FRAME ENCODING DEVICE, FRAME ENCODING METHOD, FRAME DECODING DEVICE AND FRAME DECODING METHOD Russian patent published in 2022 - IPC H04N19/513 H04N19/52 

FIELD: encoding and decoding technologies.

SUBSTANCE: inventions group relates to technologies for encoding and decoding frames for dividing a frame into blocks and performing prediction. A frame encoding device is proposed for encoding a moving frame using inter-prediction based on inter-prediction information in units of blocks into which each frame of moving frames is divided. The device includes an encoding information storage module, a history-based potentially suitable motion vector predictor candidate extraction module, and a potentially suitable combining candidate extraction module. The spatial motion vector predictor candidate extraction module is configured to extract a motion vector spatial predictor candidate from a block adjacent to the target block and add this motion vector spatial predictor candidate to a list of potential motion vector predictor candidates.

EFFECT: improving encoding efficiency by performing block partitioning suitable for coding and decoding frames.
