【摘要】：隨著科技的迅速發(fā)展,信息的可視化控制管理的需求日趨增加。用于多級(jí)調(diào)度的視頻矩陣在選擇輸入信號(hào)源和輸出通道方面起著極其重要的作用。但目前大多數(shù)的電視臺(tái)所使用的視頻矩陣存在以下不足：各矩陣系統(tǒng)相互獨(dú)立；缺少信息、資源的共享；矩陣的控制單一；控制界面按鍵密集、容易發(fā)生誤操作等。為解決以上問題,本文以南寧電視臺(tái)為研究應(yīng)用平臺(tái),研究和開發(fā)了一個(gè)分布式集群視頻矩陣調(diào)度系統(tǒng)。主要研究工作包括：首先提出了系統(tǒng)的整體設(shè)計(jì)方案,將矩陣的調(diào)度架構(gòu)作為設(shè)計(jì)重點(diǎn),根據(jù)系統(tǒng)功能需求,確定系統(tǒng)搭建模式,完成了系統(tǒng)所需的硬件接口配置。其次完成了系統(tǒng)的整體硬件改建及矩陣的架構(gòu)、控制命令信息傳輸、視音頻數(shù)據(jù)的傳輸、接收與分配等部分的設(shè)計(jì)。然后在系統(tǒng)的軟件實(shí)現(xiàn)上,采用Microsoft VC++6.0 SP6開發(fā),完成了分布式集群視頻矩陣系統(tǒng)的數(shù)據(jù)庫管理模塊、終端控制模塊、視頻矩陣控制服務(wù)模塊、視頻矩陣端口設(shè)置模塊、權(quán)限管理模塊、日志管理模塊等模塊的軟件開發(fā)。最后以南寧電視臺(tái)播出機(jī)房為研究應(yīng)用對(duì)象,對(duì)其系統(tǒng)進(jìn)行了部署調(diào)試。實(shí)驗(yàn)結(jié)果表明：該系統(tǒng)能在任意一個(gè)分布站點(diǎn)實(shí)現(xiàn)對(duì)矩陣上的任意視頻信號(hào)的調(diào)度,還能快速、準(zhǔn)確的獲取需要的信號(hào)源,以及對(duì)矩陣的操作信息進(jìn)行操作人員的驗(yàn)證,記錄相關(guān)的操作信息。該系統(tǒng)的使用大大提高了錄制、采集、監(jiān)看節(jié)目時(shí)進(jìn)行視頻音頻的調(diào)度的效率,減少了人力和財(cái)力的重復(fù)投入,有效降低了成本,是一種新型的、有效的分布式視頻矩陣調(diào)度控制管理系統(tǒng)。
[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.
