METHOD OF INTERNAL PREDICTION AND CODER AND DECODER USING IT Russian patent published in 2021 - IPC H04N19/593 H04N19/176 H04N19/117 

FIELD: computing.

SUBSTANCE: Disclosed is a decoding device that performs intra prediction, the device comprises: an entropy decoding module for obtaining mode information for a current block and a prediction module for obtaining an intra prediction mode for the current block based on said mode information, for obtaining neighboring reference samples of the current block and for generating samples prediction of the current block based on said intra prediction mode and adjacent reference samples, wherein the intra prediction mode is horizontal prediction mode, and the prediction module obtains a prediction sample based on the first neighboring reference sample located on the left side of the left boundary of the current block, and performs filtering with respect to the prediction sample based on the second neighboring reference sample located on the upper side of the upper boundary of the current block when the prediction sample is adjacent to the upper boundary of the current block.

EFFECT: provides video encoding and decoding with intra prediction.
