Transmission of emergency alert information using a broadcasting service in an appropriate manner is achieved. A transmitter 200 (broadcasting station) inserts a wake-up signal as signaling of emergency alert information, describes information including a scale (category), type, occurrence time, and occurrence position of disaster, and version information as a message of emergency alert information, and transmits the message using a packet structure of a physical layer. A simple and inexpensive receiver 300 equipped with only a receiving antenna for broadcasting and a demodulator can receive the message of emergency alert information. An evacuation direction and a map or route to a shelter can be displayed using digital signage or streetlights, and an evacuation route can be instructed using streetlights.
