    摘要： The present disclosure relates to video encoding or decoding for splitting a picture into a plurality of tiles in order to encode video efficiently. In one aspect of the present disclosure, a video encoding method for encoding a picture split into a plurality of tiles includes encoding first information indicating whether to merge some of the plurality of tiles; when the first information is encoded to indicate tile merging, generating one or more merge tiles by merging some of the plurality of tiles, each of the merge tiles being defined as one tile; encoding second information indicating tiles merged into each of the merge tiles among the plurality of tiles; and encoding each of the merge tiles as one tile without restriction on encoding dependencies between the tiles merged into each of the merge tiles.

    摘要： Disclosed herein is a method for decoding a video including determining a coding unit to be decoded by block partitioning, decoding prediction syntaxes for the coding unit, the prediction syntaxes including a skip flag indicating whether the coding unit is encoded in a skip mode, after the decoding of the prediction syntaxes, decoding transform syntaxes including a transformation/quantization skip flag and a coding unit cbf, wherein the transformation/quantization skip flag indicates whether inverse transformation, inverse quantization, and at least part of in-loop filterings are skipped, and the coding unit cbf indicates whether all coefficients in a luma block and two chroma blocks constituting the coding unit are zero, and reconstructing the coding unit based on the prediction syntaxes and the transform syntaxes.
