  • Patent number: 8947459
    Abstract: A contents playback apparatus and the like are provided which allow a user to promptly designate a desired portion when displaying a part of a content in an expanded manner, and are thus excellent in operability. A contents playback apparatus includes an associating unit and a playback unit. The associating unit generates association information for a plurality of characteristic portions contained in a content by referring to priority orders of the respective characteristic portions relative to each other, the association information associating each of the characteristic portions individually with a predetermined operation key of an input device included in the apparatus in accordance with the priority orders. The playback unit plays back, in response to detecting an operation of an operation key during display of the content, the characteristic portion corresponding to the operation key in an expanded display mode, in accordance with the association information.

  • Patent number: 8295823
    Abstract: A mobile communication system includes: a mobile terminal; plural base stations each of which can conduct communication with the mobile terminal; and a cooperative server that can conduct communication with the base station. The base station detects entrance and exit of the mobile terminal into and from an area covered by the base station and notifies the cooperative server of a detection result. The cooperative server acquires positional information on the mobile terminal from the notification, and stores a residence history of the mobile terminal based on the positional information and a script indicating a rule of a mode setting designated in each mobile terminal in history storing means. The cooperative server activates the script to determine a mode changing command in each mobile terminal based on the residence history and transmits the mode changing command to the base station.
