Abstract
Disclosed herein is a video decoding method. The video decoding method includes: obtaining a chroma residual joint flag of a current block indicating whether or not a chroma residual joint mode is applied to the current block; obtaining, from a bitstream, a transform skip mode flag for a luma component of the current block and a transform skip mode flag for a first chroma component; when the chroma residual joint flag indicates that a chroma residual joint mode is applied to the current block, determining whether or not a transform skip mode is applied to a second chroma component of the current block, according to the transform skip mode flag for the first chroma component; and, when the chroma residual joint flag indicates that a chroma residual joint mode is not applied to the current block, obtaining, from the bitstream, a transform skip mode flag for the second chroma component of the current block.
