A method for providing a user-adaptive digest stream provides a digest
stream of a multimedia stream having a user-desired length and reflecting
the user's preference/non-preference. The method for providing a
user-adaptive multi-level digest stream can dynamically provide the
user-adaptive digest stream according to user preference information. The
method can include searching user preference information having user
preference/non-preference level by categories for a multimedia stream,
and reconstructing a multi-level digest stream information on a
multimedia stream as a multi-level digest stream information according to
the user preference information, using both the searched user preference
information and a content-based data of a multimedia stream. Thereby, it
is possible to quickly, accurately and conveniently provide a multi-level
digest stream corresponding to the user's preference without inputting an
additional query condition.
