s for all values of seq_parameter_set_id. The content of the sequence parameter set with a particular value of seq_parameter_set_id is overwritten when a new sequence parameter set NAL unit with the same value of seq parameter_set_id is received, and the content of the subset sequence parameter set with a particular value of is overwritten when new subset sequence parameter set NAL unit with the same value of seq_parameter_set_id is received When present, a sequence parameter set extension RBSP includes parameters having a similar function to those of a sequence parameter set RBSP. For purposes of establishing constraints on the syntax elements of the sequence parameter set extension RBSP and for purposes of determining activation of a sequence parameter set extension RBSP, the sequence parameter set extension RBSP shall be considered part of the preceding sequence parameter set RBSP with the same value of __parameter_set_id. When a sequence parameter set RBSP is present that is not followed by a sequence parameter set extension RBSP with the same value of eq_parameter_set_id prior to the activation of the sequence parameter set RBSP, the sequence parameter set extension RBSP and its syntax elements shall be considered not present for the active MVC sequence parameter set RBSP. The contents of sequence parameter set extension RBSPs only apply when the base view, which conforms to one or more of the profiles specified in Annex A, of a coded video sequence conforming to one or more profiles specified in Annex H is decoded. Subset sequence parameter set RBSPs shall not be followed by a sequence parameter set extension RBSP. NOTE 6 - Sequence parameter sets extension RBSPs are not considered to be part of a subset sequence parameter set RBSP and subset sequence parameter set RBSPs must not be followed by a sequence parameter set extension RBSP. For view components with VOIdx equal to VOIdxMax, all constraints that are expressed on the relationship between the values of the syntax elements (and the values of variables
