随着广电技术的蓬勃发展,电视信号开始从模拟信号向数字信号过渡,与此同时计算机软硬件技术也在高速发展,使得视音频信号可以以数据的方式存储于以RAID技术为依托的硬盘存储设备中,随着千兆网络的技术的日益完善和普及,可将制作网与播出网通过交换机互联形成一个统一的小型局域网。网络中所采用的网络设备均遵守OSI参考模型,基于TCP/IP协议集,通过千兆以太网实现制作网素材与播出网素材资源的共享、传输和处理。基于此,就乌鲁木齐电视台数字移动电视制播一体机房使用中的千兆以太网络维护发表一些个人体会。
With the vigorous development of radio and television technology, television signals began to transition from analog signals to digital signals. Meanwhile, computer hardware and software technologies are also developing rapidly, enabling video and audio signals to be stored in a data-based manner on hard disk storage In the equipment, as the technology of the gigabit network is perfected and popularized, the production network and the broadcasting network can be interconnected through a switch to form a unified small local area network. Network equipment used in the network comply with the OSI reference model, based on the TCP / IP protocol set, through the Gigabit Ethernet production network material and broadcast network material resources sharing, transmission and processing. Based on this, on the Urumqi TV digital mobile TV broadcast room using Gigabit Ethernet network to maintain some personal experience.
