 100. Decoders conforming to the High profile at a specific level shall be capable of decoding all bitstreams in which either or both of the following conditions are true: (profile_idc is equal to 77 or constraint_set1_flag is equal to 1) and the combination of level_idc and constraint_set3_flag represent a level less than or equal to the specified level, profile_idc is equal to 100 and level_ide represents a level less than or equal to the specified level. NOTE - The value 100 for profile_idc indicates that the bitstream conforms to the High profile as specified in this clause. When profile idc is equal to 100 and constraint_set3_flag is equal to 1, this indicates that the bitstream conforms to the High profile and additionally conforms to the constraints specified for the High 10 Intra profile in clause A.2.8. For example, such a bitstream must have bit depth luma minus8 equal to 0, have bit_depth_chroma_minus8 equal to 0, obey the MinCR, MaxBR and MaxCPB constraints of the High profile, contain only IDR pictures, have max_num_ref_frames equal to 0, have dpb_output_delay equal to 0, and obey the maximum slice size constraint of the High 10 Intra profile. A.2.4.1 Progressive High profile Bitstreams conforming to the Progressive High profile shall obey all constraints specified in clause A.2.4 for the High profile, and shall additionally obey the constraint that sequence parameter sets shall have frame_mbs_only_flag equal to 1. Conformance of a bitstream to the Progressive High profile is indicated by profile_idc being equal to 100 with constraint_set4_flag being equal to 1. Decoders conforming to the Progressive High profile at a specific level shall be capable of decoding all bitstreams in which one or more of the following conditions is true: (profile_idc is equal to 66 or constraint_set0_flag is equal to 1), constraint_setl_flag is equal to 1, and the combination of level ide and constraint_set3_flag represents a level less than or equal to the specified level. profile_i idc is equal to 77, constraint_set0_fl
