With the advances in wireless technology and explosive growth of mobile devices and wireless networks, mobile TV is becoming a popular application. The main technical challenge to wireless video broadcast is to provide the best quality of service possible under the radio resource constraints. In this paper we propose an application layer middleware solution that utilizes the scalability in video coding with rateless erasure correction codes to achieve a balance in the quality of service (QoS) and radio resource efficiency. Simulation results demonstrate the effectiveness of the solution.
