Abstract :
With an empirically-derived complexity-rate-distortion model of a complexity scalable video encoder, we study the distributed optimization of several encoders sharing a wireless network, using the PSNR of the decoded video as the utility function. We will demonstrate how universal frequency reuse and source rate control can help the system degrade gracefully with increasing users, show the value of a simple pricing mechanism on transmission power in improving performance and study the effect of power allocation between transmitter and source encoder.
