台州广电有线前端优化电视信号传输通道的设计与实现

The Design and Implementation of the Optimization of TV Signal Transmission Channel in Headend Room of Taizhou Radio and Television

前端机房是安全播出保障的核心,必须经过充分的事前规划才能进行优化,技术人员要充分评估方案的可行性,并在优化工作过程中始终应该保持认真细致的工作态度。主要阐述了台州广电数字电视射频信号线路优化的设计和实现、优化前后射频信号线路的分析与对比、以及常用测量方法和工具的示例。

The headend room is the core of guaranteeing secure broadcast,which thus requires full prior planning to be optimized. Technicians must fully assess the feasibility of the program and always keep a careful and meticulous work attitude in the optmization process. This paper mainly describes the design and implementation of the optimization of Taizhou radio and television digital TV radio frequency signal line,the analysis and comparison of the radio frequency signal line before and after optimization,and the common measurement methods and tools.
