METHOD OF RESIDUAL DIFFERENTIAL PULSE CODE MODULATION FOR EXPANDING HIGH-EFFICIENT VIDEO CODING (HEVC) RANGE Russian patent published in 2017 - IPC H04N19/00 

FIELD: physics.

SUBSTANCE: to implement the method, the same steps of coding and decoding, by residual differential pulse code modulation (DPCM), in the same processing order, are applied to the blocks coded in the internal prediction mode and intermediate prediction mode/IntraBC prediction mode (intraframe block copy mode). The method for propagating intermediate coding by the residual DPCM to the blocks coded in the IntraBC prediction mode. The residual IntraBC is treated with residual DPCM processing in a vertical or horizontal direction.

EFFECT: expanding the range of high-efficient video coding.
