目的：高质量运动图像的传输是远程医疗的关键，它需要超越地理边界的医疗技术和医疗保健标准化。本研究的目的是建立一个宽带医疗网络之间的医院在韩国和日本使用数字视频传输系统（DVTS）通过互联网协议。方法：我们使用了亚太互联网基础设施（APII）和九州GigaPOP（QGPOP）（日本方面），韩国高级研究网络（韩国方面）和韩日有线网络（国际线路）。我们进行了韩日医疗电话会议与双向传输的DVTS流在IPv4网络。结果：通过互联网协议与DVTS成功地进行了电话会议和手术视频传输。我们可以为一条传输线保留足够的30 Mbps带宽。传输的运动图像的质量在每秒30帧的速率下没有帧丢失。声音也很清晰，时间延迟小于0.01秒。结论：我们已经建立了一个国际医疗网络，通过互联网协议传输高质量的视频，这是易于执行，可靠，也经济。这将是两国远程医疗和未来全球远程医疗通信的一个有前途的工具。
Aim: Transmission of high quality moving-image is essential for telemedicine, which needs standardization of medical techniques and healthcare beyond geographical borders. The aim of this study is to establish a broad-banded medical network between hospitals in Korea and Japan using Digital Video Transport System (DVTS) over Internet protocol. Method: We used Asia Pacific Internet Infrastructure(APII) and Kyushu GigaPOP (QGPOP) (Japanese side), the Korea Advanced Research Network (Korean side), and the Korea-Japan Cable Network (international line). We performed Korea-Japan medical teleconferences with bi-directional transmission by DVTS streaming on IPv4 network. Results: The teleconference and surgical video transmission with DVTS over Internet protocol was successfully performed. We could keep enough bandwidth of 30 Mbps for a line of transmission. The quality of the transmitted moving image had no frame loss with the rate of 30 per second. The sound was also clear and the time delay was less than 0.01 sec. Conclusion: We have established an international medical network with high-quality video transmission over Internet protocol, which is easy to perform, reliable, and also economical. This will be a promising tool in remote medicine for the two countries and for worldwide telemedical communication in the future.
