摘　　要：目的数字化手术室多路高清视频合成对于提高手术教学及手术远程会诊具有重要的意义。方法针对国内现有手术室视频清晰度低、可视角度少、切换繁琐等问题,采用现场可编程门阵列(field-progtammable gatearray,FPGA)硬件架构,设计了四路HD-SDI高清视频信号的合成,现场测试。结果系统运行稳定,操作方便。结论设计和实现手术室内多路高清视频合成系统,是数字化手术室建设的重点和难点。Objective The multiplex high definition video synthesis system for digital operating room is important for improving the quality of medical teaching and tele-surgery. Methods To solve the problems such as lower resolution and less visual angles of video in domestic operating room, a system of four HD-SDI video signals synthesis was designed, with the hardware structure of field-programmable gatearray, and on-site tests were performed. Results The system worked stably, and was convenient for operation. Conclusion Designing and implementing multiplex high definition video synthesis system plays a vital role in the construction of digital operating room.
