随着广电设备形式日益IT化,广播电视信息数字化、网络化已基本实现,数字和高清制播能力大大提升。然而在我国西部经济欠发达地区、设备配置依然很低,很多县市级电视台全台网的建设未能完全按照总局《电视台数字化网络化建设白皮书》的要求搭建全台网络,多数县级市级电视台制播网效率低、安全漏洞较多,较大影响了工作效率,特别是新闻制作网络化,关键是服务器数据吞吐能力、系统抵御病毒能力、素材安全等多方面问题。本文就新技术条件下县市级电视台全台网络的升级改造展开分析和研究。 With the increasingly IT-based forms of radio and television equipment, digital radio and television information, networking has been basically achieved, digital and HD broadcast capacity greatly enhanced. However, the equipment allocation in the economically underdeveloped western areas of our country is still very low. Many county-level TV stations in Taiwan have failed to build the entire Taiwan network in accordance with the requirements of the “White Paper on Digital Network Construction of TV stations” in many counties and cities. Most county- Television broadcasting system low efficiency, more security loopholes, a greater impact on the work efficiency, especially the news production network, the key is the server data throughput capacity, the system resists the virus ability, material safety and many other issues. This article analyzes and researches upgrading and rebuilding of the whole station network of the county-level television station under the new technology condition.
