Claim Text:
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.
