Data processing device and data processing method

A method performed by a receiving device receiving digital television signals, the method comprising:

• receiving encoded data, each 8 bits of which mapped to one of 256 signal points of a modulation method;
• processing the encoded data to produce a group-wise interleaved low density parity check (LDPC) codeword;
• processing the group-wise interleaved LDPC codeword in a unit of a bit group of 360 bits to produce an LDPC codeword of an LDPC code;
• wherein an (i+1)-th bit group from a head of the LDPC codeword of the LDPC code is indicated by a bit group i, the LDPC codeword of the LDPC code has a sequence of bit groups 0 to 179, and the group-wise interleaved LDPC codeword has a following sequence of bit groups,
