Abstract RU 2770423 C1

FIELD: encoding.

SUBSTANCE: invention relates to video sequence encoding tools. The initial information on the motion of the current image block is obtained. Sample values of at least two candidate blocks of the reference image, corresponding to the current image block, are obtained in accordance with the initial motion information. The bit depth of the sample values of each candidate block of the reference image is limited to a preset bit depth. The verified motion information is obtained based on the limited sample values of at least two blocks of the reference image. The prediction image block of the current image block is determined in accordance with the verified motion information. The stage of limiting the bit depth of the sample values of each block of the reference image to a preset depth includes a sub-stage of executing a right shift of the bit depth of the sample values of each block of the reference image by the value (b-d), wherein b is the bit depth of the sample values of each block of the reference image, d is the preset bit depth, and b is greater than d.

EFFECT: increase in the efficiency of encoding.
