ABSTRACT OF THE DISCLOSURE 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 and eliminating from the error correction encoded data the dummy data and a redundant code of the error correction code formed by the dummy data so that the data transmission rate can be lowered.
