【摘要】：随着科技的迅速发展,信息的可视化控制管理的需求日趋增加。用于多级调度的视频矩阵在选择输入信号源和输出通道方面起着极其重要的作用。但目前大多数的电视台所使用的视频矩阵存在以下不足：各矩阵系统相互独立；缺少信息、资源的共享；矩阵的控制单一；控制界面按键密集、容易发生误操作等。为解决以上问题,本文以南宁电视台为研究应用平台,研究和开发了一个分布式集群视频矩阵调度系统。主要研究工作包括：首先提出了系统的整体设计方案,将矩阵的调度架构作为设计重点,根据系统功能需求,确定系统搭建模式,完成了系统所需的硬件接口配置。其次完成了系统的整体硬件改建及矩阵的架构、控制命令信息传输、视音频数据的传输、接收与分配等部分的设计。然后在系统的软件实现上,采用Microsoft VC++6.0 SP6开发,完成了分布式集群视频矩阵系统的数据库管理模块、终端控制模块、视频矩阵控制服务模块、视频矩阵端口设置模块、权限管理模块、日志管理模块等模块的软件开发。最后以南宁电视台播出机房为研究应用对象,对其系统进行了部署调试。实验结果表明：该系统能在任意一个分布站点实现对矩阵上的任意视频信号的调度,还能快速、准确的获取需要的信号源,以及对矩阵的操作信息进行操作人员的验证,记录相关的操作信息。该系统的使用大大提高了录制、采集、监看节目时进行视频音频的调度的效率,减少了人力和财力的重复投入,有效降低了成本,是一种新型的、有效的分布式视频矩阵调度控制管理系统。
[Abstract]:With the rapid development of science and technology, the demand of information visual control management is increasing day by day. Video matrix for multilevel scheduling plays an important role in selecting input signal sources and output channels. However, the video matrix used by most TV stations has the following shortcomings: each matrix system is independent, the information is lacking, the resources are shared, the control matrix is single, and the control interface is dense and prone to misoperation. In order to solve the above problems, a distributed cluster video matrix scheduling system based on Nanning TV station is studied and developed in this paper. The main research work is as follows: firstly, the overall design scheme of the system is proposed. The scheduling architecture of the matrix is taken as the key point of the design. According to the system functional requirements, the system construction mode is determined, and the hardware interface configuration required by the system is completed. Secondly, the whole hardware reconstruction and matrix architecture of the system are completed, the control command information transmission, the transmission of video and audio data, the receiving and distribution of video and audio data, and so on are designed. Then, in the software realization of the system, the database management module, the terminal control module, the video matrix control service module, the video matrix port setting module of the distributed cluster video matrix system are developed by using Microsoft VC 6.0 SP6. Privilege management module, log management module and other modules of software development. Finally, the system is deployed and debugged with Nanning TV station broadcasting computer room as the object of study and application. The experimental results show that the system can schedule any video signal on the matrix at any distributed station, obtain the needed signal source quickly and accurately, and verify the operation information of the matrix. Record relevant operational information. The use of the system greatly improves the efficiency of video and audio scheduling when recording, collecting and watching programs, reduces the repeated investment of human and financial resources, effectively reduces the cost, and is a new type. An effective distributed video matrix scheduling management system.
