1. A method of transmitting broadcast data, the method comprising:

  • processing with input streams to output transmission units, wherein the transmission units carry broadcast data which carries a service or a service component;

    encoding the transmission units;

    symbol-mapping the encoded transmission units;

    Multi Input Multi Output (MIMO) encoding the symbol-mapped transmission units;

    time-interleaving the MIMO-encoded transmission units;

    building signal frames including the time-interleaved transmission units;

    modulating the built signal frames by Orthogonal Frequency Division Multiplexing (OFDM) scheme; and

    transmitting the modulated signal frames,wherein a signal frame among signal frames includes a preamble part, the preamble part includes physical signaling data for the transmission units, andwherein the signal frame further includes mapping information between IP packets and the transmission units for transmitting at least one service component, and compression information of the IP packets when the input streams are the IP packets.
