Abstract: The present technology relates to a transmission device, a transmission method, a reception device, and a reception method for securing good communication quality in data transmission using an LDPC code.The LDPC coding is performed on the basis of the parity check matrix of the LDPC code with the code length N of 17280 bits and the coding rate r of 5/16, 6/16, or 7/16. The parity check matrix includes an A matrix of M1 rows and K columns expressed by a predetermined value M1 and an information length K=N×r of the LDPC code, a B matrix of M1 rows and M1 columns having a step structure, a Z matrix being a zero matrix of M1 rows and N−K−M1 columns, a C matrix of N−K−M1 rows and K+M1 columns, and a D matrix being an identity matrix of N−K−M1 rows and N−K−M1 columns. The A matrix and the C matrix are represented by a parity check matrix initial value table, and the parity check matrix initial value table is a table representing positions of elements of 1 of the A matrix and the C matrix for every 360 columns. The present technology can be applied to, for example, data transmission using an LDPC code.

Abstract: The present technology relates to a transmission method and a reception device for securing favorable communication quality in data transmission using an LDPC code.In group-wise interleaving, the LDPC code with a code length N of 69120 bits is interleaved in units of 360-bit bit groups. In group-wise deinterleaving, a sequence of the LDPC code after group-wise interleaving is returned to an original sequence. The present technology can be applied, for example, in a case of performing data transmission using an LDPC code, and the like.

Abstract: The present invention relates to a data processor and data processing method that facilitate properly processing a stream. An input stream is formed by a plurality of packets . Each of the packets of the input stream is distributed to one of a plurality of channels and null packets (NP) are distributed to the other channels. This divides the input stream into divided streams on a plurality of channels including the packets of the input stream at a predetermined density. The present invention can be used, for example, for a channel bonding (CB) technique in which an input stream is divided into a plurality of channels and transmitted.
