METHOD OF RECONSTRUCTED UNIT FORMATION Russian patent published in 2020 - IPC H04N19/107 H04N19/11 G06T9/00 

FIELD: calculating; counting.

SUBSTANCE: invention relates to the computer equipment. Method of generating a reconstructed unit includes: obtaining an intra-frame prediction mode by using a group of most probable modes (MPM); generation of prediction block by intra-frame prediction mode; generating a residual block, wherein when the left intra prediction mode is equal to the upper intra prediction mode, MPM group includes two non-directed intra-frame prediction modes and vertical mode, if left-frame intra-frame prediction mode is one of two non-directional intra-frame prediction modes, and MPM group includes left mode and two directed intra-frame prediction modes, if left-frame intra-frame prediction mode is intra-frame prediction mode prediction, wherein if only one of the left intra prediction mode and the upper intra prediction mode is available, the MPM group includes an available intra prediction mode and two additional intra prediction modes.

EFFECT: technical result is reduction of duration of internal prediction, as well as reduction of number of coding bits of residual block and alarm bits required for signalling of internal prediction mode.
