eristic information as specified by the following syntax elements is present in the scalability information SEI message. The value of pr_num_dIds_minusl shall be in the range of 0 to 7, inclusive. pr_dependency_id[i specifies the value of dependency_id of the dependency layer for which the priority layer characteristic information is signalled by the following syntax elements. When i is greater than 0, the value of pr_dependency_id[i shall not be equal to any of the values of pr_dependency_id[_ ] with = - 1). pr_num_minus1| plus 1 specifies the number of priority layers with dependency_id equal to pr_dependency_id[i for which priority layer characteristic information as specified by the following syntax elements is present in the scalability information SEI message. The value of pr_num_minus1[ shall be in the range of 0 to 63, inclusive. specifies the priority identifier pld for a priority layer with dependency_ic equal to or_dependency_i value of pr id[ i ][ shall be in the range of 0 to 63, inclusive. The target access unit set shall contain one or more primary coded VCL NAL units that are associated with dependency id equal to pr_dependency_id[i] and alt_priority_id[i] equal to pr_id[i][j], where the value of lt_priority_id that is associated with a primary coded VCL NAL unit is specified in clause G.13.2.4. When j is greater than 0, the value of pr_id[i][j] shall not be equal to any of the values of with k = 0..(j - 1). For the following specification inside the clause, the priority layer with dependency_id equal to the current value of pr_dependency_id[i] and the priority layer identifier pId equal to the current value of ][ ] is referred to as the current priority layer and the representation of the current priority layer is referred to as the current priority layer representation. pr_profile_level_idc[i[jh indicates the conformance point of the current priority layer representation. pr_profile_level_idc[i] is the exact copy of the three bytes consisting of profile_idc, constraint_set0_flag, constraint set1
