METHOD AND DEVICE FOR DETERMINATION OF REFERENCE IMAGES FOR EXTERNAL PREDICTION Russian patent published in 2018 - IPC H04N19/503 H04N19/176 H04N19/577 

FIELD: data processing.

SUBSTANCE: invention relates to video encoding and decoding. Device for restoring the current image block comprises: a processor configured to determine the depth of the current encoding unit based on separation information, determining the index of the first context model according to the depth of the current encoding unit and obtaining a first bit indicating, whether the external prediction of the current block in the current coding unit is bidirectional prediction or unidirectional prediction; if the first bit indicates that the external prediction of the current block is unidirectional prediction, processor is configured to obtain a second bit indicating whether the external prediction is the first unidirectional prediction or the second unidirectional prediction, and restoring the current block by performing one of bidirectional prediction, first unidirectional prediction and a second unidirectional prediction according to at least one of the first bit and the second bit.

EFFECT: high efficiency of video decoding.
