VIDEO OR IMAGE ENCODING BASED ON INTRA-BLOCK ENCODING Russian patent published in 2024 - IPC H04N19/11 H04N19/70 H04N19/105 H04N19/593 H04N19/132 H04N19/176 

FIELD: video encoding.

SUBSTANCE: prediction mode for the current block in the current frame is extracted as a prediction mode based on intra-block coding (IBC). Flag information for the IBC prediction mode is generated. A list of candidates for the IBC prediction mode is retrieved, which includes candidate block vectors for the reference block in the current frame. Index information for the block vector of the current block is generated based on the list of possible options for the IBC prediction mode. Residual information is generated for the residual samples of the current block. Image information including flag information, index information and residual information is encoded. The image information includes information regarding the maximum number of possible block vectors included in the candidate list for the IBC prediction mode and information regarding the maximum number of possible motion vector candidates included in the candidate list for the inter-prediction mode, different from said information regarding the maximum number of possible block vector options.

EFFECT: increase of efficiency of video encoding.
