基于无参考质量评估的会议电视运维系统研究

Research on Video Conference Maintenance System Based on No-reference Video Quality Assessment Method

会议电视系统运维是保证系统稳定高效运行的重要工作,而用户希望通过自动化的方式完成日常运维工作。为此,文中首先分析了会议电视系统及音视频质量评估方法的现状,然后在会议电视智能化运维系统建设目标和定位的基础之上,从系统总体架构出发,归纳运维业务需求,建立系统应用架构和数据分类,并提出系统逻辑架构和逻辑分层的技术实现方式,最后对系统安全、应用集成的设计方法进行分析。文中详细阐述了基于无参考音视频质量评估方法的会议电视智能化运维系统的设计,实际应用表明该系统实现了会议自动巡检及故障排查,建立了完善的会议质量评估方法,在流程上实现了会议的闭环,可以满足会议电视系统运维工作自动化、智能化的需求。

The maintenance of the video conference system is an important activity to ensure its stable and efficient operation for system.In order to meet the user needs of automatic maintenance,it analyzes firstly the current situation of the video conference system and the video quality assessment in this paper. Then,based on the project orientation and construction objective,starting the overall architecture,the maintenance business requirements is generalized,the system application architecture and data classification is established,and its logic architecture and the logic layered technology for system is presented. Finally,the analysis is conducted in design method of system security and application integration. The design of the video conference maintenance system using no-reference video quality assessment method is described in detail. In the application,the system realizes the automatic inspection and failure detection,and establishes complete conference quality assessment method to implement closed loop in process,which can meet the requirements for the automatic and intelligent maintenance of the video conference system.
