Abstract:
A method for video processing is provided. The method includes determining, for a conversion between a current video block of a video that is a chroma block and a coded representation of the video, parameters of a cross-component linear model using a parameter table whose entries are retrieved according to two chroma sample values and two luma sample values; and performing the conversion based on the determining.
