1. A receiving system comprising:

  • a demodulator receiving a broadcast signal including mobile service data and main service data, the demodulator converting the received broadcast signal to a baseband signal, the mobile service data configuring a data group, the data group including a plurality of know data sequences;

    a known data detector detecting a location of at least one of the known data sequence within the data group, the known data detector outputting detected known data location information;

    an equalizer channel-equalizing the demodulated mobile service data using the detected known data location information;

    a signaling decoder reconstructing transmission parameter channel (TPC) data and fast information channel (FIC) data received by being included in a signaling information area allocated between a first known data sequence and a second known data sequence among a plurality of the known data sequences; and

    a controller receiving the detected known data location information and the TPC data, the controller generating to output at least one selected from the group consisting of a presence or non-presence of the data group of a selected parade, location information of a different known data sequence within the data group, SCCC relevant information and RS frame relevant information.
