Abstract
The present disclosure provides a video data processing method for cross-component sample adaptive offset. The method includes receiving a bitstream; determining a category index of a target chroma sample, wherein the category index is determined based on a first reconstructed value associated with a co-located luma sample and a second reconstructed value associated with the target chroma sample; decoding an index indicating an offset corresponding to the category index from the bitstream; determining the offset based on the index; and adding the offset to a third reconstructed value associated with the target chroma sample.
