Scalable video streaming over a wireless link with quality of service (QoS) is a very challenging task due to the time-varying characteristics of the wireless channel and limited battery resource in handheld devices. This paper proposes an end-to-end network-adaptive architecture for video streaming over 3G wireless networks. The proposed architecture not only dynamically estimates the varying network status on the fly, but also simultaneously performs application-level error control and transmission-level power control to protect against the random and fading error occurring across the 3G network. Distortion/power-minimized rate allocation is presented to achieve the minimum end-to-end distortion or minimum total power consumption based on the user's requirement. Simulation results demonstrate the effectiveness of our proposed scheme
