Abstract
A data transmission and reception apparatus and method capable of selecting either of two modes having the same sampling frequency in which the bit numbers of one data unit are either m or n (which are integral numbers and m>n), while using the same error correction encoder and decoder for the two modes, by inserting m-n bits of dummy data bits into the n-bit data so as to handle it as m-bit data during the processes of error correction encoding and decoding.
