ABSTRACT:
In a video signal coder/decoder arrangement or codec for an image transmission system motion of picture elements between frames is encoded with reference to any one of eight preceding frames, so that picture information which repeats within eight frames does not need to be encoded again, and recovery after errors in transmission can commence with reference to the last-received uncorrupted frame of the eight.
