摘　　要：发射台广播电视信号传输对于广播电视播放至关重要,要结合发射台广播电视节目信号传输链路的实际情况,探讨和分析广播电视节目信号源传输系统的建设路径,基于信号编码、复用、监测等原理和设备性能前提,构建广播电视节目信号源——传输——发射机房的统一链路,以更好地扩大发射台广播电视节目信号的传输覆盖面,实现对广播电视节目信号的集中传送和监测。Transmission of radio and television signals at transmitting stations is very important for broadcasting.Combining with the actual situation of transmission links of radio and television signals at transmitting stations,this paper discusses and analyzes the construction path of transmission system of radio and television signal sources,and constructs a unified link of radio and television signal sourcestransmission-transmitter room based on the principles of signal coding,multiplexing and monitoring,so as to better expand the transmission coverage of radio and television signals at transmitting stations and realize centralized transmission and monitoring of radio and television signals.
