FIELD: information technology. ^ SUBSTANCE: one of a plurality of prediction modes is selected for use in generating a prediction block of a video block of a coding unit, the plurality of prediction modes including unidirectional prediction modes and multi-directional prediction modes which combine at least two unidirectional prediction modes. An encoding device encodes the prediction mode of the current video block based on prediction modes of one or more previously encoded video blocks of the coding unit. A decoding unit receives encoded video data of a video block of a coding unit and decodes the encoded video data to identify one of a plurality of prediction modes for use in generating a prediction block of the video block based on prediction modes of one or more previously decoded video blocks of the coding unit. ^ EFFECT: high efficiency of encoding video blocks based on selecting one or a plurality of prediction modes for use when generating a prediction block of a video block of a coding unit. ^ 84 cl, 8 dwg |
