This technology pertains to a data processing device and data processing method which are capable of providing an LDPC code having a favorable error rate. This LDPC encoder encodes at a code length of 64,800 bits and at a 7/30, 8/30, 9/30, 10/30 or 11/30 LDPC code rate. The LDPC code contains information bits and parity bits, and a check matrix (H) is configured from an information matrix section corresponding to the information bits of the LDPC code, and a parity matrix section corresponding to the parity bits. The information matrix section of the check matrix (H) is represented by a check matrix initial value table expressing the position of one element of the information matrix section for each of 360 rows. This technology can be applied in cases when conducting LDPC encoding and LDPC decoding. |
