Video Tabs for Accessing Multimedia Data

      This article describes a method for editing and positioning
video data (although the principles are equally applicable to
animation and similar data types).

      Because a video clip cannot be viewed simultaneously in its
entirety, it is very difficult to locate specific frames or scenes in
the video, and to return to those locations accurately.  It is also
difficult to precisely select a range of frames for editing; this
must be done by trial and error since the endpoint frames are not
visible during the selection operation.

      This invention requires that the video be represented as a
stack of frames, arranged like a large deck of cards, or like a book
viewed from an angle.  The MIT Media Lab has developed a system for
viewing video in this manner.

      This invention adds to that representation the ability to
"slide out" one or more of the frames, which will then act as tabs in
the stack of frames.  This is somewhat analogous to partially lifting
out a slide from a 35 mm slide projector tray.  The video frame
remains a part of the overall video object.  See the illustration for
a rough idea of its appearance.

      Clicking on these tabs will position the video "cursor" to that
location.  This positioning will be the new start position when the
video is played, or it may be used as an endpoint in a selection
operation (when selecting a frame or a range of frames for editing).
