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 processing an emergency alert service in a broadcasting transmitter, comprising:
-
FEC (Forward Error Correction) encoding broadcast service data; encoding transmission parameters for transmission of the broadcast service data, wherein the transmission parameter includes a wake-up information indicating whether a broadcasting receiver is to be woken up when the broadcasting receiver is in a standby mode, and provides an emergency alert message; generating data frames including the encoded broadcast service data, and transmission parameters; and transmitting the broadcast signals including the data frames, the emergency alert message and service acquisition data, wherein the service acquisition data carries information to enable service acquisition. - View Dependent Claims (20, 21, 22)
