METHOD AND DEVICE FOR MOTION INFORMATION STORAGE Russian patent published in 2023 - IPC H04N19/137 H04N19/132 H04N19/543 H04N19/105 

FIELD: video coding.

SUBSTANCE: current block consists of the first subblock and the second subblock. The first sub-block and the second sub-block are separated by a common boundary, which is the dividing line of the geometric partitioning mode. The first sub-block corresponds to the first motion information, and the second sub-block corresponds to the second motion information. Moreover, the first motion information contains a motion vector with uni-prediction for the first sub-block, and the second motion information contains a motion vector with uni-prediction for the second sub-block. The distance between the set of discrete samples in the current block and the common boundary is determined as follows: distFromLine=((x<<N)+K)*P1+((y<<N)+K)*P2−P3, where P1, P2 and P3 are the first computational parameter, the second computational parameter, and the third computational parameter, respectively, distFromLine represents the distance, K is a non-negative integer, N=1, x represents the horizontal coordinate of the target position in the sample set, y represents the vertical coordinate of the target position in the rectangular coordinate system.

EFFECT: increase in the efficiency of video coding.
