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

  • performing RS encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data by a Reed Solomon (RS) encoder to generate an RS frame belonging to an ensemble, the ensemble comprising a signaling information table including access information of the mobile service data and identification information for identifying a stream where keys to decrypt the mobile service data are obtained;

    mapping a portion of data in the RS frame to a group that includes known data sequences, fast information channel (FIC) data, and transmission parameter channel (TPC) data, the FIC data including information for rapid mobile service acquisition and the TPC data including FIC version information for indicating an update of the FIC data; and

    transmitting a broadcast signal including the group,wherein the group is formed of data blocks,wherein a first known data sequence of the known data sequences is inserted into a third data block of the data blocks,wherein a second known data sequence and a third known data sequence of the known data sequences are inserted into a fourth data block of the data blocks,wherein a fourth known data sequence of the known data sequences is inserted into a fifth data block of the data blocks,wherein a fifth known data sequence of the known data sequences is inserted into a sixth data block of the data blocks, andwherein a sixth known data sequence of the known data sequences is inserted into a seventh data block of the data blocks.
