Abstract

A coding system for digital signals corresponding to televi-sion pictures of a determined definition, incorporating an image rebuilding stage comprising a first image rebuilding channel ac-cording to said determined definition and a second image rebuild.
ing channel according to a reduced definition, which is parallel on said first channel, and corresponding decoding system also incor-porating an image rebuilding stage giving said reduced definition from decoded signals, associated with a decoding stage, a motion compensating stage using additional motion information, and a prediction stage using the output signals of said image rebuilding stage. This system is for use on television receivers.
