ag is equal to 1, and the combination of level ide and constraint set3 fla represents a level less than or equal to the specified level. profile_ idc is equal to 77, constraint_set4_flag is equal to 1, and the combination of level_idc and constraint_set3_flag represents a level less than or equal to the specified level. Rec. ITU-T H.264 (01/2012) profile idc is equal to 88, constraint_setl_flag is equal to 1, constraint_set4_flag is equal to 1, and the combination of level_ide and constraint_set3_flagrepresents a level less than or equal to the specified level. profile_idc is equal to 100, constraint_set4_flag is equal to 1, and level id represents a level less than or equal to the specified level. A.2.4.2 Constrained High profile Bitstreams conforming to the Constrained High profile shall obey all constraints specified in clause A.2.4.1 for the Progressive High profile, and shall additionally obey the constraint that B slice types shall not be present. Conformance of a bitstream to the Constrained High profile is indicated by profile_idc being equal to 100 with both constraint set and constraint_set5_flag beingequal to 1. Decoders conforming to the Constrained 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_set1_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 idc is equal to 77, constraint_set0_flag is equal to 1, and the combination of level idc and constraint_set3_flagrepresents a level less than or equal to the specified level. profile_idc is equal to 77, constraint_set4_flag is equal to 1, constraint_set5_flag is equal to 1, and level_idc represents a level less than or equal to the specified level. profile_ is equal to 88, constraint setl is equal to 1, constraint_set4_flag is equal to 1, constraint_set5_flag is equal to 1, and the combination of
