SIMPLIFIED METHOD FOR SIGNALLING FOR THE MODE OF AFFINE LINEAR WEIGHTED INTRA PREDICTION Russian patent published in 2022 - IPC H04N19/44 H04N19/159 H04N19/11 H04N19/105 H04N19/176 H04N19/186 H04N19/119 

FIELD: video data processing.

SUBSTANCE: invention relates to video encoding tools. The prediction information for the current block is decoded in the current image, said image being part of the encoded video sequence. Said prediction information indicates whether the current block is encoded using matrix-based intra prediction (MIP). In response to the prediction information indicating that the current block is encoded using MIP, the index of the MIP mode is determined, wherein the index of the MIP mode indicates one of a set of MIP modes, and the current block is reconstructed according to said one of the set of MIP modes. Herein, in response to the prediction information indicating the current block being encoded using MIP, a list of potential modes is formed, including at least one fixed potential mode, wherein the list of potential modes constitutes a preset subset of the set of MIP modes.

EFFECT: increased efficiency of video decoding.
