t would conform to the specified constraints if it were activated by reference in an otherwise-conforming bitstream. During operation of the decoding process (see clause G.8), for layer representations with DQId equal to DQIdMax, the values of parameters of the active picture parameter set and the active SVC sequence parameter set shall be considered in effect. For layer representations with a particular value of DQId less than DQIdMax, the values of the parameters of the active layer picture parameter set and the active layer SVC sequence parameter set for the particular value of DQId shall considered in effect. For interpretation of SEI messages that apply to access units or dependency representations with dependency_id equal to DependencyIdMax or layer representation with DQId equal to DQIdMax, the values of the parameters of the active picture parameter set and the active SVC sequence parameter set for the access unit shall be considered in effect unless otherwise specified in the SEI message semantics. For interpretation of SEI messages that Rec. ITU-T H.264 (01/2012) apply to dependency representations with a particular value of dependency_id less than DependencyIdMax the values of the parameters of the active layer picture parameter set and the active layer SVC sequence parameter set for the layer representation with DQId equal to ( dependency of the access unit shall be considered in effect unless otherwise specified in the SEI message semantics. For interpretation of SEI messages that apply to layer representations with a particular value of DQId less than DQIdMax, the values of the parameters of the active layer picture parameter set and the active layer SVC sequence parameter set for the layer representation with the particular value of DQId of the access unit shall be considered in effect unless otherwise specified in the SEI message semantics. G.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
