摘要： The present invention relates to a modulation apparatus and method for more accurately determining a value of a control bit to be inserted into a data sequence, and to a DSV-control-bit generating method. A 1-7 PP data conversion unit 52 supplies modulation-delimiter information including information regarding delimiters of modulation of a data sequence based on a conversion table based on Table 3 to a modulation-delimiter detecting unit 81, and supplies to a valid-delimiter detecting unit 81 a DSV-segment-delimiter. signal including information regarding a delimiter position of a DSV segment of the data sequence including the DSV control bit inserted. The modulation-delimiter detecting unit 81 detects modulation-delimiter positions based on the modulation-delimiter information supplied thereto, and supplies a modulation-delimiter signal to the valid-delimiter detecting unit 82. The valid-delimiter detecting unit 82, based on the DSV-segment-delimiter signal supplied thereto, detects a valid-delimiter position for controlling timing for determining a DSV control bit of the relevant DSV segment from the modulation-delimiter positions represented by the modulation-delimiter signal supplied thereto.
