广播电台播出系统的数字化改造

Digitalization of Broadcasting System in Radio Station

随着广播电视技术和数字技术、网络技术的发展,传统的模拟广播播出系统的技术指标和系统构架已不能满足广播发展的需要,广播电台播出系统的数字化成为必然趋势。本文介绍广播系统的数字化改造设计与实践,改造后的系统信号传输安全性、可靠性、稳定性都达到较高的水准,音频质量和技术指标得到了很大的改善。

Along with the development of broadcasting technology, digital technology and network technology, the traditional framework of AM/ FM radio broadcasting system cannot meet the demand of broadcasting development. Therefore, a digitalized broadcasting system is needed. The audio quality and technical indexes could be improved. The safety, reliability and stability of digital signal transmission will be upgraded.
