1. A relay device configured to relay emergency information to a plurality of mobile terminals, the relay device comprising:
- circuitry configured to;
relay bidirectional communication in a non-emergency mode, the bidirectional communication being in a first format;
receive a broadcast signal that is in a second format and includes the emergency information;
change an operation mode of the relay device from the non-emergency mode to an emergency mode, in response to an emergency flag being carried in the received broadcast signal, the emergency mode being different than the non-emergency mode;
broadcast a predetermined identifier to the plurality of mobile terminals when the operation mode of the relay device is in the emergency mode, the predetermined identifier identifying the relay device; and
provide the emergency information, received in the broadcast signal in the second format, to the plurality of mobile terminals via communication in the first format when the operation mode of the relay device is in the emergency mode, whereinthe second format is an Advanced Television Systems Committee (ATSC) digital terrestrial television standard, andthe second format is different from the first format.
