Claim 1:
2. The method of claim 1, wherein
the partition information further indicates a multi-type tree (MTT) depth indicating whether the chroma block is a MTT node from a MTT split, a chroma horizontal subsampling factor, and a prediction mode type for the chroma block; and
in response to the block size cbSize of the chroma block in luma samples being larger than the minimum allowed chroma QT leaf node size MinQtSizeC in luma samples, determining that the QT split is disallowed for the chroma block based on at least one of (i) the MTT depth indicating that the chroma block is the MTT node, (ii) the block size cbSize of the chroma block in luma samples divided by the chroma horizontal subsampling factor being less than or equal to 4, and (iii) the prediction mode type indicating that an intra prediction mode and an intra block copy (IBC) mode are allowed.
