  • Patent number: 7796857
    Abstract: A video playback apparatus includes: video data inputting unit; a ranking data inputting/generating unit that inputs or generates ranking data where scenes in video data are ranked according to importance; a playback scene determination parameter inputting unit that inputs parameters when determining scenes to be played back according to importance; a playback scene determining unit that determines playback scenes based on ranking data and playback scene determination parameters; and a display unit that displays playback scenes. A viewing time of video data that the user desires and a maximum time width of each playback scene are inputted to the playback scene determination parameter inputting unit, and the playback scene determining unit cuts scenes so that the playback time of the playback scenes fits the maximum time width, and determines the playback scenes so that the sum of the playback time of the playback scenes fits within the viewing time.

  • Publication number: 20080138034
    Abstract: In the present apparatus, keywords contained in a selected movie contents data are indicated, for example, for selection by a user so that the user can view a desirable scene designated by the user. The apparatus includes, for example, a keyword displaying unit for displaying, on plural windows, plural keywords corresponding to a movie contents data, a selection input unit for receiving a selection input of a first keyword selected from the plural keywords displayed by the keyword displaying unit, and a scene playback unit for playing back one or more scenes corresponding to the selected first keyword.

  • Publication number: 20060233522
    Abstract: A video processing technique which enables users to effectively watch highlight scenes while listening to audio part thereof in a short period of time is disclosed. Upon input of video data, highlight scene data describing therein a highlight scene(s) in the video data is input or generated. Then, based this highlight scene data, determine a default playback parameter. Control is provided to reproduce the highlight scene(s) of the video data in a way such that when inputting a parameter for determination of a playback scene(s), this input playback parameter is used while giving thereto higher priority than the default playback parameter.
