Abstract RU 2787810 C1

FIELD: video encoding.

SUBSTANCE: in the method for video decoding, wherein a bit stream of the encoded video including the current image is received, reverse quantisation is executed for the current block of the current image, and reverse colour conversion is executed for the current block after reverse quantisation; herein, reverse colour conversion for the current block is executed in response to determining that different colour components of the reverse colour conversion are encoded using the same coding unit division tree, and reverse colour conversion is applied for intra-coded blocks.

EFFECT: higher accuracy of signal encoding.
