US Patent 11909994 Method and apparatus for intra-prediction coding of video data

A method and apparatus for intra-prediction coding of video data are provided. The apparatus includes a decoder that is configured to decode, from a bitstream, a syntax element indicating an intra-prediction type of a current block of the video data, and an intra-predictor that is configured to generate a prediction block for the current block by selectively performing matrix based intra-prediction or regular intra-prediction based on the intra-prediction type of the current block indicated by the syntax element.
