Mobile video transmission using scalable video coding

The Scalable Video Coding (SVC) standard as an extension of H.264/AVC\nallows efficient, standard-based temporal, spatial, and quality\nscalability of video bit streams. Scalability of a video bit stream\nallows for media bit rate as well as for device capability adaptation.\nMoreover, adaptation of the bit rate of a video signal is a desirable\nkey feature, if limitation in network resources, mostly characterized by\nthroughput variations, varying delay or transmission errors, need to be\nconsidered. Typically, in mobile networks the throughput, delay and\nerrors of a connection (link) depend on the current reception\nconditions, which are largely influenced by a number of physical\nfactors. In order to cope with the typically varying characteristics of\nmobile communication channels in unicast, multicast, or broadcast\nservices, different methods for increasing robustness and achieving\nquality of service are desirable. We will give an overview of SVC and\nits relation to mobile delivery methods. Furthermore, innovative use\ncases are introduced which apply SVC in mobile networks.
