    • 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). [Reference numerals] (AA) No; (BB) Yes; (S600) Receive a signal that a disaster occurs; (S602) Receive a service stream for the situation of the disaster; (S604) Encoding and multiplexing; (S606) Generate a disaster broadcast signal; (S608) Transmit the disaster broadcast signal; (S610) Receive a wake-up request signal?; (S612) Generate a wake-up signal; (S614) Synthesize and transmit the wake-up signal; (S616) Transmit the synthesized signal
    • 目的:提供灾难广播提供装置及其方法,仅在产生灾害情况的区域提供灾难广播服务。 构成:监视单元的控制单元将数字多媒体广播(DMB)信号中继到信号达到范围的广播接收机。 控制单元接收在安装在特定位置的传感器中测量的一个或多个数据。 监视单元的灾害情况决定单元基于一个以上的数据来决定灾害情况。 唤醒发生单元产生灾难广播信号和唤醒信号,以便在产生灾害情况时唤醒处于广播终止模式的广播接收机(S612)。 唤醒合成单元通过断开DMB广播信号的中继来发送灾难广播信号和唤醒信号(S614)。 (附图标记)(AA)否; (BB)是的; (S600)接收到发生灾难的信号; (S602)接收灾难情况的服务流; (S604)编码和复用; (S606)生成灾难广播信号; (S608)发送灾难广播信号; (S610)接收唤醒请求信号? (S612)产生唤醒信号; (S614)合成并发送唤醒信号; (S616)发送合成信号
