MDTV Telemedicine Project: Technical Considerations in Videoconferencing for Medical Applications

Abstract

In spite of the many advances in technology, complex problems must be addressed in establishing and maintaining a telemedicine system. Although most such systems are built around interactive videoconferencing (IAVC) equipment, clinical requirements dictate that these systems offer more than traditional IAVC systems. Input from system users should be obtained early in the design process to ensure the functionality necessary to achieve maximum utilization. Surprisingly, audio, rather than video, signals may present the greatest challenge to achieving consistent, high-quality videoconferencing encounters. Audio technical problems can be frustrating for patients and providers alike and can undermine user confidence in IAVC as a vehicle for healthcare delivery. A capability for remote access and control of components at distant sites seems essential to providing cost-effective and technically reliable service.
