  • Patent number: 7103604
    Abstract: A scheme for constructing a database in a user system, which can automatically store those portions of the structured documents which contain important contents without exerting a burden on the user is disclosed. A structured document provided by a server device is obtained according to a document request made by the user system, where each structured document has a structure represented by tags in each structured document. Then, at least one important portion is automatically extracted from the structured document by utilizing the structure of the structured document according to prescribed extraction criteria specified in advance, and the extracted important portion is stored into the database, while the obtained structured document is transferred to the user system.

  • Patent number: 6151017
    Abstract: A method and a system for displaying multimedia data including video data. A display of video data and related information are controlled according to a movement of a pointing selection marker, a type of related information, or a distribution of pointing selection possible regions over frames of video data. Linked related information can be displayed in synchronization with a progress of a display of the video data. Information indicating a presence/absence of pointing selection possible region for currently displayed video data can also be displayed. A useful information can be obtained by collecting a statistical information on the desired positions specified by the user's pointing selection inputs. Each frame of video data can be partitioned and related information can be provided in correspondence to partitioned parts of each frame.
