  • receiving the broadcast signal comprising a data group, the data group comprising fast information channel (FIC) data carrying cross-layer information to enable a fast mobile service acquisition, transmission parameter channel (TPC) data including FIC version information for indicating an update of the FIC data, mobile service data, and a plurality of known data sequences;

    demodulating the received broadcast signal;

    compensating channel distortion generated in the demodulated broadcast signal based upon at least one of the plurality of known data sequences;

    obtaining a first information table including access information of an IP stream of the mobile service data;

    acquiring the IP stream of the mobile service data based upon the obtained first information table; and

    decoding audio or video data delivered through the acquired IP stream of the mobile service data,wherein the TPC and FIC data are encoded with a Parallel Concatenated Convolutional Code (PCCC) encoding method and the mobile service data is encoded with a Serial Concatenated Convolutional Code (SCCC) encoding method.
