ABSTRACT:
An adaptive predictive coding system for television signals, in which noting the movement of a picture, adopts the inter-frame prediction value in a case of the picture being decided to be a still picture and, in other cases, compares the inter-frame, into-field and intra-field prediction values with each other in terms of magnitude taking into account the quantity of movement of the picture and adopts the prediction value which would not make the coding efficiency the worst, spo that a stable and high coding efficiency can be achieved.
