Abstract

The paper discusses scalable video streaming traffic delivery over heterogeneous DiffServ/WLAN networks. A prototype architecture is proposed and further validated that explores the joint use of packet prioritization and scalable video coding (SVC) together with the appropriate mapping of 802.11e access categories to the DiffServ traffic classes. A complete set of simulation scenarios, involving four different video sequences using the scalable extension of H.264/MPEG-4 AVC, demonstrates the quality gains of both scalable video codingand prioritized packetization.
