Abstract

A video coding method that uses multiple reference lines for cross-component prediction is provided. A video coder receives data for a block of pixels to be encoded or decoded as a current block of a current picture. A video coder derives a linear model based on luma and chroma samples from one or more reference lines that are selected from a plurality of reference lines neighboring the current block at different distances. A video coder applies the linear model to luma samples of the current block to obtain predicted chroma samples of the current block. The video coder encodes or decodes the current block by using the predicted chroma samples of the current block. The linear model may be derived using luma and chroma samples of only one selected reference line, or of two or more selected reference lines.
