| Abstract: | To realize the stable video feedback in the satellite self-servicing telerobotics system,a scheme based on scalable bit rate control is proposed.Delamination stream with different bit rates is selected according to the bandwidth detected in real time.Therefore,the scheme is very suitable for web video transmitting service since it is adaptive to various bandwidth networks.The experimental results demonstrate that stable and smoothing video streams can be obtained by teleoperator even in various bandwidth conditions.Furthermore,the performance of visual telepresence is highly improved. |
