【摘要】：新时期网络媒体在社会生活中已经得到广泛应用,广播电视作为人们平时娱乐的一项重要选择其系统设计和运行需要与时俱进,不断完善,实现数字化、网络化。近年来电视台全台网收录系统逐渐在社会中得到运用,因为该系统能实现自动化、数字化和网络化,能为用户群体提供高效的工作效率和减少资金成本,因此,逐渐占领了社会市场[1]。电视台全台网建设主要是以视频和音频为主体的网络化、数字化、现代化平台。系统能实现素材采集、制作、存储、播出、共享等特点,能够对光纤网络、有线电视等多种渠道来源的视音频数据进行采集、存储,完成收录任务[2]。从而实现最精细化的管理、最优化的生产方式和最有效的资源整合。当前市场运用的系统虽然具备基本功能,但随着经济社会的发展,已经不能满足电视台全台网系统快速发展的要求。本文研究的全台网收录系统通过对模块化的设计与分析,能够改善系统的稳定性、全面性、高效性和安全性[3]。系统在设计构想中实行预分配的构想,通过使采集的模块设计能够独立自主实现单个系统,来保障系统的采集核心模块能够正常的运行。即使在网络运行出现异常的情况下,系统还能够正常运行,能够避免电视台在实际运行过程中发生事故,减少没有必要的损失。同时,该系统通过对总控和独立各个客户端的异步非阻塞的通信方式来实现系统的实时性交互。通过主体设备任务、主体设备总控、先本地后网络和双读双写的机制来为系统使用提供安全性能的保障[4]。即使在无人值守的情况下出现异常,系统也能自动重启并恢复正常。即使在与外部各系统互联互通或者与第三方融合,也可以显示出他的可扩展性和开放性。本文介绍了课题的研究背景,对全台网系统的性能设计、需求分析、整体实现和测试进行了小结。对电视台全台网收录系统的各个具体模块设计与实现构建进行了详细的论述,并通过一些方式对该系统进行了相应的实现测试。该系统安全性高、实时性强,能与外部系统互联互通,解决许多现实问题,提高了电视台的工作效率,能结合实际满足当前的发展市场需求。随着广电行业的发展与进步,电视台全台网收录系统的发展趋势将势不可挡,也将在整个行业中广泛运用起来。
[Abstract]:Network media has been widely used in social life in the new period. As an important choice for people's entertainment, radio and television system design and operation need to keep pace with the times, constantly improve and realize digitization. Network. In recent years, the TV network recording system has been gradually used in society, because it can achieve automation, digitization and networking, can provide efficient work efficiency for user groups and reduce the cost of funds, therefore, Gradually occupied the social market [1]. The construction of television station network is mainly based on video and audio as the main network, digital, modern platform. The system can achieve material collection, production, storage, broadcast, sharing and other characteristics. Can collect, store and complete the task of collecting and storing the video and audio data from many sources, such as optical fiber network, cable TV and so on. Optimization of production methods and most effective integration of resources. Although the systems currently used in the market have basic functions, with the development of the economy and society, The whole network collection system studied in this paper can improve the stability and comprehensiveness of the system through the design and analysis of modularization. High efficiency and security [3]. The system implements the preallocation concept in the design concept, and realizes a single system independently by making the module design of the collection independent. To ensure that the collection core module of the system can run normally. Even if the network operation is abnormal, the system can still operate normally, and can avoid accidents in the actual operation of the television station. At the same time, the system realizes real-time interaction by means of asynchronous non-blocking communication between master control and individual clients. The mechanism of first local network and double read and write to provide security performance for system use [4]. Even if there is an exception in unattended situations, The system can also automatically restart and return to normal. Even in connection with external systems or integration with third parties, it can also show its expansibility and openness. The performance design, requirement analysis, overall implementation and test of the whole network system are summarized. The design and implementation of each specific module of the TV station network collection system are discussed in detail. The system has the advantages of high security, high real-time, interworking with external system, solving many practical problems, and improving the working efficiency of TV station. With the development and progress of the radio and television industry, the development trend of the TV network collection system will be irresistible, and will be widely used in the whole industry.
