A context of media content is represented by hierarchical context description data for describing a plurality of segments. Each of the segments represents a scene of media content. Scores that are attribute information of the media content, and for representing a degree of importance of each of the plurality of segments based on a context of the media content, is input and/or appended, as an attribute, to a number of the hierarchical layers of the description data. One of the plurality of segments can then be selected based upon the scores.
