A data processing method comprising:

• a group-wise deinterleaving step of returning a sequence of an LDPC code, which has been subjected to group-wise interleaving and is obtained from data transmitted from a transmitting device, to an original sequence,
• wherein the transmitting device includes:
• a coding unit that performs LDPC coding on the basis of a parity check matrix of the LDPC code having a code length N of 64800 bits and a coding rate r of 11/15;
• a group-wise interleaving unit that performs the group-wise interleaving which interleaves the LDPC code in a unit of a bit group of 360 bits;
• and
• a mapping unit that maps the LDPC code to any one of four signal points which are determined by a modulation method in a unit of 2 bits,
• in the group-wise interleaving, an (i+1)-th bit group from a head of the LDPC code is set as a bit group i and a sequence of bit groups 0 to 179 of the 64800-bit LDPC code is interleaved into a sequence of the following bit groups,
• 0, 14, 19, 21, 2, 11, 22, 9, 8, 7, 16, 3, 26, 24, 27, 80, 100, 121, 107, 31, 36, 42, 46, 49, 75, 93, 127, 95, 119, 73, 61, 63, 117, 89, 99, 129, 52, 111, 124, 48, 122, 82, 106, 91, 92, 71, 103, 102, 81, 113, 101, 97, 33, 115, 59, 112, 90, 51, 126, 85, 123, 40, 83, 53, 69, 70, 132, 134, 136, 138, 140, 142, 144, 146, 148, 150, 152, 154, 156, 158, 160, 162, 164, 166, 168, 170, 172, 174, 176, 178, 4, 5, 10, 12, 20, 6, 18, 13, 17, 15, 1, 29, 28, 23, 25, 67, 116, 66, 104, 44, 50, 47, 84, 76, 65, 130, 56, 128, 77, 39, 94, 87, 120, 62, 88, 74, 35, 110, 131, 98, 60, 37, 45, 78, 125, 41, 34, 118, 38, 72, 108, 58, 43, 109, 57, 105, 68, 86, 79, 96, 32, 114, 64, 55, 30, 54, 133, 135, 137, 139, 141, 143, 145, 147, 149, 151, 153, 155, 157, 159, 161, 163, 165, 167, 169, 171, 173, 175, 177, 179
• the LDPC code includes information bits and parity bits,
• the parity check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits,
• the information matrix portion is represented by a parity check matrix initial value table, and
• the parity check matrix initial value table indicates positions of elements “1” in the information matrix portion for every 360 columns and includes the following,
