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

摘要

In one embodiment, the apparatus includes a decoder. The decoder is configured to obtain first and second motion vectors and a reference picture index of a block other than the current block. The decoder is configured to obtain a direction of the first and second motion vectors. The decoder is configured to determine first and second prediction motion vectors of the current block using the first and second motion vectors of the other block such that the first prediction motion vector of the current block has the obtained direction of the first motion vector of the other block and the second prediction motion vector of the current block has the obtained direction of the second motion vector of the other block.
