备注

提出地震会商中会议发起人—参与者的应用模式,研究了会商期间通过在广播端实时广播操作消息、运用网络实时推送技术,使各异地参与的信息节点会商资料内容一致,同时接收端实时接收并执行操作消息,从而同步显示广播计算机的操作画面,最终达到模拟广播视音频效果。该方式既克服了普通网络视频会议图像对网络带宽要求高的缺点,又增强了会商会议在线动态数据分析的真实性与及时交互性,亦突破了传统会商会议只能局限在同一会场的限制。本系统经试点单位的应用取得了良好效果。

We propose the application model of sponsors-participant in earthquake consultation meeting and study the real-time broadcast operation messages technology in the broadcasting side and real-time pushing technology by network to make the consultation data same of different information nodes in different place. At the same time,the technology makes the receiving side receive and execute the operation message in real time,and synchronously display the operation screen of broadcast computer to reach the effect of analog broadcast video and audio eventually. This method not only overcomes the shortcoming of high requirements for network bandwidth of general network video conferencing image,but also enhances the authenticity and timely interaction of analysis on the online dynamic data in earthquake consultation meeting,and breaks the restriction of traditional consultation meeting which must be in the same venue. The system has achieved good results in the initial application of experiment unit.
