Abstract
Data processing devices and data process methods that can increase tolerance for data errors. An LDPC encoder performs encoding with an LDPC code having the code length of 16200 bits and one of the six code rates of 1/5, 1/3, 2/5, 4/9, 3/5, and 2/3. The parity check matrix H of the LDPC code is formed by arranging the elements “1” of an information matrix in the column direction in 360-column cycles, the information matrix corresponding to the information length of the parity check matrix H, the information length corresponding to the code length and the code rate, the information matrix being defined by a check matrix initial value table that shows the positions of the elements “1” of the information matrix at intervals of 360 columns. The check matrix initial value table is designed for digital broadcasting intended for portable terminals, for example. The present invention can be applied to cases where LDPC encoding and LDPC decoding are performed.
