| 摘要 |
The present invention relates to a data processing apparatus and a data processing apparatus which can improve the tolerance to an error of a code bit of an LDPC code such as burst errors or erasure. An LDPC encoding section 21 carries out LDPC encoding in accordance with a parity check matrix in which a parity matrix which is a portion corresponding to parity bits of an LDPC (Low Density Parity Check) code has a staircase structure, and outputs an LDPC code. A parity interleaver 23 carries out parity interleave of interleaving the parity bits of the LDPC code outputted from the LDPC encoding section 21 to the positions of other parity bits. The present invention can be applied, for example, to a transmission apparatus which transmits an LDPC code.
