随着数字音频技术的发展,不少电台的节目制播方式在实现模数转换的同时,节目的存储方式也发生了转变,即由模拟音频节目资料存储转为数字音频节目资料存储。在这一趋势下,以数字信号为存储方式的音频节目资料库相应建立,它较模拟音频节目资料库无论是功能上、管理上都有了很大的进步。从系统架构而言,凸现了计算机应用和计算机网络技术,拓宽了传输、交换通路,为自动化播出创造了条件;
With the development of digital audio technology, a lot of broadcasting programs of the radio stations have realized the analog-digital conversion and the storage modes of the programs have also changed. That is, the analog audio program data storage is changed to the digital audio program data storage. Under this trend, a digital audio signal storage program is set up corresponding to the audio program database. Compared with the analog audio program data base, it has made great progress both in function and in management. From the system architecture, highlighting the computer applications and computer network technology, and broaden the transmission and exchange channels, creating the conditions for automatic broadcast;
