1. A method of processing data in a transmitting system, the method comprising:

  • randomizing enhanced data;

    first encoding the randomized enhanced data to add first parity data for error correction, thereby forming a frame;

    dividing data of the frame into a plurality of groups, wherein the plurality of groups have a same size;

    first interleaving data of each group;

    second interleaving the first-interleaved data; and

    transmitting a broadcast signal including the second-interleaved enhanced data and transmission parameters,wherein second encoding on the randomized enhanced data is selectively performed to add second parity data for error detection, andwherein the transmission parameters include information to indicate whether the second encoding is performed on the enhanced data.
