Abstract:
PURPOSE: A disaster broadcast providing apparatus and a method thereof are provided to provide a disaster broadcast service only in an area where a disaster situation is generated. CONSTITUTION: A control unit of a monitoring unit relays a digital multimedia broadcasting (DMB) signal to a broadcast receiver which is in a signal reaching range. The control unit receives one or more data which are measured in a sensor which is installed in a specific location. The disaster situation determining unit of the monitoring unit determines a disaster situation based on the one or more data. A wake-up generating unit generates a disaster broadcast signal and a wake-up signal in order to wake up the broadcast receiver which is in a broadcast termination mode when a disaster situation is generated (S612). A wake-up synthesizing unit transmits the disaster broadcast signal and the wake-up signal by disconnecting the relay of the DMB broadcast signal (S614).
