Stochastic Rate Control for Scalable VBR Video Streaming Over Wireless Networks

Video streaming over wireless links is a challenging problem due to both the unreliable, time-varying nature of the wireless channel and the stringent delivery requirements of media traffic. Layered encoded video can be used to improve the system performance by adapting the sending rate for different video frame layers to the varying network and playout situations. This paper studies the adaptive control of sending rates for both the base layer and enhancement layer based on feedback information from the wireless receiver.
