1. A method for processing a broadcast signal in a transmitting system, the method comprising:

  • performing Reed Solomon-Cyclic Redundancy Check (RS-CRC) encoding on mobile service data containing an emergency alert message and generating an RS frame belonging to an ensemble;

    dividing the RS frame into a plurality of RS frame portions;

    mapping the RS frame portions into each of data groups and inserting one fast information channel (FIC) segment and a plurality of known data sequences into each of the data groups;

    performing trellis encoding on data of the data groups; and

    transmitting the broadcast signal including the trellis-encoded data,wherein an FIC chunk is configured with an FIC chunk header and FIC chunk payload, signals biding information between the ensemble and a mobile service included in the ensemble, and is divided into a plurality of FIC segment payloads, wherein the FIC segment is configured with an FIC segment header and one of the plurality of FIC segment payloads, and wherein the FIC segment header comprises wake-up indication information for compulsorily switching a broadcast receiver to an active mode according to a degree of severity of the emergency alert message.
