FRAME DECODING DEVICE, A METHOD FOR DECODING FRAMES AND A PROGRAM FOR DECODING FRAMES Russian patent published in 2022 - IPC H04N19/52 H04N19/105 H04N19/46 

FIELD: imaging technology.

SUBSTANCE: invention relates to the field of encoding and decoding frames. The proposed frame decoding device includes a module for extracting spatial potentially suitable options, made with the ability to extract a spatial potentially suitable option from the information of the inter-prediction of the block adjacent to the target decoding block, and register the extracted spatial potentially suitable option as a potentially suitable option in the first list of potentially suitable options, a module for extracting potentially suitable options based on the background, made with the ability to generate a second list of potentially suitable options by adding a potentially suitable option based on the background included in the list of potentially suitable options based on the background as a potentially suitable option to the first list of potentially suitable options, a module for selecting potentially suitable options, made with the ability to select a potentially suitable option from potentially suitable options included in the second list of potentially suitable options; and an inter-prediction module, made with the ability to perform an inter-prediction using a potentially suitable choice option. The module for extracting potentially suitable options based on the background switches between whether or not a potentially suitable option based on the background is added, overlapping a potentially suitable option included in the first list of potentially suitable options, in accordance with the prediction mode.

EFFECT: increase in the encoding efficiency by performing block splitting, suitable for encoding and decoding frames.
