Apparatus and method for processing an emergency alert service
First Claim
1. A method of processing an emergency alert service in a broadcasting transmitter, comprising:
- performing FEC (Forward Error Correction) encoding on broadcast service data;
generating data frames including the encoded broadcast service data;
inserting transmission parameters for transmission of the broadcast service data into the data frames,wherein the transmission parameters include wake-up information indicating whether a broadcasting receiver is to be woken up when the broadcasting receiver is in a standby mode; and
transmitting a broadcast signal including the data frames, an emergency alert message and service acquisition data, wherein the service acquisition data carries information to enable service acquisition,wherein the wake-up information further indicates a second wake-up call for a second emergency situation, which is different from a first wake-up call for a first emergency situation that was dismissed by the user when the wake-up information signaled the first wake-up call,wherein the wake-up information differentiates the second wake-up call from the first wake-up call by incrementing a value of the wake-up information represented by at least 2 bits, wherein the broadcasting receiver is to be woken up only for the second wake-up call.

Abstract
A device providing an emergency alert service includes an RS frame encoder configured to generate an RS 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, a 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, and a data group formatter configured to generate a data group containing a part of the signaling data and the RS frame portion.
