Abstract
A motion estimator for high definition television transmission comprises a device which operates after motions have been estimated for an image (51), when the motions in a following image (53) are to be estimated. This device associates with a part (R) examined in an image (53) a group (5) of a plurality of parts of the preceding image (51) which group contains the part occupying, in the image, the same position as the examined part and likewise the adjacent parts, and investigates whether one of the nine motions determined for the nine parts of the said group (5) can be applied to the part R. If this is the case, the operation of the estimator is terminated for the part (R) examined and, moreover, the transmission of the motion for this part is then effected not by transmitting the value of the motion, but by designating that one of the parts of the group (5), the motion of which is appropriate.
