Abstract

In a video processing system where motion vectors are estimated for a subset of the blocks of data forming a video frame, and motion vectors are interpolated for the remainder of the blocks of the frame, a method includes determining, for at least at least one block of the current frame for which a motion vector is not estimated ( 204 ), whether a block to the left or right has an estimated zero motion vector ( 206 ), determining whether the at least one block had an estimated zero motion vector in a previous frame ( 206 ), and if both determinations are affirmative ( 208 ), providing a predetermined motion vector for the at least one block. The predetermined motion vector may be a zero motion vector ( 208 ).
