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

  • performing Reed-Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data to build an RS frame;

    dividing the RS frame into a plurality of portions;

    mapping one of the plurality of portions into a first data group and adding known data sequences and place holders for moving picture experts group (MPEG) header data to the first data group,wherein the first data group comprises a first region and a second region,wherein the first region comprises;

    an Nth segment comprising K mobile service data bytes,an (N+1)th segment comprising L mobile service data bytes, andan (N+2)th segment comprising M mobile service data bytes,wherein the second region comprises;

    an Oth segment comprising X mobile service data bytes,an (O+1)th segment comprising Y mobile service data bytes, andan (O+2)th segment comprising Z mobile service data bytes,wherein the variables K, L, M, N, O, X, Y, Z are integers greater than 0, andwherein K<

    L<

    M, X=Y=Z, and N<

    O;

    deinterleaving, by a deinterleaver, data in the first data group to output a second data group;

    replacing, by a packet formatter, the place holders for MPEG data in the second data group MPEG header data, such that mobile service data packets are output; and

    interleaving, by an interleaver, data in the mobile service data packets.
