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.

Abstract: A data processing device includes a splitter in which an input stream made up of a plurality of packets is split, so as to generate split streams of a plurality of channels, of which the smallest increment is base band frames (BBFs) where the packets of the input stream are placed in consecutive order in a data field of the BBF which is the object of forward error correction (FEC).

Abstract: The present technology relates to a data processing device and a data processing method capable of performing appropriate stream processing.An input stream is split into a split stream for each of a plurality of channels. A stream to be generated includes the split stream, and signature information unique for each of the input streams containing the split stream, or includes the split stream, the signature information, and location information about a transmission frequency band of a split stream constituting the input stream and different from the split stream included in the generated stream. The present technology is applicable to a channel bonding (CB) technology which splits an input stream into streams of a plurality of channels and transmits the split streams, for example.
