CODING DEVICE AND TRANSMITTER

CODING DEVICE AND TRANSMITTER

In a coding device (20), a first coding unit (21) generates a parity of an RS code by coding, based on the RS code, each first data sequence existing in a direction different from a row direction of input data, and generates coded data by attaching the parity of the RS code to each first data sequen...

description In a coding device (20), a first coding unit (21) generates a parity of an RS code by coding, based on the RS code, each first data sequence existing in a direction different from a row direction of input data, and generates coded data by attaching the parity of the RS code to each first data sequence, thereby consequently expanding a matrix. A second coding unit (22) generates a parity of a BCH code and a parity of an LDPC code by coding, based on the BCH code and the LDPC code, each second data sequence existing in a row direction of the coded data, and generates a plurality of DVB-S2 frames (13) including, per DVB-S2 frame (13), one data sequence existing in the row direction of the coded data, the corresponding parity of the BCH code, and the corresponding parity of the LDPC code.
