MVC scalable nesting SEI message and associated with an operation point for which the greatest VOIdx in the associated bitstream subset is equal to the particular value of VOIdx, the first of these buffering period SEI messages, in decoding order, is the activating view buffering period SEI message for the particular value of VOIdx. Otherwise, if the access unit contains a buffering period SEI message not included in an MVC scalable nesting SEI message, this buffering period SEI message is the activating view buffering period SEI message for the particular value of VOIdx equal to VOIdxMin. Otherwise, the access unit does not contain an activating buffering period SEI message for the particular value of VOIdx. When a sequence parameter set RBSP (nal_unit_type is equal to 7) with a particular value of parameter id is not already the active view MVC sequence parameter set RBSP for VOIdx equal to VOIdxMin and VOIdxMax is greater than VOIdxMin and it is referred to by activation of a picture parameter set RBSP (using that value of seq_parameter_set_id) and the picture parameter set RBSP is activated by a coded slice NAL unit with unit equal to 1 or 5 (the picture parameter set RBSP becomes the active view picture parameter set RBSP for VOIdx equal to VOIdxMin), it is activated for view components with VOIdx equal to VOIdxMin. This sequence parameter set RBSP is called the active view MVC sequence parameter set RBSP for VOIdx equal to VOIdxMin until it is deactivated when another MVC sequence parameter set RBSP becomes the active view MVC sequence parameter set RBSP for VOIdx equal to VOIdxMin or when decoding an access unit with VOIdxMax equal to VOIdxMin, whichever is earlier. A sequence parameter set RBSP, with that particular value of seq_parameter_set_id, shall be available to the decoding process prior to its activation. When a sequence parameter set RBSP (nal_unit_type is equal to 7) with a particular value of seq parameter_set is not already the active view MVC sequence parameter set RBSP for VOIdx equal to VOI
