Apparatus and method for decoding video images
First Claim
1. An apparatus for decoding a video sequence, compressed according to a data model suitable for transmission, storage or analysis, into decompressed frames suitable for viewing, said data model comprising a plurality of spatial intensity change patterns, called intensity loads, a plurality of spatial pixel address change patterns, called address loads, and a plurality of values, called scores, specifying for each frame how much of each load should be present,the apparatus comprising:
- (a) means for receiving (320;
406,
408) and storing (326;
414,
416) the plurality of intensity loads and the plurality of address loads,(b) means for receiving and storing (328;
442) the plurality of scores,(c) means for aggregating (340, 354;
446,
476) the contributions from each intensity load and corresponding scores into an intermediate image,(d) means for aggregating (340, 352;
446,
474) the contributions from each address load and corresponding scores into a motion field,(e) means for displacing (360;
492) the contents of the intermediate image according to the motion field, producing a final frame (370;
497,
498),wherein means (a) to (e) are connected in such a way that a pipeline consisting of parallel synchronous data paths is formed, through which pipeline the intermediate image and motion field are continuously transmitted.

Abstract
The invention discloses an apparatus for decoding a video sequence, compressed according to a known data modeling method suitable for transmission or storage, into decompressed frames, suitable for viewing, the data model comprising a plurality of spatial intensity changes patterns, called intensity loads, a plurality of spatial address change patterns, called address loads, and a plurality of values, called scores, specifying for each frame how much of each load should be present. Each of the loads includes respective hardware components for storing and processing it. The respective components are connected in a pipeline consisting of parallel synchronous data paths, through which pipeline the intermediate image and motion field are continuously transmitted.
