| 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 |
| Parameters | InputXML = Input file name of MPEG-7 content description with PointOfView [default: xmlinputfile.xml] At least, Segment, MediaTime and PointOfView descriptions are needed. OutputXML = Output file name of MPEG-7 content description based on Summarization. [default: PointOfViewFiltered.xml] |
