Claim 1:
2. An apparatus for encoding motion information, the apparatus comprising:
a motion vector encoder configured to:
obtain a first motion vector difference for a first list by using a first motion vector of a current block for the first list and a first base motion vector for the first list, and
if it is determined that the current block is to be bi-predicted, derive a second motion vector difference for a second list, 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

a generator configured to generate a bitstream including a disparity distance index and a disparity direction index, the disparity distance index and the disparity direction index representing the first motion vector difference,
wherein the disparity distance index indicates a value of a power of 2.
