Issue of subpic ID mapping present

Reported by: jiechen Owned by:
Priority: minor Milestone: VVC D7 vC
Component: spec Version: VVC D7 vE
Keywords: Cc: ksuehring, bbross, XiangLi, fbossen, jvet@…


In the VVC draft7-vE, sps_subpic_id_present_flag is always signaled in SPS regardless of the value of subpics_present_flag. It might be a type, sps_subpic_id_present_flag signaling should be on condition of subpics_present_flag. The spec. fixing is as follows

seq_parameter_set_rbsp( ) {

if( subpics_present_flag ) {

for( i = 0; i <= sps_num_subpics_minus1; i++ ) {

subpic_ctu_top_left_x[ i ]
subpic_ctu_top_left_y[ i ]
subpic_width_minus1[ i ]
subpic_height_minus1[ i ]
subpic_treated_as_pic_flag[ i ]
loop_filter_across_subpic_enabled_flag[ i ]


} (remove this braces)

if( sps_subpics_id_present_flag ) {

if( sps_subpics_id_signalling_present_flag ) {

for( i = 0; i <= sps_num_subpics_minus1; i++ )

sps_subpic_id[ i ]



} (add this braces)
