementing the system.

36. In a video decompression system having an input, an output and a plurality of processing stages between the input and the output, the improvement comprising:
-
said system operating on a data stream comprising a plurality of video formats, an interactive metamorphic interfacing token, transmitted sequentially through said processing stages, defining a universal adaptation unit, for control and/or data functions among said processing stages, wherein said unit is dynamically adaptive and causes said processing stages to reconfigure, said tokens having video format information encoded therein indicative of a current video format; said processing stages comprising an inverse modeler, a Huffman decoder, and an inverse discrete cosine transform circuit; wherein each of said inverse modeler, said Huffman decoder, and said inverse discrete cosine transform circuit are reconfigured in response to said encoded video information. - View Dependent Claims (37)
