Abstract:
In one embodiment, the apparatus includes a decoder. The decoder is configured to obtain 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. The decoder is configured to obtain a direction of the first and second motion vectors of the neighboring block. 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 neighboring block such that the first prediction motion vector of the current block has the obtained direction of the first motion vector of the neighboring block and the second prediction motion vector of the current block has the obtained direction of the second motion vector of the neighboring block.
