地震與海嘯等天災造成大規模的損失,各國紛紛發展快速傳遞警報的方式.其中DVB-T(數位電視廣播)就被視為一個不錯的方式. 本文的作者延續其他人的研究,利用DVB-T中定義的Announce Service標準設計了一個XML格式,用以傳遞緊急訊息. 同時透過區域廣播站台廣播站台ID的方式,讓使用者的機上盒可以自動設定所在的區域.

Abstract: Indonesia has the potential to natural disasters, especially the tsunami and earthquake. This is because the position of Indonesia is located on 3 major fire plates which is the Mediterranean plate, Pacific Plate and the Australian plate hence, disaster emergency warning system is absolutely necessary in Indonesia. Reviewing the disaster emergency warning system standard, ISDB and DMB has successfully create a standard and message architecture for the disaster warning whereas DVB has an optional Service Information called Announcement Service for this situation. However, during the digital television transition Indonesia, it required disaster mechanism that can cover Indonesia area and can add some information that case to Indonesia. In this study, we propose a disaster emergency warning system standard for DVB which contain message flow architecture and transmitter and receiver standard. This standard is proposed for the requirement of digital TV transition in Indonesia. This study creates a disaster warning system prototype which contain multiplexer server, set-top-boxes and message flow architecture for alerting the disaster.
