To enable reliable receipt of an emergency broadcast transmitted by a digital television in the event of a disaster, such as an earthquake, and diminish electric power consumed in a standby condition where an emergency broadcast is not transmitted. In the event of a disaster, such as an earthquake, a Meteorological Agency' s server 3 commands a broadcast station 8 to commence an emergency broadcast and notifies an emergency broadcast receiving information distribution server 5 of seismic information by way of the Internet 3 and a portable cellular phone network 4. The emergency broadcast receiving information distribution server 5 distributes emergency broadcast receiving information to a portable cellular phone 1 equipped with a television receiver by way of a portable cellular phone base station 6 located in an area hit by an earthquake. When received portable radio communication includes emergency broadcast receiving information, the portable cellular phone 1 equipped with a television receiver activates a television broadcast receiving circuit, to thus receive an emergency broadcast from the broadcast station 6. When the thus-received broadcast includes an emergency broadcast receiving command, all circuits having a television receiving function are activated, to thus play back an emergency broadcast.
