Abstract
A method of decoding JVET video that includes receiving a bitstream indicating how a coding tree unit was partitioned into coding units, and parsing said bitstream to generate at least one predictor based on an intra prediction mode signaled in the bitstream, the intra prediction mode selected from a plurality of intra prediction modes for calculating a prediction pixel P[x,y] at coordinate x,y for the coding unit. A number of intra prediction modes available for coding the coding unit are reduced by replacing two or more non-weighted intra prediction modes by a weighted intra prediction mode.
