VIDEO DECODING METHOD Russian patent published in 2020 - IPC H04N19/44 H04N19/513 H04N19/52 

FIELD: information technology.

SUBSTANCE: invention can be used for decoding video signal. Method comprises obtaining an associated reference index from an input bit stream, wherein the associated reference index is reported to identify an associated image relating to the current block; determining an associated image based on the associated reference index; obtaining a temporal prediction motion vector of the current block by scaling the motion vector of the associated block in the associated image; generating a candidate motion vectors list including a temporal prediction motion vector; obtaining a prediction block by performing inter-frame prediction for the current block based on the generated candidate motion vectors list; obtaining a residual block by performing inverse quantisation and inverse transformation of transformation coefficients relating to the current block; and restoring current block using prediction unit and residual unit.

EFFECT: technical result is reduced amount of memory required during decoding.
