[Show abstract][Hide abstract] ABSTRACT: 第8回遠隔医療研究会 : 2004(H16)年8月21日：岩手 A broad-banded medical network was established between Korea and Japan using Digital Video Transport System (DVTS) over Internet protocol. We used Kyushu GigaPOP (QGPOP) (Japanese side), the Korea Advanced Research Network (Korean side), and the Korea-Japan Cable Network (international line). The teleconferences with real-time transmission of laparoscopic surgery, neurosurgery, and endoscopic examination were successfully performed. The bandwidth was 30 Mbps for a line of transmission and two lines of DVTS were utilized. The uncompressed moving image had the rate of 30 per second. The security software was also used to protect patient privacy. This international telecommunication using high-quality moving image is very helpful for the exchange of new medical techniques among different countries.
