These information streams can support both continuous monitoring and emergency situations. According to this scenario the authors have developed and implemented the mobile communication system which is described in this paper. The system is based on ITU-T H.323 multimedia terminal recommendation suitable for real-time data video audio and telemedical applications. The audio and video codecs respectively H.264 and G723.1 were implemented and optimized in order to obtain high performance on the system target processors. Offline media streaming storage and retrieval functionalities were supported by integrating a relational database in the hospital central system. The system is based on low-cost consumer technologies such as general packet radio service GPRS and wireless local area network WLAN or WiFi for lowband data video transmission. Implementation and testing were carried out for medical emergency and telemedicine application. In this paper the emergency case study is described. Copyright 2007 Ivano Barbieri et al.
