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。
In multimedia presentation systems and multimedia electronic conferencing systems, home appliances such as video cameras, video recorders, stereos and the like are an integral part (at least for a considerable period of time). However, the multimedia cards currently used in computers only have data interfaces to these devices, and no control interfaces exist. In this paper, two solutions are proposed and successfully applied to multimedia presentation system. At present, no similar products have been found in China.
