ABSTRACT:
Video encoder and decoder, provided with a motion compensator for motion-compensated video coding or decoding in which a picture is coded or decoded in blocks in alternately horizontal and vertical steps. The motion compensator is provided with addressing means (160) and controlled multiplexers (111-119) for refreshing a search area memory (101-109) at each step, in conformity with the direction of the step.
