Abstract

A method of encoding a block of a picture into a video bitstream is provided. The method is performed by a video encoder and comprises encoding a first block of the picture, determining an intra-prediction mode for a second block of the picture, for which second block the intra-prediction is made from pixels in the first block along a non-straight line, encoding the second block using the determined intra-prediction mode, and signaling syntax elements for the second block in the video bitstream.
