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

  • encoding the broadcast data by adding parity data;

    interleaving the encoded broadcast data;

    encoding first signaling data;

    allocating the interleaved broadcast data and the encoded first signaling data to frames;

    modulating the frames; and

    transmitting a broadcast signal carrying the modulated frames,wherein the first signaling data includes a code rate for encoding the broadcast data and information related to fast service acquisition information,wherein the fast service acquisition information allows a receiver to quickly locate upper layer signaling information,wherein the modulated frames include link layer packets,wherein the link layer packets carry service signaling data for discovering a service provided by the encoded broadcast data,wherein the link layer packets further carry Internet Protocol (IP) packets, andwherein the IP packets carry Asynchronous Layered Coding (ALC)/Layered Coding Transport (LCT) packets that include the broadcast data.
