Abstract: A “hold” feature on a user operated remote control allows a currently displayed track or view to be maintained while a video presentation is being played. As a user is watching a presentation that uses multiple camera views shown one-at-a-time as in a standard edited cut (i.e., “director's cut”) of a movie, the user can press a button when the user sees a camera view or scene of particular interest. Thereafter, the track associated with the camera view or scene that was showing when the hold button was pressed will continue to be played in place of the presentation. To return to the edited cut the user depresses the hold button again. The held track will continue to play until the user decides to resume presentation of the edited program or until the held track ends. Upon ending, the program track is resumed. While holding a track the user is free to select other available tracks in addition to jumping back to the program track at any time.

Abstract: In performing stereoscopic view, a shift information memory stores, as a number of pixel lengths, an offset indicating how far in a right direction or a left direction to move coordinates of pixels to realize stereoscopic view. When realizing stereoscopic view, a plane shift engine moves the coordinates of image data in a graphics plane in the right direction or the left direction by the number of pixel lengths indicated by the offset. When a scale of video data targeted for stereoscopic view is changed by a basic graphics plane, a shift distance of pixel coordinates by the plane shift engine is based on a number of pixel lengths obtained by multiplying the offset by a changed scaling factor in the horizontal direction.
