    Abstract: The present technology relates to a data processing device and a data processing method, which are capable of securing excellent communication quality in data transmission using an LDPC code. In group-wise interleave, an LDPC code in which a code length N is 16200 bits and an encoding rate r is 10/15 or 12/15 is interleaved in units of bit groups of 360 bits. In group-wise deinterleave, a sequence of the LDPC code that has undergone the group-wise interleave is restored to an original sequence. For example, the present technology can be applied to a technique of performing data transmission using an LDPC code.

    Abstract: A data processing apparatus includes a group-wise interleaving unit that performs group-wise interleaving; and a block interleaving unit that performs block interleaving in such a manner that an LDPC code obtained by performing the group-wise interleaving is written in m number of columns as storage regions arranged in the row direction. A type of the block interleaving includes a type A and a type B. A MODCOD which is a combination of the LDPC code and the modulation scheme includes a MODCOD-A which is a MODCOD based on the assumption that the block interleaving of the type A is performed, and a MDOCOD-B which is a MDOCOD based on the assumption that the block interleaving of the type B is performed.

The technology can be applied to a case of transmitting data using the LDPC code. The data processing device and data processing method can ensure excellent communication quality in data transmission using an LDPC code.
