多媒体现场集群调度系统的研究

Research on Trunked Dispatch Field System of Multi-Media

通过对目前通信市场和行业客户需求进行前瞻性调研和分析,研究了满足应急需求的多媒体集群调度系统,分析了多媒体集群调度系统的整体架构,对系统的功能模块进行划分,系统包括的功能模块有集群对讲、语音调度、移动视频调度、视频会议、统一通讯录、GIS功能和API模块。设计了系统的拓扑结构和多媒体数据传输与控制模式。最后对用户管理服务模块、多媒体语音调度模块、媒体移动视频调度模块、多分辨率、音视频会议、文件传输的技术参数进行说明。

In this paper,through the prospective research and analysis of the current communication market and industry customer needs,we have studied the trunked dispatch field system of multi-media. The overall architecture of the multimedia cluster scheduling system is analyzed,and the functional modules of the system are divided. The function modules of the system include cluster talkback,voice scheduling,mobile video scheduling,video conference,unified address book,GIS function and API module. The topology of the system,the transmission and control mode of multimedia data are designed. Finally,the technical parameters of user management module,multimedia voice scheduling module,media mobile video scheduling module,multi-resolution,audio and video conference,and file transfer are explained.
