1. A method of processing broadcast data in a broadcast transmitter, the method comprising:

  • randomizing broadcast service data;

    first encoding the randomized broadcast service data to add parity data to the randomized broadcast service data;

    second encoding the first-encoded broadcast service data at a code rate of D/E, wherein D<

    E, and wherein D and E are integers equal to or greater than 1, respectively;

    first interleaving the second-encoded broadcast service data;

    second interleaving the first-interleaved broadcast service data;

    encoding signaling data for signaling the broadcast service data;

    third interleaving the encoded signaling data;

    fourth interleaving the third-interleaved signaling data; and

    transmitting a frame,wherein the frame is divided into a data region including the second-interleaved broadcast service data and a first signaling region including the fourth-interleaved signaling data,wherein the frame includes known data,wherein the encoded signaling data includes information for identifying the code rate,wherein the frame is further divided into a second signaling region that is located at a beginning of the frame, andwherein the second signaling region includes at least one symbol that is used for synchronization and channel estimation.
