1091	Unnecessary description of default behavior	deluxan		"The intra_subpartitions_split_type syntax element is described as

''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.''

It can be seen that the default behaviour of the element when it is not present depends on cbHeight and cbWidth. This was necessary in the past, but after the adoption of JVET-N0308 ISP can only be used if both cbWidth and cbHeight are less than or equal to MaxTbSizeY. Therefore, the default behavior when it is not present is unnecessary and therefore it can be simplified to the following:

''When intra_subpartitions_split_flag[ x0 ][ y0 ] is not present, it is inferred to be 0.''"	defect	closed	minor		spec		duplicate		ksuehring bbross XiangLi fbossen jvet@…
