nts ransform_8x8_mode_flag, pic_scaling_matrix_present_flag second_chroma_qp_index_offset shall not be present in picture parameter sets. The syntax element level_prefix shall not be greater than 15 (when present). The syntax elements pcm_sample_luma[ ], with i = 0..255, and pcm_sample_chroma[i with i 0..2 * MbWidthC * MbHeightC - 1, shall not be equal to 0 (when present). The level constraints specified for the Extended profile in clause A.3 shall be fulfilled. Conformance of a bitstream to the Extended profile is indicated by profile_idc being equal to 88. Decoders conforming to the Extended profile at a specified level shall be capable of decoding all bitstreams in which profile idc is equal to 88 or constraint_set2_flag is equal to 1 and in which level idc represents a level less than or equal to specified level. Decoders conforming to the Extended profile at a specified level shall also be capable of decoding all bitstreams in which profile_idc is equal to 66 or constraint_set0_flag is equal to 1, in which level_idc and constraint_set3_flag represent a level less than or equal to the specified level. A.2.4 High profile Bitstreams conforming to the High profile shall obey the following constraints: Only I, P, and B slice types may be present. NAL unit streams shall not contain nal_unit_type values in the range of 2 to 4, inclusive. Arbitrary slice order is not allowed. Picture parameter sets shall have num_slice_groups_minus1 equal to 0 only. Picture parameter sets shall have redundant_pic_cnt_present_flag equal to 0 only. Sequence parameter sets shall have chroma_format_idc in the range of 0 to 1 inclusive. Sequence parameter sets shall have bit_depth_luma_minus8 equal to 0 only. Sequence parameter sets shall have bit_depth_chroma_minus8 to 0 only. Sequence parameter sets shall have pprime_y_zero_transform_bypass_flag equal to 0 only. The level constraints specified for the High profile in clause A.3 shall be fulfilled. Conformance of a bitstream to the High profile is indicated by profile_idc being equal to
