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

  • encoding broadcast service data for a service at a first code rate;

    block interleaving the encoded broadcast service data;

    convolutional interleaving the block-interleaved broadcast service data;

    first encoding transmission parameters to add parity data to the transmission parameters;

    second encoding the first-encoded transmission parameters at a second code rate; and

    transmitting a frame that includes the convolutional interleaved broadcast service data and the second-encoded transmission parameters,wherein the frame further includes first signaling information and second signaling information which provide information for acquisition of the service,wherein the first signaling information includes information for identifying a broadcast stream within which the broadcast service data are carried, service type information for indicating a type of the service, and information for indicating whether or not the service is hidden,wherein the second signaling information includes Internet Protocol (IP) address information for accessing of the broadcast service data, andwherein the transmission parameters include information for identifying the first code rate and information related to the frame.
