1. A broadcast signal transmitting apparatus comprising:
an encoder configured to encode input bits to generate parity bits based on a low density parity check (LDPC) code;
a group interleaver configured to split a codeword comprising the input bits and the parity bits into bit groups, and interleave the bit groups;
a block interleaver configured to write bits of the interleaved bit groups to columns, each of the columns comprising a first part and a second part, and read the written bits from the columns;
a constellation mapper configured to map the read bits to constellation points based on a modulation method; and
a transmitter configured to transmit a broadcast signal which is generated based on the constellation points to a receiving apparatus,
wherein the modulation method is one of quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM), 64-QAM and 256-QAM,
wherein at least one first bit group of the interleaved bit groups is interleaved in the first part and at least one second bit group of the interleaved bit groups is interleaved in the second part, and
wherein the each of the columns is divided into the first part and the second part based on the modulation method for the mapping and a number of the bit groups.
