摘要： A video decoding method and a video decoding apparatus are configured to decode video. To efficiently code residual blocks obtained from block-based motion compensation, a video encoding apparatus and the video decoding apparatus divide a relevant residual block of a current block into two subblocks in a horizontal or vertical direction and encode one residual subblock alone out of the two residual subblocks.

摘要： A video decoding apparatus is provided for decoding a sequence of pictures, some of which have different resolutions. The apparatus decodes, from a high-level syntax structure of the sequence, a first syntax element for specifying a reference size of pictures referring to the high-level syntax structure and a second syntax element for specifying a picture size scaled from the reference size of the picture referring to the high-level syntax structure. The apparatus predicts a current block, by modifying a sample position in a reference picture indicated by a motion vector of the current block based on the first and second syntax elements.

摘要： A method is executed to efficiently operate a bin buffer to limit a bin-to-bit ratio in entropy encoding and decoding related to bitstream generation and parsing. In addition, a method of configuring a list includes various entropy encoding/decoding methods and adaptively uses the entropy encoding/decoding methods for each basic unit of entropy encoding/decoding.
