A VIDEO DECODER AND A VIDEO ENCODER USING MOTION-COMPENSATED PREDICTION

摘要

A video decoder using motion-compensated prediction has a predictor configured to predict a first subset of parameters of a plurality of motion parameters, defining the motion-compensated prediction of a predetermined region of a picture of a video, to obtain a prediction for the first subset. The video decoder further has a reconstructor configured to reconstruct the first subset of parameters from the prediction of the first subset and residual information for the first subset contained in a data stream, to obtain a reconstruction of the first subset. The predictor is further configured to predict a second subset of parameters of the plurality of motion parameters, being disjoint from the first subset, using the reconstruction of the first subset.
