On attempting live video streaming over wireless networks, an appropriate congestion control which provides robustness against wireless losses is imperative. This is because the congestion controls designed for wired networks consider all the packet losses as congestion indication and reduce their sending rate unreasonably. VTP (Video Transport Protocol) is a congestion control designed for wireless video transmission by using AR (Achieved Rate) which is the actual receiving rate. In this paper, we investigate that AR is not measured correctly when the encoding delay is larger than the target frame rate. And we propose another method correcting AR measurement with the cooperation between encoder and congestion control. Moreover, we confirmed the effectiveness of our proposal in actual wireless environment. |
