  • Patent number: 7546022
    Abstract: A method for reproducing a scene by a time shift is provided in which, by transferring a bookmark created by one viewer to an other viewer, the other viewer can also see a scene that the one viewer desires to see and the scene that the one viewer desires to see can be seen commonly together with the other viewer. To reproduce a recorded moving picture, a scene worthy of note is accessed by using the bookmark. When moving picture information is recorded, picture recording time of a specified screen region is stored in a manner that picture recording actual time of a desired scene is associated with the bookmark and, when reproduction is made, access is made to the scene based on time between picture recording actual time of the scene and of the specified picture screen region and image information of the specified picture screen.
