METHODS OF DECODING OR ENCODING PREDICTION MODE, DECODING OR ENCODING APPARATUS AND DATA CARRIER Russian patent published in 2023 - IPC H04N19/50 

FIELD: video encoding.

SUBSTANCE: invention relates to methods for decoding or encoding a prediction mode, an apparatus for decoding or encoding video. The technical result is to increase the efficiency of decoding the prediction mode. The result is achieved in that, in response to determining that the merge mode is enabled for the current block and the current candidate prediction mode is enabled for the current block, the method includes: obtaining enable states of one or more prediction modes to be bypassed; decoding indication information of the current candidate prediction mode from the code stream in response to determining that the enabled candidate prediction mode is present in the prediction modes to be bypassed; and directly determining that the current candidate prediction mode is used for the current block without decoding indication information of the current candidate prediction mode from the code stream in response to determining that none of the prediction modes to be bypassed are enabled.

EFFECT: increasing the efficiency of decoding the prediction mode.
