计算机遥控多媒体设备的设计与实现

Design and realization of remote controlling multimedia device

在多媒体演示系统与多媒体电子会议系统中，摄像机、录像机、音响等家电设备是必不可少的组成部分（至少在相当长的一段时间是这样）。然而目前计算机使用的多媒体卡只留有与这些设备的数据接口，而无控制接口。文中提出两种解决方案并成功地应用于多媒体演示系统中，目前国内尚未见有类似的产品。

Camera, video recorder, sound device, etc. are the indispensable device in theMultimedia Presentation System and the Multimedia Electronic Conferencing System. Butcurrent multimedia cards assembled in computers only have data interface with those device, nocontrol interface. This paper puts forward two plans to solve these problems and to be applied tothe Multimedia Presentation System. Currently there are no similar products domestically.
