An information processing apparatus includes a generating unit for
generating ClipMark formed by a mark specifying a characteristic picture
extracted from an input AV stream, as management information for
supervising the AV stream, and for generating PlayListMark, formed by
marks pointing to a picture optionally specified by a user, from a
reproduction domain corresponding to the PlayList defining the
combination of preset domains in the AV stream, and a recording unit for
recording the ClipMark and PlayListMark as respective independent tables
on a recording medium. With the information processing apparatus, it is
possible to access a desired location of an AV stream promptly and
reliably.
