Abstract
A method and an apparatus are disclosed for coding an intra-prediction mode for each chroma component. In the disclosed embodiments, a video decoding device decodes, from a bitstream, first intra-prediction mode information for a first chroma channel of the current chroma block. The video decoding device decodes, from the bitstream, second intra-prediction mode information for a second chroma channel of the current chroma block. Here, the first intra-prediction mode information includes at least one of a first CCLM (cross-component linear model) mode flag, a first CCLM mode index, and a first chroma intra-prediction mode indicator, and the second intra-prediction mode information includes at least one of a second CCLM mode flag, a second CCLM mode index, and a second chroma intra-prediction mode indicator.
