A system of coding moving image signals produces a predictive error signal by a predictive coding based on inter-frame correlation and quantizing the predictive error signal for each block of a picture frame constituted by N lines of M pixels. The system includes a block coding/non-coding decision unit...http://www.google.fr/patents/US4837618?utm_source=gb-gplus-shareBrevet US4837618 - Moving image signal coding system
