HMVC FOR AFFINE MODE AND MOTION VECTOR PREDICTION MODE SBTMVP Russian patent published in 2024 - IPC H04N19/513 

FIELD: physics.

SUBSTANCE: invention relates to encoding and decoding a video image based on motion vectors determined from previously encoded or decoded blocks. Result is achieved by the fact that the device for encoding or decoding blocks of the current image encodes sub-blocks of the first block of the current image. Sub-blocks are encoded or decoded based on motion vectors determined in accordance with motion information data associated with the first block. At the second stage, the set of second movement information data is determined depending on the first movement information data. Said second motion information data is added to a motion information data list which is used to determine motion information data for subsequent blocks of the current image for encoding or decoding.

EFFECT: high efficiency of compressing video image.
