VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS

WIPO Patent Application WO/2020/040619

A1

Proposed is a video decoding method and apparatus which: in the process of video encoding and decoding, acquires chroma intra-prediction mode information on a current chroma block; when the chroma intra-prediction mode information indicates a DM mode, determines a luma block including a luma sample corresponding to a chroma sample located at the bottom-right of the center of the current chroma block; determines a chroma intra-prediction mode of the current chroma block on the basis of an intra-prediction mode of the determined luma block; and performs intra-prediction of the current chroma block on the basis of the determined chroma intra-prediction mode.
