A Rate Control Scheme for Adaptive Video Streaming Over the Internet

—In this paper, we propose a new streaming protocol, namely Dynamic Video Rate Control (DVRC), which enables adaptive video delivery over the Internet. DVRC operates on top of UDP providing a congestion-controlled flow of unreliable datagrams. The proposed rate control scheme is able to interact with new and existing video streaming applications which are capable of adjusting their rate based on congestion feedback. DVRC attempts to optimize the performance of video delivery with concern to friendliness with interfering traffic. Exploring DVRC’s potential through extensive simulations, we identify notable gains in terms of bandwidth utilization and smooth video delivery. Furthermore, our results indicate that the protocol allocates a well-balanced amount of network resources maintaining friendliness with coexisting flows.
