This technology pertains to a data processing device and a data processing method that make it possible to provide an LDPC code that has a good error rate. An LDPC encoder encodes using an LDPC code that has a code length of 64,800 bits and a code rate of 5/15. Said LDPC code contains information bits and parity bits, and the parity-check matrix (H) for said LDPC code comprises an information-matrix section corresponding to the information bits of said LDPC code and a parity-matrix section corresponding to the parity bits. The information-matrix section of the parity-check matrix (H) is represented by a parity-check-matrix initial-value table that represents the position of one element of said information-matrix section each 360 columns. This technology can be applied when performing LDPC encoding and LDPC decoding. |
