Congestion control scheme for UHD video streaming over the Internet
Sung-Hee Lee, Hyunwoo Lee, Won Ryu · 2015
Advances in multimedia and network technology enables to stream UHD video over public Internet. However, previous congestion control schemes have several limitations to guarantee the quality of UHD video streaming. The sluggish behavior of congestion control scheme disturbs the rapid increase in video quality. Another problem is burst packet losses caused by overshooting of transmission rate. These burst packet losses degrade the quality of video. In this paper, we propose a congestion control scheme to improve the quality of UHD video streaming service. The proposed scheme quickly increases the video quality and reduces packet losses by using concave, convex, and linear function. Simulation results have shown that our scheme can improve the quality of UHD video streaming service.
