Method of determining motion vectors and a reference picture index for a current block in a picture to be decoded

摘要

In one embodiment, the method includes obtaining first and second motion vectors of a block other than the current block. The other block neighbors the current block at one of a left, top and top right position. First and second motion vectors of the current block are determined using the first and second motion vectors of the other block such that the first motion vector of the current block has a same direction as the first motion vector of the other block and the second motion vector of the current block has a same direction as the second motion vector of the other block.
