  • Publication number: 20240114148
    Abstract: A video encoding method and a video decoding method are provided for adaptively determining a chroma intra-directional prediction mode. When a DM mode is applied for intra prediction of a chroma signal, the video encoding method and the video decoding method adaptively modify the directional mode of a luma block to conform to the characteristics of a chroma block by considering the position and size of the chroma block, the presence of reference samples, and the size of the luma block. The video encoding method and the video decoding method use the modified directional mode for intra prediction of the chroma signal.
