IMAGE DECODING DEVICE USING DIFFERENTIAL ENCODING Russian patent published in 2022 - IPC H04N19/103 H04N19/593 

FIELD: imaging technology.

SUBSTANCE: invention relates to the field of video encoding and decoding using the differential encoding method performed in the conversion skip mode. A video decoding method is proposed for restoring the current block encoded using an intra-prediction, which includes decoding direction information from the bitstream indicating the direction of differential encoding applied to the residual block of the current block, generating a residual block from residual signals by restoring and using information about residual signals from the bitstream and using direction information, reverse quantization of the modified residual block, generating a prediction block for the current block by means of an intra-prediction and restoring the current block by adding a prediction block and a reverse quantized residual block.

EFFECT: increase in the efficiency of video encoding and decoding.
