retation of SEI messages that apply to the entire access unit or the view component with VOIdx equal to VOIdxMax, the values of the parameters of the active picture parameter set and the active MVC sequence parameter set for the same access unit shall be considered in effect unless otherwise specified in the SEI message semantics. For interpretation of SEI messages that apply to view components with a particular value of VOIdx less than VOIdxMax, the values of the parameters of the active view picture parameter set and the active view MVC sequence parameter set for the particular value of VOIdx for the same access unit shall be considered in effect unless otherwise specified in the SEI message semantics. Rec. ITU-T H.264 (01/2012) H.7.4.1.2.2 Order of access units and association to coded video sequences The specification of clause 7.4.1.2.2 applies with the following modifications. The first access unit of the bitstream shall only contain coded slice NAL units with nal_unit_type equal to 5 or non_idr_flag equal to 0. The order of NAL units and coded pictures and their association to access units is described in clause H.7.4.1.2.3. H.7.4.1.2.3 Order of NAL units and coded pictures and association to access units The specification of clause 7.4.1.2.3 applies with the following modifications. NOTE - Some bitstreams that conform to one or more profiles specified in this annex do not conform to any profile specified in Annex A (prior to operation of the base view extraction process specified in clause H.8.5.4). As specified in clauses 7.4.1 and 7.4.1.2.3, for the profiles specified in Annex A, NAL units with nal unit equal to 20 are classified as non-VCL NAL units that must be preceded within each access unit by at least one NAL unit with nal_unit_type in the range of 1 to 5, inclusive. For this reason, any bitstream that conforms to one or more profiles specified in this annex does not conform to any profile specified in Annex A when it contains any of the following: any access unit that does not contain any NAL uni
