FIELD: physics.

SUBSTANCE: invention relates to image encoding means. Obtaining value of maximum number of potentially suitable variants of motion vector prediction (MVP) for combination for current block, wherein the current block is predicted using the intra-block copy mode. Setting the value of mvp_10_flag[x0][y0] equal to zero, when the value of the maximum number of potentially suitable MVP variants for the current block is equal to one, where mvp_10_flag[x0][y0] indicates the motion vector predictor index for list 0, where x0, y0 indicate the location (x0, y0) of the upper left discrete luminance sample of the current block relative to the upper left discrete luminance sample of the image. This value mvp_10_flag[x0][y0] is not obtained through analysis from the bitstream. Obtaining, through analysis, value of mvp_10_flag[x0][y0] from bit stream, when the value of the maximum number of potentially suitable MVP variants for the current block is greater than one. Motion vector of the current block is obtained according to mvp_10_flag[x0][y0] and a list of potentially suitable options.

EFFECT: high efficiency of encoding images.
