METHOD AND EQUIPMENT FOR PROCESSING OF VIDEO DATA Russian patent published in 2023 - IPC H04N19/105 H04N19/513 

Abstract RU 2789452 C2

FIELD: video encoding/decoding.

SUBSTANCE: invention relates to the field of encoding/decoding of a video signal by means of the use of mutual prediction. A method for decoding of video data is proposed, which contains: configuration of a list of possible options of a block vectors of the current block, to which a prediction mode based on inter-block copying (hereinafter – IBC) is applied, wherein IBC mode refers to another block in the current frame, and formation of a prediction sample of the current block based on the block vector included in the list of possible options of block vectors. Configuration of the list of possible options of block vectors contains: configuration of a list of possible options of block vectors from a spatial neighboring block, to which IBC prediction mode is applied, and modification of the list of possible options of block vectors based on a possible option of history-based motion vector prediction (HVMP), to which IBC prediction mode is applied, when a number of current possible options of the list of possible options of block vectors is less than the maximum number of possible options.

EFFECT: provision of processing of video data for creation of a list of possible combination options or an option of motion vector prediction in a prediction mode based on a link to current frames (CPR) or based on IBC.
