ABSTRACT:
Method and apparatus for encoding a video signal wherein the prediction errors for previously encoded pels are evaluated using motion compensation and frame difference predictions. Each present pel intensity value is then predicted using the technique which produced the smaller prediction error sum. Prediction errors for the present pel are encoded, together with address information, if the error exceeds a threshold value. The motion compensated prediction utilizes a displacement estimate which is recursively updated. A decoder is also described.
