 H.8.2.1 is equal to "no reference picture", ef_pic_list_modification_flag_l1 shall be equal to 1 and modification_of_pic_nums_idcs shall not be equal to 3 until RefPicList1[num_ref_idx_ll_active_minus1]in the modified list produced as specified in clause H.8.2.2 is not equal to "no reference picture". H.7.4.3.1.1 Reference picture list MVC modification semantics semantics specified in clause 7.4.3.1 apply with the following modified semantics of Rec. ITU-T H.264 (01/2012) modification_of_pic_nums_idc. In addition, the semantics of abs_diff_view_idx_minus1 specified below apply. modification_of_pic_nums_ide together with abs_diff_pic_num_minus1, long_term_pic_num, abs_diff_view _idx minus1 specifies which of the reference pictures or inter-view only reference components are re-mapped. The values of modification of pic_nums_idc are specified in Table H-1. The value of the first modification_of_pic_nums_ide that follows immediately after ref_pic_list_modification_flag_10 ref_pic_list_modification_flag_11 shall not be equal to 3. Table H-1 - modification_of_pic_nums_ide operations for modification of reference picture lists modification_of_pic_nums_id Modification specified abs diff pic num minus1 is present and corresponds to a difference to subtract from a picture number prediction value abs diff pic num minus1 is present and corresponds to a difference to add to a picture number prediction value long term pic num is present and specifies the long-term picture number for a reference picture End loop for modification of the initial reference picture list abs diff view idx minus1 is present and corresponds to a difference to subtract from a prediction value of the reference view index abs diff view idx minus1 is present and corresponds to a difference to add to prediction value of the reference view index abs_diff_view_idx_minus1 plus 1 specifies the absolute difference between the reference view index to put to the current index in the reference picture list and the prediction value of the reference view index.
