摘要
研究计算机通过利用双音多频码(即DTMF码)进行控制的多媒体集中控制系统的工作原理,运用计算机声卡播放DTMF双音多频信号来控制多媒体仪器设备,实现多媒体控制器的全部功能,方法简单可靠,使多媒体集中控制系统完全自动化。
The working principle of multi-media centralized control system controlled by the computer by using the DTMF（dual tone multi-frequency） technique is introduced. The sound card is used to play the DTMF signal in order to control the multi-medla equipment and realize all the functions of the multi-media controller. The method is simple and reliable, and the multi-media centralized control system can work automatically.
