FRAME ENCODING DEVICE, FRAME ENCODING METHOD, FRAME DECODING DEVICE AND FRAME DECODING METHOD Russian patent published in 2022 - IPC H04N19/52 H04N19/105 

FIELD: imaging technology.

SUBSTANCE: invention relates to means for encoding and decoding frames. All potentially suitable options based on the background are filled in on the list of potentially suitable options for predictors of motion vectors based on the background with at least a predefined motion vector and a reference index. A list of potentially suitable unification options is formed, including at least a motion vector and a reference index of the block adjacent to the target coding block as a potentially suitable unification option. A potentially suitable variant based on the background is added, included in the list of potentially suitable variants of predictors of motion vectors based on background, to the list of potentially suitable variants of unification as a potentially suitable variant of unification and a second list of potentially suitable variants of unification is derived. A potentially suitable combination option is selected from the second list of potentially suitable combination options as a potentially suitable combination option for selection.

EFFECT: increase the efficiency of encoding frames.
