MOVING IMAGE ENCODING DEVICE, MOVING IMAGE ENCODING METHOD, MOVING IMAGE ENCODING PROGRAM, MOVING IMAGE DECODING DEVICE, MOVING IMAGE DECODING METHOD AND MOVING IMAGE DECODING PROGRAM Russian patent published in 2022 - IPC H04N19/52 H04N19/70 

FIELD: data processing.

SUBSTANCE: group of inventions relates to video data processing technologies. Disclosed is a moving frame coding device. Device comprises a module for extracting potentially suitable versions of spatial information of movement. Device also includes a module for extracting potentially suitable versions of motion information based on history. Module for extracting potentially suitable versions of spatial information of movement is made with the possibility of extracting a potentially suitable version of the spatial motion information from the motion information of a block adjacent to the target decoding block in the spatial domain. Module for extracting potentially suitable versions of motion information based on the history preferably extracts old motion information without comparing the motion information with a potentially suitable version of spatial information of motion.

EFFECT: reduction of data processing load on video data encoding/decoding devices.
