Patent number: 6151017Abstract: 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.Type: GrantFiled: September 12, 1996Date of Patent: November 21, 2000Assignee: Kabushiki Kaisha ToshibaInventors: Takashi Suzuoka, Takeshi Yokokawa, Toshiki Kizu, Mitsuru Kakimoto, Yasushi Kawakura, Takeshi Aikawa
