nd A.2.1.1 shall be obeyed. Rec. ITU-T H.264 (01/2012) ii) Sequence parameter sets should have profile_idc equal to 66. Sequence parameter sets may have profile idc equal to 77 or 88. Sequence parameter sets shall not have profile_idc equal to a value other than 66, 77, or 88. iii) Sequence parameter sets shall have constraint_set0_flag, constraint_setl_flag, and constraint_set2_flag equal to 1. NOTE 1 - The above constraint implies that picture parameter sets must have num_slice_groups_minus1 equal to 0 and redundant_pic_cnt_present_flag equal to 0 and that arbitrary slice order is not allowed. NOTE 2 - In addition to the base layer constraints specified above in items i) through iii), the value of the syntax element constrained_intra_pred_flag for picture parameter sets of the base layer stream is constrained as specified below in item m). b) A list of integer values specifying layer representation identifiers is derived by invoking the process specified in clause G.8.1.1 with the output being the list dqIdList. The SVC sequence parameter sets that are referred to by coded slice NAL units with DQId greater than 0 and DQId in the list dqIdList shall have profile_idc equal to 83 and both constraint_set1_flag and constraint_set5_flag equal to 1 or (profile_idc equal to 86 and both constraint_set0_flag and constraint_set5_flag equal to 1). c) Only I, P, EI, and EP slices shall be present. d) SVC sequence parameter sets shall have chroma_format_idc equal to 1. e) SVC sequence parameter sets shall have bit_depth_luma_minus8 equal 0. f) SVC sequence parameter sets shall have bit_depth_chroma_minus8 equal to 0. SVC sequence parameter sets shall have separate_colour_plane_flag equal to 0. h) SVC sequence parameter sets shall have qpprime_y_zero_transform_bypass_flagequal to 0. i) SVC sequence parameter sets shall have frame_mbs_only_flag equal to 1. Picture parameter sets shall have redundant_pic_cnt_present_flag equal to 0. k) Picture parameter sets shall have num_slice_groups_minus1 equal to 0. 1) Arbitrary slice orde
