Abstract:
A method for video decoding is disclosed. A directional intra prediction mode is decoded (910) for a current block of a picture in a video, said directional intra prediction mode having a direction. Based on said directional intra prediction mode, a first predictor for a sample is accessed (7010), the sample being within said current block. Based on said directional intra prediction mode, a second predictor for said sample, is accessed (7020) said first and second predictors being on a line at least approximating said direction. A sample value of said sample is predicted (7030) by using said first and second predictors; and said sample of said current block is reconstructed (965) based on said predicted sample value.
