Abstract
A method and an apparatus are configured for intra prediction coding of video data. An apparatus for decoding video data includes: a decoding unit which obtains, from a bitstream, information on a luma prediction mode and information on a chroma prediction mode of a current coding block; and an intra prediction unit which generates luma prediction samples and chroma prediction samples of the current coding block. The intra prediction unit derives a luma intra prediction type and a luma intra prediction mode of the current coding block on the basis of the information on the luma prediction mode, and determines a chroma intra prediction mode of the current coding block on the basis of the luma intra prediction type and the luma intra prediction mode of the current coding block, and the information on the chroma prediction mode.
