Abstract:
1. A decoding method, the method comprising the steps of: extracting first information in a bitstream; determining a chroma component intra prediction mode for a current block according to the first information, the first information comprises information for indicating whether the chroma component intra prediction mode is a DM mode or whether the chroma component intra prediction mode is an LM mode; when the chroma component intra prediction mode cannot be determined according to the first information, then extracting second information in the bitstream, wherein the second information is carried by an FL code having 2 binary symbols; and determining the chroma component intra prediction mode according to the second information, the second information is used to indicate a remaining mode of the chroma component intra prediction mode, wherein the remaining mode is one of available chroma component intra prediction modes other than a mode that may be determined according to the first information.
