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