Claim 15:
16. An apparatus for video encoding, comprising processing circuitry configured to:
determine whether a block size cbSize of a chroma block in luma samples is less than or equal to a minimum allowed chroma quaternary tree (QT) leaf node size MinQtSizeC in luma samples such that cbSize <=MinQtSizeC;
in response to the block size cbSize of the chroma block in luma samples being less than or equal to the minimum allowed chroma QT leaf node size MinQtSizeC in luma samples, determine that a QT split is disallowed for the chroma block; and
generate partition information indicating that a chroma coding tree structure in a dual tree is applied to the chroma block, the partition information further indicating the block size cbSize of the chroma block in luma samples and the minimum allowed chroma QT leaf node size MinQtSizeC in luma samples, the MinQtSizeC indicating a minimum allowed chroma block size for QT splitting.
