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

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. LDPC coding for information bits with an information length K=N×r is performed on the basis of an extended parity check matrix having rows and columns each extended by a predetermined puncture length L with respect to a parity check matrix of an LDPC code with a code length N of 69120 bits and a coding rate r of 14/16, so that an extended LDPC code having parity bits with a parity length M=N+L−K is generated. Then, a head of the information bits of the extended LDPC code is punctured by a puncture length L, so that a punctured LDPC code with the code length N of 69120 bits and the coding rate r is generated. The extended parity check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits. The present technology can be applied to, for example, data transmission using an LDPC code.

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 12/15, 6/15, or 8/15 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 coding and modulation apparatus and method are presented. The apparatus comprises an encoder that encodes input data into cell words, and a modulator that modulates said cell words into constellation values of a non-uniform constellation. The modulator is configured to use, based on the total number M of constellation points of the constellation and the code rate, a non-uniform constellation from one or several groups of constellations each comprising one or more constellations.
