ABSTRACT:
A video signal is coded by intraframe coding. The coded video signal is then decoded by intraframe/field decoding. A decoded local video signal is generated, which corresponds to a specific region in one frame of a video signal coded one frame prior to the video signal. A first motion signal is generated, which indicates motion of pictures in both the decoded video signal and the decoded local video signal. The motion signal is then subtracted from the video signal to generate a predictive error signal which is then coded by intraframe coding. The coded video signal and the coded predictive error signal are decoded by intraframe/field-decoding. A second motion signal is generated, which indicates motion of pictures in both the decoded video signal and a video signal decoded one frame prior to a video signal to be reproduced. The decoded predictive error signal and the second motion signal are added to each other to reproduce the video signal.
