Client Appl Filtering Application regarding segments filtering
Summary This component generates summary description which consists of the segments that
have user's preferred viewpoints. As an output, this component generates
content description based on Summarization. A summary is generated dynamically
so that a user's preferred time duration and preferred viewpoints
(PreferredSummaryTheme in user description side) which are described in
user description(SummaryPreferences) given as a query parameter may be suited.
Strong Points User adaptation scalability of summary description generation based on
the combination of viewpoint(s) and time duration which user required.
This summary generator(segment filtering) application can be used as a preprocessor
for the Summarization DS as well as scalable multimedia distribution which is
adapted to various kind of user preferences.
Limitations The input XML file must have two or more Segment descriptions with MediaTime
and PointOfView descriptions.
The query XML file must be a MPEG-7 user description which has at least one or more
PreferredSummaryTheme description(s) with or without SummaryDuration description.
Known Problems NONE
