ABSTRACT:
In, for example, a motion compensated video standards converter wherein blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the next succeeding field or frame of the video signal for deriving motion vectors representing the motion of the content of respective blocks between the first field or frame and the next field or frame, the blocks adjacent to a border region of the field or frame are assigned motion vectors selected from the motion vectors which have been derived for those of the blocks which are adjacent to the block under consideration and are not in the border region.
