tra profiles, the conformance of the bitstream to a specified level is indicated by the syntax element as follows: If level_idc is equal to 9, the indicated level is level 1b. Otherwise (level_i is not equal to 9), level_idc is equal to a value of ten times the level number (of the indicated level) specified in Table A-1. A.3.3 Profile-specific level limits a) In bitstreams conforming to the Main, High, Progressive High, Constrained High, High 10, High 4:2:2, High 4:4:4 Predictive, High 10 Intra, High 4:2:2 Intra, High 4:4:4 Intra, or CAVLC 4:4:4 Intra profiles, the removal time of access unit 0 shall satisfy the constraint that the number of slices in picture 0 is less than or equal to Max( PicSizeInMbs, fR * MaxMBPS + MaxMBPS * SliceRate, where Rec. ITU-T H.264 (01/2012) MaxMBPS and SliceRate are the values specified in Tables A-1 and A-4, respectively, that apply to picture 0 and PicSizeInMbs is the number of macroblocks in picture 0. b) In bitstreams conforming to the Main, High, Progressive High, Constrained High, High 10, High 4:2:2, High 4:4:4 Predictive, High 10 Intra, High 4:2:2 Intra, High 4:4:4 Intra, or CAVLC 4:4:4 Intra profiles, the difference between consecutive removal times of access units n and n - 1 with n > 0 shall satisfy the constraint that the number of slices in picture n is less than or equal to MaxMBPS * (t,(n)-t,(n-1)) - - - SliceRate, where MaxMBPS and SliceRate are the values specified in Tables A-1 and A-4, respectively, that apply to picture n. In bitstreams conforming to the Main, High, Progressive High, High 10, High 4:2:2, High 4:4:4 Predictive profiles, sequence parameter sets shall have direct_8x8_inference_flag equal to 1 for the levels specified in Table A-4. NOTE 1 - direct x8 inference flag is not relevant to the Baseline, Constrained Baseline, Constrained High, High 10 Intra, High 4:2:2 Intra, High 4:4:4 Intra, and CAVLC 4:4:4 Intra profiles as these profiles do not allow B slice types, and direct_8x8_inference_flag is equal to 1 for all levels of the Extended profile. d)
