METHOD AND DEVICE FOR DETERMINATION OF SUPPORTING IMAGES FOR EXTERNAL PREDICTION Russian patent published in 2017 - IPC H04N19/503 H04N19/176 H04N19/577 

FIELD: physics.

SUBSTANCE: method of restoring the current image block comprises the steps of: determining the depth of the current coding unit based on the separation information; the index of the first context model is determined according to the depth of the current coding unit; first bit indicating whether the external prediction of the current block is bidirectional or unidirectional prediction is obtained by using the index of said first context model; if the first bit indicates that the external prediction of the current block is unidirectional prediction, a second bit is obtained indicating whether the outer prediction is the first or second unidirectional prediction, by using the index of the second context model; and reconstructing the current block by performing one of the bidirectional prediction, the first or second unidirectional prediction.

EFFECT: increasing the efficiency of video decoding.
