ccess unit removal time specified in Annex C of the Recommendation International Standard. rewriting_max_bitrate[ i I[ ] indicates an upper bound for the bit rate of the alternative set of access units obtained by converting the representation of the current scalable layer, in any one-second time window of access unit removal time as specified in Annex C. The upper bound for the bit rate of the alternative set of access units in bits per second is given by BitRateBPS(rewriting_max_bitrate[i][j]) with the function BitRateBPS() being specified in Equation G-370. Rec. ITU-T H.264 (01/2012) For the following specification, the terms priority layer, dependency layer, and priority layer representation are defined as follows. A priority layer consists of the set of primary coded VCL NAL units, inside the target access unit set, that are associated with a particular value of dependency_ id and a value of lt_priority_id[ as specified in clause G.13.2.4, that is less than or equal to a particular priority identifier pld and the set of associated non-VCL NAL units. A priority layer is associated with a particular value of dependency id and a particular priority layer identifier pld. When present in the target access unit, the following NAL units are associated non-VCL NAL units for a priority layer: sequence parameter set, subset sequence parameter set, and picture parameter set NAL units that are referenced in the VCL NAL units of the priority layer (via the syntax element pic_parameter_set_id), sequence parameter set extension NAL units that are associated with a sequence parameter set NAL unit referenced in the VCL NAL units of the priority layer, filler data NAL units that belong to an access unit containing VCL NAL units of the priority layer and are associated with the same values of dependency_id and quality_id as the VCL NAL units of the priority layer in the same access unit, SEI NAL units containing SEI messages, with payloadTyp not equal to 24, 28, or 29, that apply to subsets of the bitstream that contain one or
