Abstract: A video decoding apparatus generates, by using the shape of the affine model and the control point motion vectors, motion vectors of subblocks partitioned from the current block. The apparatus generates a reference block of the current block by deriving sub-reference blocks of the subblocks by using the motion vectors. When the neighboring reference pixels of the current block are available, the video decoding apparatus calculates, related to top sub-reference blocks and left sub-reference blocks of the reference block, positions of neighboring reference pixels of each top or left sub-reference block. When the neighboring reference pixels of the reference block are available in the calculated positions, the apparatus derives parameters of a linear relation between the neighboring reference pixels of the current block and the neighboring reference pixels of the reference block and generates a prediction block of the current block by applying local illumination compensation to the reference block.

If the sequential split flag is true, the method further includes partitioning the current block into lower blocks by using the sequential quad-tree structure.
