ual to 1, the coded video sequence must obey the constraints of all of the indicated subclauses of clause A.2. When profile idc is equal to 44, 100, 110, 122, or 244, the values of constraint_set0_flag, constraint_setl_flag, and constraint_set2_flag must all be equal to 0. constraint set3_fl: is specified as follows: If profile idc is equal to 66, 77, or 88 and level_ide is equal to 11, constraint equal to 1 indicates that the coded video sequence obeys all constraints specified in Annex A for level 1b and constraint_set3_flag equal to 0 indicates that the coded video sequence obeys all constraints specified in Annex A for level 1.1. Otherwise, if profile_idc is equal to 100 or 110, constraint_set3_flag equal to 1 indicates that the coded video sequence obeys all constraints specified in Annex A for the High 10 Intra profile, and constraint_set3_flag equal to 0 indicates that the coded video sequence may or may not obey these corresponding constraints. Otherwise, if profile_idc is equal to 122, constraint_set3_flag equal to 1 indicates that the coded video sequence obeys all constraints specified in Annex A for the High 4:2:2 Intra profile, and constraint_set3_flag equal to 0 indicates that the coded video sequence may or may not obey these corresponding constraints. Otherwise, if profile_idc is equal to 44, constraint_set3_flag shall be equal to 1. When profile_idc is equal to 44, the value of 0 for constraint_set3_flag is forbidden. Otherwise, if profile_idc is equal to 244, constraint_set3_flag equal to 1 indicates that the coded video sequence obeys all constraints specified in Annex A for the High 4:4:4 Intra profile, and constraint_set3_flag equal to 0 indicates that the coded video sequence may or may not obey these corresponding constraints. Otherwise (profile_ido is equal to 66, 77, or 88 and level idc is not equal to 11), the value of 1 for constraint_set3_fla is reserved for future use by ITU-T | ISO/IEC. constraint_set3_flag shall be equal to 0 for coded video sequences with profile_i equal to 66, 77,
