Claim 14:
15. The method of claim 14, wherein
the partition information further indicates the chroma horizontal subsampling factor, a MTT depth indicating whether the chroma block is a MTT node from a MTT split, and a prediction mode type for the chroma block; and
in response to the block size of the chroma block in luma samples divided by the chroma vertical subsampling factor being larger than the minimum allowed chroma QT leaf node size in chroma samples, the method further includes:
determining whether the QT split is disallowed for the chroma block based on the block size of the chroma block in luma samples, the chroma horizontal subsampling factor, the MTT depth, and the prediction mode type.
