ied in Annex C), BitRate[ SchedSelIdx and CpbSize[ SchedSelIdx ] are given as follows: - If vui_ext_nal_hrd_parameters_present_flag[i] is equal to 1, BitRate[ SchedSelIdx ] and CpbSize[ SchedSelIdx are given by Equations E-37 and E-38, respectively, using the syntax elements of hrd_parameters() syntax structure immediately follows vui_ext_nal_hrd_parameters_present_flag[ i]. Otherwise (vui_ext_nal_hrd_parameters_present flag[ i ] is equal to 0), BitRate[SchedSelldx and CpbSize[ SchedSelIdx ] are inferred as specified in clause E.2.2 for NAL HRD parameters. MaxBR and MaxCPB are specified in Table A-1 in units of cpbBrNalFactor bits/s and cpbBrNalFactor bits, respectively. The bitstream shall satisfy these conditions for at least one value of SchedSelIdx in the range 0 to cpb_cnt_minus1, inclusive. In bitstreams conforming to the Scalable Baseline, Scalable Constrained Baseline, Scalable High, Scalable Constrained High, or Scalable High Intra profiles, the sum of the NumBytesInNALunit variables for access unit 0 is less than or equal to 384 * (Max( svcPicSizeInMbs, fR * MaxMBPS) + MaxMBPS * / MinCR, where MaxMBPS and MinCR are the values specified in Table A-1 that apply to picture 0. In bitstreams conforming to the Scalable Baseline, Scalable Constrained Baseline, Scalable High, Scalable Constrained High, or Scalable High Intra profiles, the sum of the NumBytesInNALunit variables for access unit n with n > 0 is less than or equal to 384 * MaxMBPS * t(n)-t(n-1)) MinCR, where MaxMBPS and MinCR are the values specified in Table A-1 that apply to picture n. In bitstreams conforming to Scalable Baseline or Scalable Constrained Baseline profile, picture parameter sets shall have entropy_coding_mode_flag equal to 0 and transform_8x8_mode_flag equal to 0 for level 2.1 and below. 1) In bitstreams conforming to Scalable Baseline, Scalable Constrained Baseline, Scalable High, Scalable Constrained High, and Scalable High Intra profiles, when PicSizeInMbs is greater than 1620 for DQId equal to Rec.
