TRANSMITTING/RECEIVING SYSTEM AND METHOD FOR PROCESSING A BROADCASTING SIGNAL

摘要

According to the present invention, a method for processing a broadcast signal in a transmitting system that transmits an emergency alert message through a mobile broadcast network comprises the steps of: RS-CRC encoding of mobile service data containing an emergency alert message so as to generate an RS frame that belongs to an ensemble; dividing the RS frame into a plurality of RS frame portions; mapping the plurality of RS frame portions to data groups and inserting one FIC segment, TPC data, and a plurality of base data streams into each data group; trellis-encoding the data of the data groups; and transmitting a broadcast signal comprising the trellis-encoded data. At least one of either a FIC segment header contained in the FIC segment or the TPC data includes wake-up indication information for compulsorily placing a broadcast receiver into an active mode depending on the level of seriousness of the emergency alert message.
