Rate Control and Stream Adaptation for Scalable Video Streaming Over Multiple Access Networks
In a multihomed video streaming system, a video sequence is simultaneously transmitted over multiple access networks to a client. In this paper, the authors formulate the rate control and stream adaptation problems into a unified optimization problem, which determines the sending rates of individual networks, selects which video packets to transmit, and assigns each packet to an access network. The authors propose two heuristic algorithms with a trade-off between optimality and computational complexity. One of the proposed algorithms runs faster, while the other one results in better video quality.
