摘　　要：为实现卫星自维护遥操作系统中稳定可靠的视频反馈目标,提出一种基于分层码率控制的视频传输策略.利用实时探测到的带宽选择不同码率的视频流分层,使得视频传输对于不同的网络带宽具有自适应性.试验结果表明,该策略能够在波动带宽下给予遥操作者稳定流畅的视频反馈,有效地提高了遥操作系统的视觉临场感性能.To realize the stable video feedback in the satellite self-servicing telerobotics system, based on scalable bit rate control is proposed. Delamination stream with different bit rates is selected a scheme 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.
