Secure scalable video streaming for wireless networks
Susie J. Wee, J.G. Apostolopoulos · 2005
We present a wireless video streaming system that securely and efficiently streams video to heterogeneous clients over timevarying communication links. Clients may differ in their display, power, communication, and computational capabilities and wireless channels may have time-varying bandwidths and quality levels that depend on channel usage and channel conditions. End-to-end system efficiency is achieved by placing transcoders at intermediate network nodes; these transcoders can easily adapt the video stream for particular client capabilities and network conditions.
