1445	Missing condition in restriction of sh_picture_header_in_slice_header_flag	martin.m.pettersson		"In JVET-T2001-v2 the following restriction is present in section 7.4.2.4.4:

''When a picture consists of more than one VCL NAL unit, a PH NAL unit shall be present in the PU.''

and the following restriction is present in section 7.4.8: 

''When any of the following conditions is true, the value of sh_picture_header_in_slice_header_flag shall be equal to 0:''
''- The value of sps_subpic_info_present_flag is equal to 1.''
''- The value of pps_rect_slice_flag is equal to 0.''
''- The value of pps_rpl_info_in_ph_flag, pps_dbf_info_in_ph_flag, pps_sao_info_in_ph_flag, pps_alf_info_in_ph_flag, pps_wp_info_in_ph_flag, or pps_qp_delta_info_in_ph_flag is equal to 1.''

To be in line with the first restriction it seems like the second restriction should be extended to include that the sh_picture_header_in_slice_header_flag shall be equal to 0 when there is more than one slice in the picture. A suggestion is to extend the second restriction as follows:

''When any of the following conditions is true, the value of sh_picture_header_in_slice_header_flag shall be equal to 0:''
''- The value of sps_subpic_info_present_flag is equal to 1.''
''- The value of pps_rect_slice_flag is equal to 0.''
''- The value of pps_rpl_info_in_ph_flag, pps_dbf_info_in_ph_flag, pps_sao_info_in_ph_flag, pps_alf_info_in_ph_flag, pps_wp_info_in_ph_flag, or pps_qp_delta_info_in_ph_flag is equal to 1.''
'''''- The value of pps_num_slices_in_pic_minus1 is greater than 0.'''''"	defect	closed	minor		spec	VVC D10 vH	worksforme		ksuehring bbross XiangLi fbossen jvet@…
