DECODER, ENCODING METHOD AND DECODING METHOD Russian patent published in 2023 - IPC H04N19/513 H04N19/119 H04N19/176 

FIELD: encoding and decoding.

SUBSTANCE: first table is selected from tables, each of which associates indices with the corresponding correction values, each of the tables is used to change the motion vector of the current block included in the image. The parameter is written to the bitstream, the parameter indicating the first index from among the indices in the first table. The correction value associated with the first index is identified. The motion vector is changed by a correction value in a predetermined direction. The current block is encoded based on the changed motion vector. The difference between the two correction values of the correction values varies from table to table, with two correction values in each of the tables associated with the same two indices.

EFFECT: increase of efficiency of video encoding.
