ABSTRACT:
A data converting apparatus inserts DC control bits in an input data series to generate a redundant data series. This apparatus determines the value of the DC control bits in such a way as to minimize the DC component of an output code series which is obtained by subjecting the redundant data series to code conversion. The apparatus performs code conversion after inserting the determined DC control bits.
