Claim:
1. An apparatus for transmitting broadcast signals, the apparatus including: an input processor to process service data; an encoder to encode the service data according to a 16200 bit codeword and a 13/15 code rate based on a parity check matrix; a frame builder to build at least one signal frame by mapping the encoded service data; a modulator to modulate data in the built at least one signal frame by an Orthogonal Frequency Division Multiplexing (OFDM) scheme; and a transmitter to transmit the broadcast signals having the modulated data, wherein the parity check matrix is wherein each row corresponds to each group of 360 information bits, and wherein each value in each row represents an address of a parity bit to be calculated.
