The range of num_ref_idx_l1_active_minus] is constrained as specified in the semantics for num ref idx 10active minus1 in this clause with 10 and list 0 replaced by 11 and list 1, respectively. H.7.4.3.1 Reference picture list modification semantics The semantics specified in clause 7.4.3.1 apply with the following modifications. ref_pic_list_modification_flag_10 equal to 1 specifies that the syntax element modification of is present for specifying reference picture list 0. ref_pic_list_modification_flag_1 equal to 0 specifies that this syntax element is not present. When ref_pic_list_modification_flag_10 is equal to 1, the number of times that modification_of_pic_nums_idc is not equal to 3 following ref_pic_list_modification_flag_10 shall not exceed num_ref_idx_10_active_minus1+1 When RefPicList0[ num ref idx 10 active_minus1 ] in the initial reference picture list produced as specified in clause H.8.2.1 is equal to "no reference picture", ef_pic_list_modification_flag_10shall be equal to 1 and modification_of_pic_nums_idc shall not be equal to 3 until RefPicList0[num_ref_idx_10_active_minusl] in the modified list produced as specified in clause H.8.2.2 is not equal to "no reference picture". ref_pic_list_modification_flag_I equal to 1 specifies that the syntax element modification_of_pic_nums_idci is present for specifying reference picture list 1. ref_pic_list_modification_flag_11 equal to 0 specifies that this syntax element is not present. When ref_pic_list_modification_flag_ll is equal to 1, the number of times that modification_of_pic_nums_ido is not equal to 3 following ref_pic_list_modification_flag_l1 shall not exceed num_ref_idx_l1_active_minus1 + 1.
