FIELD: video encoding.

SUBSTANCE: bitstream is received that contains the encoded data of the current block and a pointer. The current block is divided by a common boundary into the first subblock and the second subblock. The first sub-block corresponds to the first prediction value, and the second sub-block corresponds to the second prediction value. The common boundary represents the dividing line of the geometric partitioning mode. The pointer is extracted from the bit stream by analysis. An angular parameter and a distance parameter are obtained based on the pointer, where the angular parameter specifies the angle index of the geometric partitioning mode, and the distance parameter specifies the distance index of the geometric partitioning mode. The distance between the set of discrete samples in the current block and the common boundary is determined based on the angular parameter and the distance parameter by checking a preset lookup table. The first weighting coefficient is obtained according to the distance. The second weight coefficient is obtained according to the first weight coefficient. The concatenated prediction value for the current block is obtained by using the first prediction value, the second prediction value, the first weight coefficient, and the second weight coefficient.

EFFECT: improved efficiency of video encoding.
