parameter set RBSP (using that value of q_parameter_set_id) and the picture parameter set RBSP is activated by a coded slice NAL unit with to 1 or 5 (the picture parameter set RBSP becomes the active picture parameter set RBSP and VOIdxMax is equal to VOIdxMin) and the access unit does not contain an activating buffering period SEI message, it is activated. This sequence parameter set RBSP is called the active MVC sequence parameter set RBSP until it is deactivated when another MVC sequence parameter set RBSP becomes the active MVC sequence parameter set RBSP. 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_typ is equal to 7) with a particular value of seq parameter id is not already the active MVC sequence parameter set RBSP and it is referred to by an activating buffering period SEI message Rec. ITU-T H.264 (01/2012) (using that value of seq_parameter_set_id) that is not included in an MVC scalable nesting SEI message and VOIdxMax is equal to VOIdxMin, it is activated. This sequence parameter set RBSP is called the active MVC sequence parameter set RBSP until it is deactivated when another MVC sequence parameter set RBSP becomes the active MVC sequence parameter set RBSP. A sequence parameter set RBSP, with that particular value of seq_parameter_set_id shall available to the decoding process prior to its activation. 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 MVC sequence parameter set RBSP and it is referred to by activation of a picture parameter set RBSP (using that value of eq_parameter_set_id) and the picture parameter set RBSP is activated by a coded slice MVC extension NAL unit (nal_unit_type is equal to 20) with VOIdx equal to VOIdxMax (the picture parameter set RBSP becomes the active picture parameter set RBSP) and the access unit does not contain an acti
