For the VCL HRD parameters, BitRate[ SchedSelIdx ] <= cpbBrVclFactor * MaxBR CpbSize[ SchedSelIdx <= cpbBrVclFactor *MaxCPB for at least one value of SchedSelIdx, where cpbBrVclFactor is equal to 1250. With vui_mvc_vcl_hrd_parameters_present_flag[ being the syntax element, in the MVC VUI parameters extension of the active MVC sequence parameter set, that is associated with the VCL HRD parameters that are used for conformance checking (as specified in Annex C), BitRate[SchedSelldx ] and CpbSize[ SchedSelIdx ] are given as follows: If vui_mvc_vcl_hrd_parameters_present_flag equal to 1, SchedSelIdx ] CpbSize[ SchedSelIdx ] are given by Equations E-37 and E-38, respectively, using the syntax elements of hrd parameters() syntax structure immediately follows vui_mvc_vcl_hrd_parameters_present_flag. Otherwise (vui_mvc_vcl_hrd_parameters_present_flag equal to 0), BitRate[ SchedSelIdx and CpbSize[ SchedSelIdx are inferred as specified in clause E.2.2 for VCL HRD parameters. Rec. ITU-T H.264 (01/2012) MaxBR and MaxCPB are specified in Table A-1 in units of cpbBrVclFactor bits/s and cpbBrVclFactor bits, respectively. The bitstream shall satisfy these conditions for at least one value of SchedSelIdx in the range 0 to cpb_cnt_minus1, inclusive. parameters, BitRate[ SchedSelIdx ] <= cpbBrNalFactor * MaxBR CpbSize[ SchedSelIdx ] cpbBrNalFactor *MaxCPB for at least one value of SchedSelIdx, where cpbBrNalFactor is equal to 1500. With vui_mvc_nal_hrd_parameters_present_flag[i] being the syntax element, in the MVC VUI parameters extension of the active MVC sequence parameter set, that is associated with the NAL HRD parameters that are used for conformance checking (as specified in Annex C), BitRate[SchedSelldx ] and CpbSize[ SchedSelIdx ] are given as follows: vui_mvc_nal_hrd_parameters_present_flag equal to 1, BitRate[SchedSelldx] ] CpbSize[ SchedS
