<P>PROBLEM TO BE SOLVED: To provide an LDPC (Low Density Parity Check) code having satisfactory performance. Ž<P>SOLUTION: An encoding processing section 601 performs encoding by the LDPC code having, for example, an encoding length of 64,800 bits and an encoding rate of 3/5. The inspection matrix of the LDPC code is composed by arranging one element of an information matrix that indicates the position of the one element of the information matrix corresponding to information length according to the encode length and the encoding rate of the inspection matrix for each 360 rows and is decided by an inspection matrix initial value table at a period for each 360 rows in a row direction. The inspection matrix initial value table differs from that prescribed by the standard of DVB-S. 2. The present method can be applied to an encoder for LDPC encoding.
