Claim 2:
3. A non-transitory computer-readable medium for recording a bitstream, the bitstream comprising:
a disparity distance index; and
a disparity direction index,
wherein the disparity distance index and the disparity direction index represents a first motion vector difference for a first list,
wherein the first motion vector difference for the first list is obtained by using a first motion vector of a current block for the first list and a first base motion vector for the first list,
wherein if it is determined that the current block is to be bi-predicted, a second motion vector difference for a second list is derived based on the first motion vector difference, a picture order count (POC) of a current picture, a POC of a first reference picture in the first list, and a POC of a second reference picture in the second list, and
wherein the disparity distance index indicates a value of a power of 2.
