When the coded video sequence conforms to one or more of the profiles specified in Annex H and the decoding process specified in Annex H is applied, the following is specified: (a) When an access unit contains one or more buffering period SEI messages that are included in MVC scalable nesting SEI messages, the buffering period SEI message that is associated with the operation point being decoded is the buffering period SEI message that initialises the HRD. Let hrdVId[ i be equal to sei_op_view_id[i] for all i in the range of 0 to num_view_components_op_minus1, inclusive, and let hrdTId be the value of sei _temporal_io that are associated with the MVC scalable nesting SEI message containing the buffering period SEI message that initialises the HRD. (b) The picture timing SEI messages that specify the removal timing of access units from the CPB and output timing from the DPB are the picture timing SEI messages that are included in MVC scalable nesting SEI messages associated with values of sei_op_view_id[i] equal to hrdVId[ for all i in the range of 0 to num_view_components_op_minus1 inclusive, and sei_temporal_ id equal to hrdTId. (c) The HRD parameter sets that are used for conformance checking are the HRD parameter sets, included in the MVC video usability information extension of the active MVC sequence parameter set, that are associated with values sofvui_mvc_view_id[i][j] for all j in the range of 0 to vui_mvc_num_target_output_views_minus1[i], inclusive, equal
