In this paper, the real-time telemedicine system based on multimedia data was designed. In order to describe patients to medical specialists, the system included multimedia data. The prototype system designed in this paper effectively integrated multimedia components in a single computer, as well as compromise the compression, interface, medical imaging standards and modular software architectures. The mobile bed was manufactured to improve the movement of the system. Two experiments had been conducted to evaluate the technical functionality and clinical usability. Using the data compression and priority control, the telemedicine system transmitted multimedia data in real-time at the internet and the ethernet network. Inter-hospital experiments and Sang-Am World-Cup Stadium experiments demonstrate the feasibility to be effectively used.
