摘要： 在局域网多点视频监控系统中，当监控点和用户增加时视频数据在网络上的传输量会大大增加，将导致网络带宽严重不足，无法保证用户的QoS。该文针对此问题提出了基于多Agent的视频监控系统模型——MPMU（MultiPoint MultiUser），用IDL（Interface Definition Language）对模型进行了描述，并在此模型中实现了QoS协商、重协商和基于MPEG-I数据流的丢帧机制。实验结果表明，此模型可以满足多监控点和多用户的需求。

Abstract: In the LAN multipoint video monitor and control system,with the number of monitor and control point and user increasing the video quantity of transmission over network will augment greatly,which causes the lack of LAN bandwidth and the QoS of user can not be insured.To solve this problem,a video monitor and control system model based on Multi-agent——MPMU and its description with IDL are presented in this paper,in which QoS negotiation, renegotiation and frame-drop mechanism based on MPEG-I data stream are implemenfed . The result of experiments shows that the model can satisfy the demand of multipoint and multi-user.
