- the definition of the value for the key that is, the text data corresponding to the keyword (eg, strikeout, home run, Ichiro, Jiro, 2004/04/01, 2004/04/02, etc.)
- XML Since XML has strict tag rules, using XML simplifies processor processing. In addition, by using XML, the data is structured, making it easy to search for data. Furthermore, since XML is required not to depend on a specific language or environment, an attribute called xmklang and a “language identification code” to describe the value of this attribute are prepared, such as English and Japanese. Designed to handle multiple languages, it can flexibly handle multiple languages.
- the processing of the controller 51 in particular, the data search processing becomes easy, and it becomes possible to flexibly cope with multiple languages.
- a plurality of search keys can be set for a scene of one section specified by the IN point and the OUT point, and hierarchical navigation can be performed.
- hierarchical navigation can be performed.
- the degree of freedom for scene search is increased.
- one section specified by the IN point and the OUT point may be shorter than, for example, a cell or play item that has been conventionally defined as a playable section ( In other words, cells and play item strengths).
- Multiple sections specified by IN and OUT points For example, it is possible to easily generate a digest of a scene desired by the user based on this section.
- the scene additional information may include, for each scene, a thumbnail image that represents the contents of the scene or that corresponds to the video at the IN point.
- the thumbnail corresponding to the key value can be easily displayed on the GUI screen, and the search key can be easily selected by the user.
