SYNTAX ELEMENTS FOR VIDEO CODING OR DECODING Russian patent published in 2023 - IPC H04N19/105 

FIELD: video coding.

SUBSTANCE: invention relates to syntax elements for encoding or decoding video. The result is that efficient coding tool signalling is the transfer of information representing the coding tools used for coding, for example, from an encoder device to a receiver device (for example, a decoder or display), so that the appropriate tools are used for the decoding stage. These tools include new segmentation modes, new intra-prediction modes, increased flexibility for sampled adaptive bias, and a new luminance compensation mode for bi-prediction blocks based on a single flag capable of determining whether independent coding trees or general coding trees are used for coding luminance and chrominance blocks, while the single flag mentioned above is inserted into the high-level syntax elements of the frame's encoded data.

EFFECT: increasing the coding efficiency.
