1. A method of transmitting a broadcast signal, comprising:
- storing a low-density parity check (LDPC) codeword having a length of 16200 and a code rate of 10/15;
generating interleaved codeword by interleaving the LDPC codeword on a bit group basis, the size of the bit group corresponding to a parallel factor of the LDPC codeword; and
performing 256-symbol mapping for generating a broadcast signal after generating the interleaved codeword; and
transmitting the broadcast signal over a physical channel.

Abstract
A bit interleaver, a bit-interleaved coded modulation (BICM) device and a bit interleaving method are disclosed herein. The bit interleaver includes a first memory, a processor, and a second memory. The first memory stores a low-density parity check (LDPC) codeword having a length of 16200 and a code rate of 10/15. The processor generates an interleaved codeword by interleaving the LDPC codeword on a bit group basis. The size of the bit group corresponds to a parallel factor of the LDPC codeword. The second memory provides the interleaved codeword to a modulator for 256-symbol mapping.
