The present invention is related to a data processing device and a data processing method, as well as an encoding device and an encoding method which can improve a tolerance to errors. Of an LDPC code which is prescribed in the DVB-S.2 and has a code length of 64,800 and an encoding rate of 2/3, mb code bits are replaced, and the code bits after the replacement become symbol bits of b symbols. When m is 8 and b is 2, where the (i+1)th bit from the most significant bit of 8×2 code bits and 8×2 symbol bits of two successive symbols are represented by band y, respectively, the following replacement for each allocation is carried out: bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, bwith y, and bwith y. The present invention can be applied for instance to a transmission system to transmit the LDPC code etc. |
