Optimal Frame Rate Allocation for Unicast and Multicast Wireless Video Communication
In this paper, the authors consider a paradigm for sum perceptual quality maximization in the context of unicast and multicast video transmission to heterogeneous multimedia wireless clients. The multimedia server is constrained by the processing overheads required for tasks such as video encoding, bit-stream extraction, packetisation, etc. They demonstrate that the above problem of perceptual quality maximization is well represented by a constrained optimization framework. Further, this model can be readily extended to include QoS considerations in multicast transmission. Based on the system model, they present a closed form solution for frame rate allocation and a comprehensive algorithm for sum quality maximization.
