Data Processing Device And Data Processing Method

Abstract: The present invention relates to a data processing device and a data processing method capable of improving data error resilience. In a case where LDPC codes having a code length of 4320 bits are mapped to sixteen signal points, a demultiplexer performs replacement assigning b0 to y0, b1 to y4, b2 to y1, b3 to y6, b4 to y2, b5 to y5, b6 to y3 and b7 to y7 for LDPC codes with a code rate of 1/2, and assigning b0 to y0, b1 to y4, b2 to y5, b3 to y2, b4 to y1, b5 to y6, b6 to y3 and b7 to y7 for LDPC codes with code rates of 7/12, 2/3 and 3/4, where (#i+1)-th bits from the most significant bits of 4×2-bit sign bits and of 4×2-bit symbol bits of two successive symbols are represented by bits b#i and y#i, respectively. The present invention can be applied, for example, to a transmission system transmitting LDPC codes.
