Abstract
This paper describes the main challenges of implementing a multimedia on demand system (TetraMoD) for emergency scenarios. The objective is to offer a complete solution providing multimedia services (video on demand and reliable file transfer) to rescue teams in an emergency situation. TetraMoD improves traditional emergency communications by integrating TETRA, characterized by wide geographical coverage, and DVBT, characterized by broadband broadcast capability. The system consists of a TetraMoD gateway acting as interface between the two networks, a middleware layer, and the TetraMoD client software terminal. A real scenario using standard protocols (SDP, RTP/RTCP, RTSP, FLUTE) is presented.
