摘　　要：本文介绍了一种运用于无线实时视频监控系统的基于反馈机制的带宽自适应策略,通过接收端统计视频数据包的接收情况,并反馈至发送端,调整发送端的分包及数据传输策略,获得流畅、低延迟的视频传输性能。并且在基于CDMA1X技术的移动通信网络的视频监控系统上应用并验证其性能。This paper presents a design of a feedback mechanism for channel-adaptive wireless real-time video surveillance system. A feedback mechanism including the statistic method used at the receiver end and the accordingly adjustment made at the transmitter end is introduced. Through an experiment comparing using this mechanism and not, we showed that the feedback mechanism can offer a better performance with both continuous and the quality of video transmission.
