  • Publication number: 20220157042
    Abstract: A control unit (11) of a control apparatus (10) determines a “usage dividing position” from among a plurality of dividing position candidates based on the number of the substream data series for which the tracking continuity is lost when the “stream data series to be divided” is divided at each of the plurality of the “dividing position candidates” that differ from one another. The dividing unit (12) divides the “stream data series to be divided” at the “usage diving position” determined by the control unit (11) to thereby form the “divided data series”.
