Data processing device and method for selecting media segments on the basis of a score
First Claim
1. A data processing method, using a data processing apparatus including a processor, for processing media content comprised of a plurality of scenes, said method comprising the steps of:
- Inputting context description data into said data processing apparatus, said context description data including;
a data structure portion including a plurality of segments each for describing one of said plurality of scenes of media content, andan attribute portion that is attribute information of the media contents, said attribute portion including;
a context attribute having a value for describing a context of one of said segments, anda plurality of importance attributes each associated with one of said segments and having a value representing a degree of contextual importance of said corresponding one of said segments;
selecting, using said data processing apparatus, one or more of said plurality of segments based on at least one of said importance attributes; and
extracting, using said data processing apparatus, one or more scenes from said media content, wherein said extracted scenes are the scenes described by said one or more selected segments.

Abstract
A context of media content is represented by context description data having a hierarchical stratum where the lowest hierarchical layer is formed from an element representing a segment of media content which corresponds to a change between scenes of video data or a change in audible tones. A score relating to the context is appended, as an attribute, to individual elements in the lowest hierarchical layer. In a selection step of a data processing method, the context of the media content is expressed, and one or a plurality of scenes of the media content is or are selected on the basis of the score of the context description data.

9. A data processing method, using a data processing apparatus including a processor, for processing media content comprised of a plurality of scenes, said method comprising the steps of:
-
inputting context description data into said data processing apparatus, for describing said plurality of scenes, said context description data including; a hierarchically arranged data structure portion for describing the structure of said media content, said data structure portion including at least one section element and a plurality of segment elements as children of said at least one section element, each of said segment elements for describing a corresponding one of said plurality of scenes, and a hierarchically arranged attribute portion including; a plurality of viewpoint elements each including at least one keyword for representing a particular viewpoint of said media content, one or more scores as a child for each of said plurality of viewpoints, each of said scores being an attribute associated with one or more of said segment elements for representing a degree of contextual importance of said parent viewpoint with respect to the scenes corresponding to said one or more segment elements, wherein portions of said attribute portion are linked to corresponding portions of said data structure portion; selecting, using said data processing apparatus, one or more of said plurality of segment elements according to a desired one or more of said viewpoints based upon said scores; and extracting, using said data processing apparatus, one or more scenes from said media content, wherein said extracted scenes are the scenes described by said one or more selected segment elements. - View Dependent Claims (10, 12, 13, 14, 15)

16. A data processing method, using a data processing apparatus including a processor, for performing the method comprising the steps of:
-
Inputting, into said data processing apparatus, previously generated context description data that describes a plurality of scenes of the media contents of one or more media files, said context description data including; a plurality of segment elements each for describing one of said plurality of scenes, a plurality of viewpoints each being an attribute associated with one or more of said segment elements and each including at least one keyword for further describing the contents of the scenes described by the associated one or more of said segment elements, and a plurality of scores, each being an attribute associated with one of said segment elements representing a degree of contextual importance of one of said viewpoints that is associated with said one of said segment elements with respect to the scene described by said one of said segment elements; selecting, using said data processing apparatus, one or more of said segment elements based on an analysis of said viewpoints and/or said scores; and extracting, using said data processing apparatus, one or more scenes from said media content, wherein said extracted scenes are the scenes described by said one or more selected segment elements. - View Dependent Claims (17, 18, 19, 20)
