由于护理示教对动作演示画面的连续性和清晰度要求较高，采用H．264视频压缩技术，通过IP网络传输的传统示教系统在多路大规模传输高清视频的时候会造成演示画面不连续并且延时严重，无法满足护理示教演示需求。根据护理示教的单向视频质量要求较高的特点，我们采用非压缩视频技术，光纤加网络双路传输方案：用光纤传输非压缩高清示教视频，通过光纤矩阵切换器调度信号，语音及教室监控视频数据通过IP网络传输，较好地满足了护理实训示教要求，收到较好效果。

Nursing demonstrative teaching has high requirements for continuity and definition of motion demonstration images .Therefore, when H.264 video compression technology is used in the traditional demonstrative teaching through IP network transmission , it causes discontinuity and serious delay of demonstration images in multiple large-scale high-definition (HD) video transmission.So this technology cannot meet the demand of nursing demonstrative teaching .Based on high requirements of nursing demonstrative teaching for one-way video quality , we used the uncompressed video technology and optical fiber-network two-way transmission scheme .The optical fibers transmit uncompressed HD videos; fiber matrix switcher dispatches signals; and IP network transmits speech and classroom monitoring video data .This scheme can better meet the requirements of nursing demonstrative teaching and bring satisfactory results .
