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

FIELD: frames encoding and decoding.

SUBSTANCE: inventions group relates to technologies for encoding and decoding frames for dividing a frame into blocks and performing prediction. A frame encoding apparatus for encoding a moving frame using inter-prediction based on inter-prediction information in units of blocks into which each frame from among the moving frames is divided is proposed. The device includes an encoding information storage module, a history-based motion vector predictor retrieval module, a history-based potentially candidate combining module. At the same time, these modules for extracting potentially suitable variants of motion vector predictors and combining define potentially suitable variants included in the list of potentially suitable variants of motion vector predictors based on history, as potentially suitable variants of motion vector predictors based on history or potentially suitable variants for combining based on history. with reference to potentially viable variants included in the list of potentially viable variants of motion vector predictor based on history, in different orders from each other.

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