Abstract:
A method of video processing is described. The method includes: determining, based on a coding mode of a current video block of a video, whether a position dependent intra prediction combination (PDPC) method is used for coding the current video block based on a first rule, and performing a conversion between the current video block and a coded representation of the video according to the determining, wherein the PDPC method combines neighboring samples with a prediction signal of the current video block to generate a refined prediction signal of the current video block.
