Abstract

The scalable video coding (SVC) technique employs layered scalability to accommodate device capabilities and transmission conditions to meet QoS requirements for streaming video services in wireless access networks. However, the SVC streaming video still suI ff Pers perceivable service interruption during handover in wireless access networks. Much of the previous res earch focused on the strategies of shortening handover latency to mitigate service disturbance. Nevertheless, latency shortening cannot fully eliminate service gaps and service interruptions. This paper utilizes the layered scalability of SVC video streams and proposes an adaptive buffer filling approach for seamless video streaming services. The adaptive buffer filling approach can select appro priate SVC coded layers to allow SVC video streams to prepare for crossing service gaps in an active manner. Furthermore, this paper uses the proposed strategy in the context of mobile WiMAX networks. Simulated results show that the proposed seamless service strategy effectively decreases the probability of service interruption in SVC streaming video services.
