Claim 2:
3. The method of claim 1, wherein
the chroma subsampling format is 4:2:0;
the at least one luma sample includes four luma samples that are a top-left sample, a top-right sample, a bottom-left sample, and a bottom-right sample;
the chroma sample type is one of six chroma sample types 0-5 indicating six relative positions 0-5, respectively, and the six relative positions 0-5 of the chroma sample correspond to a left-center position between the top-left and the bottom-left samples, a center position of the four luma samples, a top left position co-located with the top-left sample, a top-center position between the top-left and the top-right samples, a bottom left position co-located with the bottom-left sample, and a bottom-center position between the bottom-left and the bottom-right samples, respectively; and
the determining the filter shape includes determining the filter shape of the cross-component filter based on the chroma sample type.
