This study demonstrates the feasibility of international telemedicine, establishing a reliable and economical network for high-quality video transmission. The system enables telemedical education and communication across borders.

Area of Science:

  • Medical Education
  • Telecommunications Engineering
  • Surgical Technology

Background:

  • Telemedicine offers remote learning and feedback opportunities but lacks standardized international ethical guidelines.
  • Existing telemedicine systems face limitations in delivering high-quality visual and auditory data for complex procedures.
  • The need for robust international networks for medical education and collaboration is increasingly apparent.

Purpose of the Study:

  • To establish a telemedical education system utilizing high-quality digital image transfer over a high-speed network.
  • To develop and test an international medical network for real-time surgical collaboration and education.
  • To overcome limitations in current telemedicine by ensuring high-fidelity data transmission.

Main Methods:

  • Utilized the Asia Pacific Information Infrastructure (APII) submarine cable and Korea Advanced Research Network (KOREN) for international and domestic connectivity.
  • Implemented Digital Video Transfer System (DVTS) over an IPv4 network for teleconference and video streaming between South Korea and Japan.
  • Established high-speed network connections capable of supporting simultaneous, high-quality video and audio transmissions.

Main Results:

  • Successfully transmitted four endoscopic surgeries with real-time teleconferences between Seoul and Kyushu.
  • Maintained sufficient bandwidth (60 Mbps) for dual-line transmissions, ensuring high-quality video at 30 frames per second with no frame loss.
  • Achieved clear audio transmission with minimal time delay (less than 0.3 seconds).

Conclusions:

  • Demonstrated the feasibility and effectiveness of both domestic and international telemedicine applications.
  • Established a reliable, economical, and easy-to-implement international medical network for high-quality video transmission.
  • The developed network system shows significant promise as a future tool for global telemedical communication and education.
