VIDEO CODING METHOD AND DEVICE, AND VIDEO DECODING METHOD AND DEVICE, SHARING SAO PARAMETERS BETWEEN COLOUR COMPONENTS Russian patent published in 2017 - IPC H04N19/86 H04N19/91 

FIELD: physics.

SUBSTANCE: video decoding device is proposed. The device contains an analyzer and a sample compensator. Herewith the analyzer receives slice offset information indicating, whether to apply an offset, according to the offset type, for the current slice. The sample compensator compensates for the samples of the current block from the number of blocks included in the current slice by using the offset parameter of the current block. When the slice offset information indicates that an offset value is applied, the analyzer is configured to perform entropy decoding of the bit stream using the context mode and to obtain the left offset merge information of the current block.

EFFECT: reducing the amount of data by compensating the recovered pixels of the current block by using the offset parameter of the current block.
