Abstract
A device providing an emergency alert service via a mobile broadcasting according to one embodiment of the present invention includes an RS frame encoder configured to generate an RS frame, which is a 2nd dimensional data frame, in a manner of performing an RS (Reed-Solomon)-CRC (Cyclic Redundancy Check) encoding on an ensemble comprising a mobile data for a mobile broadcasting service and a service signaling channel containing an access information on the mobile broadcasting service, an RS frame divider configured to divide the generated RS frame into a plurality of RS frame portions, a signaling encoder configured to generate a signaling data comprising a TPC (Transmission Parameter Channel) for signaling a transmission parameter of the mobile broadcasting and a FIC (Fast Information Channel) containing a connection information between the ensemble and the broadcasting service, a data group formatter configured to generate a data group containing a part of the signaling data and the RS frame portion, and a broadcasting signal generating unit configured to generate a mobile broadcasting signal containing the data group.

19. A method of providing an emergency alert in a broadcast transmitter, the method comprising:
-
generating service data of broadcast services; generating service acquisition data including information for service acquisition of the broadcast services; generating wake-up information indicating whether a broadcast receiver is to be woken up when the broadcast receiver is in a standby mode; transmitting a broadcast signal including the service data, an emergency alert message, the service acquisition data and the wake-up information, wherein the wake-up information indicates a wake-up call for a corresponding emergency, which is distinguished from a previous wake-up call for a concurrent emergency that was dismissed by a user, wherein the wake-up information allows the broadcast receiver to distinguish the wake-up call from the previous wake-up call by being incremented sequentially. - View Dependent Claims (20, 21, 22, 23)

24. An apparatus for providing an emergency alert as a broadcast transmitter, the apparatus comprising:
-
an encoder that generates service data of broadcast services, service acquisition data including information for service acquisition of the broadcast services and wake-up information indicating whether a broadcast receiver is to be woken up when the broadcast receiver is in a standby mode; and a transmitting unit that transmits a broadcast signal including the service data, an emergency alert message, the service acquisition data and the wake-up information, wherein the wake-up information indicates a wake-up call for a corresponding emergency, which is distinguished from a previous wake-up call for a concurrent emergency that was dismissed by a user, wherein the wake-up information allows the broadcast receiver to distinguish the wake-up call from the previous wake-up call by being incremented sequentially. - View Dependent Claims (25, 26, 27, 28)
