<p>The present invention is related to a data processing device, a data processing method, a coding device and a coding method that can be configured to improve a tolerance to an error. A code bit of mb bits in an LDPC code having a code length of 64,800 bits and a code rate of 2/3 as prescribed in the DVB-S.2 is replaced and a code bit after the replacement is a symbol bit with b symbols. When m is 8 and b is 2, and code bits with 8x2 bits and (i+1)th bit from the most significant bit of the 8x2 symbol bits of successive two symbols are expressed by bi and yi, respectively, the following replacement for each allocation is carried out: b0 with y15, b1 with y7, b2 with y1, b3 with y5, b4 with y6, b5 with y13, b6 with y11, b7 with y9, b8 with y8, b9 with y14, b10 with y12, b11 with y3, b12 with y0, b13 with y10, b14 with y4, and b15 with y2. The present invention can be applied to a transmission system to transmit the LDPC code, for instance.</p> |
