Correction of wrong reference on VVC Annex C.4 regarding DpbOutputInterval constraint

[jhlim]

DpbOutputInterval constraint in the following text seems to be referencing the wrong part.

• Related subclause: VVC Annex C.4 Bitstream conformance

"9. The value of DpbOutputInterval[ n ] as given by Formula (1605), which is the difference between the output times of a picture and the first picture following it in output order and having PictureOutputFlag equal to 1, shall satisfy the constraint expressed in subclause A.4.1 for the profile, tier and level specified in the bitstream using the decoding process specified in Clauses 2 through 9."

The actual constraint applied on DpbOutputInterval can be found in A.4.2 not in A.4.1. as described in following:

"b) The difference between consecutive output times of pictures of different AUs from the DPB, as specified in subclause C.3.3, shall satisfy the constraint that DpbOutputInterval[ n ] is greater than or equal to Max( AuSizeMaxInSamplesY[ n ] / MaxLumaSr, FrVal ), where MaxLumaSr is the value specified in Table A.3 for AU n, provided that AU n has a picture that is output and AU n is not the last AU of the bitstream that has a picture that is output."

The same issue exists in the HEVC spec text also.

Good catch, thanks! Added to the errata report in JVET-AI1004 (and to be fixed later in VVCv4 and HEVCv11).
