Claim 13:
14. The apparatus according to claim 13, wherein each candidate pair (CMV0, CMV1) is associated with the first extension block and the second extension block, and wherein for obtaining the target motion vector offset with the smallest cost among the one or more motion vector offsets based on the matching cost comparison involving the one or more first reference block and the initial prediction block, the video coder is further configured to:
determine positions for the top-left sample of the first extension block and the second extension block corresponding to CMV0 and CMV1 respectively; and
compute a matching cost value between predicted samples within the first extension block and the second extension block, wherein a size of the first extension block is (sbWidth+2*Ox)×(sbHeight+2*Oy), and
wherein Ox is an amount of one-sided extension in the horizontal direction, and Oy is an amount of one-sided extension in the vertical direction.
