Abstract
A data processing device and a data processing method capable of improving the resistance to error of data. An LDPC encoder performs encoding using an LDPC code having a code length of 4320 bits and a coded rate of one of four types including ½, 7/12, ⅔, ¾. A parity check matrix H of the LDPC code is configured by arranging elements of 1's of an information matrix, which are determined based on a parity check matrix initial value table of the parity check matrix H representing positions of elements of 1's of the information matrix corresponding to an information length according to the code length and the coded rate for every 72 columns, in a column direction at a period of 72 columns. The parity check matrix initial value table, for example, is used for digital broadcasting for mobile terminals.
