ABSTRACT:
A band compression signal processor including a band compression circuit for intra-frame-coding and inter-frame-coding an input video signal which forms a picture areas, inter-frame-coding the input video signal which is intra-frame-coded, and repeating the above signal processing adaptively according to a motion evaluation on the input video signal, and a refresh coding circuit for periodically intra-frame-coding signals corresponding to b areas of the a areas for each frame at a period of f frames. A macro-block is formed by adding overhead data indicating the contents of variable length codes of a refresh block and a non-refresh block to the refresh block which has undergone the refresh coding and the non-refresh block which has not undergone the refresh coding.
