ABSTRACT:
A system and method for more efficiently determining motion vectors of uncovering areas adjacent the edge of frames when the frame image is moving in the direction of the frame boundary. Backwards motion estimation is used to determine a block of video data which is, in one implementation, the block of video data adjacent the frame edge having a reliable motion vector known from the first frame. Once the block is identified, the blocks of video data in the uncovering area between the identified block and the frame boundary can then be assigned the motion vector data of the identified block.
