随着我市县的有线电视全面实现村村通,为农村有线广播利用HFC网络实现调频共缆传输提供了保证。利用HFC网络实现调频传输不但节约了投资,而且从根本上改善了音质,提高了传输的可靠性,当前我市县、乡镇自用调频同频插播系统已全面实现了FM广播与有线电视信号共缆传输。本文就是针对调频同频插播系统这一问题,通过对我市的调频同频插播系统的介绍,提出了一些独创性见解供大家参考。
With the full realization of cable television in our county and village villages, it provides a guarantee for the use of HFC network in rural cable broadcasting to realize the transmission of FM cable. The use of HFC network to achieve FM transmission not only saves investment but also fundamentally improves the sound quality and improves the reliability of transmission. At present, metropolitan and township self-use FM inter-frequency broadcast system has fully realized the FM broadcast and CATV signal cable transmission. This article is for the same frequency FM broadcast system this issue, through the city’s FM simultaneous broadcast system introduced some original ideas for your reference.
