Abstract

Aspects of the disclosure provide a method and an apparatus for video decoding. The method includes decoding (S2310) a first syntax element from a coded video bitstream, the first syntax element indicating whether a chroma component is present in the coded video bitstream or a monochrome sampling is used in the coded video bitstream; determining (S2320) whether to decode a second syntax element for a cross- component adaptive loop filter (CC-ALF) in response to the first syntax element indicating that a chroma component is present in the coded video bitstream; and decoding (S2330) the second syntax element for the CC-ALF based on the first syntax element indicating that the chroma component is present in the coded video bitstream, wherein the decoding of the second syntax element for the CC-ALF is skipped based on the first syntax element indicating that a monochrome sampling is used in the coded video bitstream.
