PURPOSE: To elevate error correcting capacity, and to constitute a device of a small number of components, by providing each specified encoding adaptable means and encoding means on a device for encoding digital information.
CONSTITUTION: On a device 610 for encoding digital information having two- dimensional bit arrangement of k1×k2 bits, an encoding adaptable means 612 for generating the bit arrangement of k2×(b) bits by dividing K1 bits in the first direction to each (b) bits is provided. Also, the first encoding means 613 for encoding to n2×(b) bits by adding m2=n2-k2 number of check symbols, by k2×(b) bits consisting of K2 bits in the second direction and said (b) bits, and the second encoding means 621W62n for encoding k1 bits in the first direction to n1 bits by adding a check bit of m1=n1Wk1 bits are incorporated.
