摘要： Devices, systems and methods for digital video coding, which includes simplified cross-component prediction, are described. In a representative aspect, a method for video coding includes receiving a bitstream representation of a current block of video data including at least one luma component and at least one chroma component, predicting, using a linear model, a first set of samples of the at least one chroma component based on a second set of samples that is selected by sub-sampling samples of the at least one luma component, and processing, based on the first and second sets of samples, the bitstream representation to generate the current block. In another representative aspect, the second set of samples are neighboring samples of the current block and are used for an intra prediction mode of the at least one luma component.
