dxMin and VOIdxMax is greater than VOIdxMin and it is referred to by an activating view buffering period SEI message (using that value of eq_parameter_set_id) that is not included in an MVC scalable nesting SEI message, the sequence parameter set RBSP 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. 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. Rec. ITU-T H.264 (01/2012) When a subset sequence parameter set RBSP (nal_unit_type is equal to 15) with a particular value of seq_parameter_set id is not already the active view MVC sequence parameter set RBSP for a particular value of VOIdx less than VOIdxMax 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 MVC extension NAL unit (nal_unit_type equal to 20) with the particular value of VOIdx (the picture parameter set RBSP becomes the active view picture parameter set RBSP for the particular value of VOIdx), it is activated for view components with the particular value of VOIdx. This subset sequence parameter set RBSP is called the active view MVC sequence parameter set RBSP for the particular value of VOIdx until it is deactivated when another MVC sequence parameter set RBSP becomes the active view MVC sequence parameter set RBSP for the particular value of VOIdx or when decoding an access unit with VOIdxMax less than or equal to the particular value of VOIdx. A subset sequence parameter set RBSP, with that particular value of seq_parameter_set_id, shall be available to the decoding process prior t
