远程高清手术示教系统构建

摘要

The paper uses computer multimedia technology to collect and switch audio and video signals, constructs the remote High Definition ( HD) surgery demonstration system which supports live broadcast, recorded broadcast, rebroadcast and video-on-demand depending on the network communication routing technology.It introduces functions, design scheme and composition of the system and points out that the system can realize HD video transmission and video talkback between the surgery scene and the classroom.Thus, tech-nical level of clinical surgery teaching can be enhanced.%利用计算机多媒体技术采集并转换音、视频信号，通过网络通信路由技术实现音、视频文件的直播、录播、转播和点播，建立远程高清手术示教系统。介绍系统功能、设计方案及组成，指出该系统实现手术现场以及示教室的高清视频传输和语音对讲，提高临床手术教学的技术水平。
