Abstract
A method is provided for transmitting an emergency alert message by a broadcast transmitter. The broadcast transmitter first encodes service data and signaling data for a service, second encodes the first encoded service data and the first encoded signaling data, and Forward Error Correction (FEC) encodes transmission parameter data. The transmission parameter data includes encoding information of the service data. The broadcast transmitter modulates the second encoded service data, the second encoded signaling data, and the FEC encoded transmission parameter data, and transmits a broadcast signal including the modulated service data, the modulated signaling data, and the modulated transmission parameter data. The signaling data includes a first signaling table and a second signaling table.
