Abstract: A receiver that receives a broadcast signal including service data of a broadcast service and an emergency alert table including an emergency alert message, a first decoder that decodes the service data, a second decoder that decodes the emergency alert table, and a display processor that displays the broadcast service including the decoded service data and emergency alert message in the decoded emergency alert table. The display processor further displays information to notify that an additional content related to the emergency alert message is present, and the display processor further displays the additional content based on a selection of the information by a user. The broadcast signal further includes wake-up information, where a value of the wake-up information is changed from 0 to 1 based on a wake-up call, and the value of the wake-up information is changed from 1 to 2 based on a different wake-up call.
