INTERNAL PREDICTION METHOD AND ENCODER AND DECODER USING SAME Russian patent published in 2015 - IPC H04N19/593 

FIELD: physics.

SUBSTANCE: method comprises outputting a prediction mode for a current unit, generating a prediction unit which includes a prediction sample by deriving a prediction sample for the current unit based on the prediction mode. In the method, the prediction mode is an angular prediction mode for internal prediction; generation of the prediction unit includes filtering the prediction sample not located in the direction of the angular prediction mode among prediction samples adjacent to the left boundary of the prediction unit, prediction samples adjacent to the upper boundary of the prediction unit; prediction sample filtering is carried out based on a reference sample not located in the direction of the angular prediction mode.

EFFECT: high efficiency of compressing video.
