Xlet-based applications for Seismic Early Warning and Emergency Services in the IDTV environment

Xlets are Java applets that are developed for interactive digital television broadcasting. In this paper, I will explain the methods that I used for the creation of Xlet-based applications which utilize online data processing in the IDTV broadcasting environment. The themes that I chose for these Xlets are the Earthquake and Tsunami Early Warning application, the Recent Seismic Activity Report application, and the Emergency Services application. The online data regarding the Recent Seismic Activity Report application are provided by the Kandilli Observatory and Earthquake Research Institute (KOERI) of Bo\u11fazi\ue7i University in Istanbul; while the online data for the Earthquake and Tsunami Early Warning application and the Emergency Services application are provided by the Godoro website which I used for storing (and retrieving by the Xlets) the earthquake and tsunami early warning simulation data, and the DVB network subscriber data for utilizing the emergency services (Police, Ambulance and Fire Department.) The main research question of this paper is how to use digital television as a medium to convey timely and pervasive information regarding seismic warning data to disaster-stricken communities
