IMAGE DECODING METHOD TO PERFORM INTER FRAME PREDICTION WHEN PREDICTION MODE FOR CURRENT BLOCK CANNOT BE SELECTED AND DEVICE FOR THIS METHOD Russian patent published in 2023 - IPC H04N19/109 H04N19/119 H04N19/139 

FIELD: image decoding.

SUBSTANCE: invention relates to image decoding for performing inter frame prediction when a prediction mode is not ultimately selected for the current block. The result is achieved by performing inter frame prediction by applying a regular combining mode to the current block based on a case in which the MMVD mode, the sub-block combining mode, the CIIP mode, and the segmentation mode in which prediction is performed by dividing the current block into two segments, are not available for the current block.

EFFECT: increasing the coding efficiency.
