(English Abstract)
Due to the development of handheld devices and communication technology, interests and demands for various forms of video streaming services have been increasing. Thus, the rate control schemes are studied to improve the quality of video streaming service. However, previous rate control schemes aware network status based on packet losses. These packet losses degrade the quality of video streaming. In this paper, we propose a delay trend-based rate control scheme to improve the quality of streaming by reducing packet losses. The proposed scheme reduces the packet losses by adjusting the transmission rate based on the network delay trend before a packet loss occurs. Through the simulation results, we prove that our scheme improves the quality of video streaming by causing less packet losses.
