Abstract

The invention discloses an apparatus for decoding a video sequence, compressed according to a known data modelling method suitable for transmission or storage, into decompressed frames, suitable for viewing, said encoded data model comprising a plurality of spatial intensity change 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, 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 change pattern and corresponding scores into an intermediate image; (d) means for aggregating (340, 352; 446, 474) the contributions from each address change pattern and corresponding scores into a motion field; (e) means for displacing (360) the contents of the intermediate image according to the motion field, producing a final frame (370), 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. The invention further discloses a corresponding image decoding method.
