CPC H04N 19/44 (2014.11) [H04N 19/105 (2014.11); H04N 19/132 (2014.11); H04N 19/159 (2014.11); H04N 19/176 (2014.11); H04N 19/46 (2014.11)] | 2 Claims |
1. A video decoding method, comprising:
determining whether a right block is available for a current block according to a flag indicating a coding order of blocks including the current block and the right block;
when the right block is available for the current block, obtaining control point motion vectors as an affine merge candidate, using a motion vector of a first block in the right block, wherein the first block is adjacent to a lower right corner of the current block;
when the right block is unavailable for the current block, obtaining the control point motion vectors as the affine merge candidate, using a motion vector of a second block included in a collocated picture, wherein the second block is a collocated block located at a point diagonally adjacent to the lower right corner of the current block; and
obtaining predicted samples of the current block, using a motion vector included in an affine merge candidate list including the affine merge candidate.
