o_present_flag[ is equal to 1) are identical to the values of the same decoded samples that would be obtained by decoding all layer representations, of the primary coded pictures inside the target access unit set, that have DQId less than or equal to 16 * dependency_id[i] id| and temporal_ less than or equal to temporal_id[i]. With picSubset being the set of the primary coded pictures of the current scalable layer representation that contain any VCL NAL unit with dependency_i equal to dependency_id[i], the following applies: If ub_pic_layer_flag[ i ] is equal to 1 (iroi_division_info_present_flag| is equal to 0), the following is specified: 1. Let picLRepSubset be the set of primary coded pictures that is formed by all the layer representations, of the target access unit set, that contain any primary coded VCL NAL unit present in the set of pictures picSubset. NOTE picSubset is a proper subset of picLRepSubset. picSubset only contains the primary coded slices of the current (sub-picture) scalable layer representation, picLRepSubset contains all primary coded slices of the corresponding layer representations (i.e. the complete layer representations that contain any slice of picSubset). 2. exact_sample_value_match_flag[ equal to 1 indicates that the value of each decoded sample inside the sub-picture area for decoding the picture set picSubset is identical to the value of the same decoded sample that would be obtained by decoding the picture set picLRepSubset. exact_sample_value_match_flag| equal to 0 indicates that the value of any decoded sample inside the sub-picture area for decoding the picture set picSubset may or may not be identical to the value of the same decoded sample that would be obtained by decoding the picture set picLRepSubset. Otherwise (sub_pic_layer_flag[i is equal to 0 and roi_division_info_present_flag[ is equal to 1), for each particular IROI, the following is specified: 1. Let picIROISubset be the set of primary coded VCL NAL units that is obtained by removing all the VCL NAL units from the
