Abstract
Official abstract text for this publication.
Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for video decoding, the apparatus comprising: a receiver configured to receive 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 unit 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; and a decoder configured to: decode an encoding mode corresponding to a sub-coding unit block among the divided first or second sub-coding unit blocks; perform either an intra prediction or an inter prediction on the corresponding sub-coding unit block based on the decoded encoding mode; and transform 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 at least one of variable sizes of transform kernels is smaller than the sizes of the respective corresponding sub-blocks.
