AFFINE LINEAR WEIGHTED INTERNAL PREDICTION IN VIDEO ENCODING Russian patent published in 2024 - IPC H04N19/11 H04N19/159 H04N19/176 

FIELD: physics.

SUBSTANCE: invention relates to video encoding means. Context for the syntax element of affine linear weighted internal prediction, ALWIP, is determined, wherein the syntax ALWIP element indicates whether the current block of video data is encoded using ALWIP. Based on the fact that the overlying neighbouring block is in another coding tree unit, CTU, relative to the current block, the overlying neighbouring block is determined as not available for context determination, value of syntax ALWIP-element for above-lying neighbouring block is used to determine said context. Overlying neighbouring block is an overlying neighbouring node relative to the current block, and the context for the syntax ALWIP element identifies the probabilities that the bin has specific values. Syntactic ALWIP element is encoded based on context. Method includes performing a process of extracting most probable modes, MPM, which extracts one or more MPMs for the current block, wherein the current block is not encoded using ALWIP.

EFFECT: higher efficiency of video encoding.
