The paper discusses the end-to-end QoS provisioning for scalable video streaming traffic delivery
over heterogeneous IP/UMTS networks. A prototype architecture is proposed, and is further
validated, that explores the joint use of packet prioritization and scalable video coding (SVC)
together with the appropriate mapping of UMTS traffic classes to the DiffServ traffic classes. A
complete set of simulation scenarios, involving eight different video sequences and using two
different scalable encoders, demonstrates the quality gains of both scalable video coding and
prioritized packetization.
