1. A method for video decoding, the method comprising:
receiving a video data sequence of encoded video data,
wherein the video data sequence includes a slice and the slice includes coding unit blocks,
wherein the coding blocks are divided into first sub-coding unit blocks,
wherein at least one of the first sub-coding unit blocks is divided into second sub-coding unit blocks, and
wherein one of the divided first or second sub-coding unit blocks is a square block;
decoding an encoding mode corresponding to a sub-coding unit block among the divided first or second sub-coding unit blocks;
performing either an intra prediction or an inter prediction on the corresponding sub-coding unit block based on the decoded encoding mode; and
transforming residual signals of the corresponding sub-coding unit block,
wherein at least one of variable sizes of transform kernels is selectively applied to the corresponding sub-coding unit block,
wherein the at least one of variable sizes of transform kernels is selected according to a size of the corresponding sub-coding unit block, and
wherein the selected variable size of transform kernel is smaller than the sizes of the respective corresponding sub-blocks.
