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.
