VIDEO DECODING METHOD Russian patent published in 2017 - IPC H04N19/129 H04N19/139 H04N19/105 

FIELD: physics.

SUBSTANCE: video decoding method includes the steps of obtaining the quantized transformation coefficients of the current block and the reference image index from the bitstream; obtaining the transformation coefficients by inverse quantizing the quantized transformation coefficients; obtaining the difference samples of the current block by inverse transforming the transformation coefficients; obtaining the spatial vector-candidate for the neighboring space block movement relative to the current block; selecting the associated image related to the temporary vector-candidate of the current block movement, based on the reference image index; obtaining the temporal vector-candidate of the current block movement on the associated block. The associated block is included in the associated image; generating the list of the movement vector-candidates containing a spatial movement vector-candidate and a temporary movement vector-candidate; determining the movement vector predictor based on the list of the movement vector-candidates and the candidate index of the current block. The candidate index indicates one of the movement vector-candidates contained in the list of the movement vector-candidates; obtaining the prediction samples of the current block using the movement vector predictor; and reconstructing the current block using the prediction samples and the difference samples of the current block.

EFFECT: efficient video decoding.
