Abstract
A DSV (Digital Sum Value) control system for use in conversion of a sequence of m-bit digital data codes into at least first and second sequences of n-bit digital modulation codes using a plurality of modulation tables under the DVD (Digital Video Disc) standards, for example. The DSV control system outputs a sequence of modulation codes produced by selecting, in time sequence, one of the codes of the first sequence or one of the codes of the second sequence according to a select signal SB. The select signal SB is provided based on a DSV control enable flag indicating that DSV control enable codes of the first and second sequences will appear at a following address and a select signal SA indicating which of the DSV control enable codes of the first and second sequences should be selected in order to optimize a DSV of the outputted sequence of modulation codes.
