摘要
当前,调频广播和电视发射技术已全面数字化,地面数字电视正向高清化、双向信息化发展,高山台站整体系统架构需要紧跟技术发展的脚步,超前预测系统面临的技术变革,适应形势的发展。2017年南岳发射台以建新塔为契机,结合南岳台实际需求,在湖南台大力支持下构建高山台站IP化系统。本文介绍了南岳电视调频发射台IP化信号系统设计思路,以及确保该系统安全运行的对策。
At present, FM radio and television transmission has been fully digitalized. DTTB program is torward to high-definition and bi- direction. The overall system in high-mountain stations needs to keep up with the technological development. Advanced prediction system is in the lace of technological change and the development of the situation. In 2017, Nanyue transmitting station combined with the actual requirement of Nanyue TV Station to build the IP system in high-mountain station under the support of Hunan TV Station. This paper introduces the design idea of the IP system of Nanyue TV Program FM Transmitting Station and the countermeasures for safe system operation.
