Description

In 7.4.11.5 Coding unit semantics, there is the description about ISP implicit split when cbHeight or cbWidth is greater than MaxTbSizeY. However the maximum CU size of ISP was limited to MaxTbSizeY x MaxTbSizeY by the adoption of JVET-N0308. So, the description should be removed as follows (this processing has already been removed in VTM);

intra_subpartitions_split_flag[ x0 ][ y0 ] specifies whether the intra subpartitions split type is horizontal or vertical. When intra_subpartitions_split_flag[ x0 ][ y0 ] is not present, it is inferred as follows:
– If cbHeight is greater than MaxTbSizeY, intra_subpartitions_split_flag[ x0 ][ y0 ] is inferred to be equal to 0.
– Otherwise (cbWidth is greater than MaxTbSizeY), intra_subpartitions_split_flag[ x0 ][ y0 ] is inferred to be equal to 1.
