| 摘 要： | 通过网络医学教学及指导系统，将临床医学活动实况视频图像分别以MPEG2、MPEG4编码同时在局域网或广域网上进行纽播，可适应不同网络带宽的需要，同时实现双向语音或视频，满足临床教学或指导的需要。客户端可部署在局域网或广域网的任意终端上，获得权限后，用户可在任意地点实时收看高清晰手术图像，利用双向音视频系统进行交流，并可远程控制摄像机镜头的角度和焦距以获得理想的收看效果。

| Abstract: | Through the network medical teaching and guidance system,the live video of clinical medicine activity can be multicast by MPEG2 code and MPEG4 code simultaneously on the LAN or WAN.It may meet the request of different network bandwidth,realize the bidirectional audio or video frequency at the same time,and satisfy the clinical teaching or guidance need.The client port can be deployed in the random terminal on LAN or WAN,while the user with the authorization can see the high clear surgery image in real time at any place,make communication through the bidirectional audio and video system,and even remotely control the camera's lens angle and focus for perfect video effect. |
