高清视频会议系统在辽宁气象服务中的应用

基于辽宁气象宽带广域网络，建立辽宁省气象部门高清视频会议系统.该系统遵循先进性、标准化、安全可靠、灵活扩展、易操作的原则，以省级控制中心为节点，具备高清视频会议收听收看、转发及录制的功能，在辽宁气象服务体系中得到广泛应用.本文对辽宁气象高清视频会议系统架构、系统组成以及实现该系统视音频功能的关键技术进行了分析，同时结合业务发展需要，新建移动终端视频会议接入系统，最后以我省高清视频会议系统的音频故障为例，创建音频故障树，运用故障树分析法对该系统音频的稳定性进行了定量和定性分析.

Application of HD Video Conference System in Liaoning Meteorological Service

Based on Liaoning meteorological broadband wide area network, the HD video conference system of Liaoning Meteorological Department was established. The system follows the principle of advanced, standardized, safe and reliable, flexible expansion and easy operation, takes the provincial control center as the node, and has the function of high-definition video conference listening, watching, forwarding, and recording, which has been widely used in Liaoning meteorological service system. In this study, the Liaoning meteorological high-definition video conferencing system architecture, system composition, and key technologies to realize the system audio function are analyzed. At the same time, combined with the needs of business development, the new access system of mobile terminal video conference was set up. Finally, taking the audio fault of Liaoning Province HD video conference system as an example, the audio fault tree is established, and the audio stability of the system is quantitatively and qualitatively analyzed by using the fault tree analysis method.
