The present technology relates to a transmission method and a reception device that can ensure good communication quality in data transmission using an LDPC code. In groupwise interleave, LDPC codes having a code length N of 69120 bits are interleaved in units of 360 bits. In the groupwise deinterleave, the arrangement of the LDPC codes after the groupwise interleaving is returned to the original arrangement. This technique can be applied, for example, when performing data transmission using an LDPC code. |
