Jog Shuttle Graphical Construct

      A graphical construct that could be used like a jog shuttle to
control the display of video in a multimedia application is
described.

      A jog shuttle is a type of control that is used on remote
controllers of some top of the line VCRs.  The jog shuttle consists
of a rotatable disk with a small indentation (making it easier to
spin the disk), surrounded by a rotatable ring.  Rotating the disk
clockwise/counter-clockwise causes the video to advance/back up frame
by frame.  Rotating the outer ring clockwise/counter-clockwise causes
the video to proceed increasingly faster in the forward/backward
direction.  The outer ring's position is shown by a small arrow or
notch.  Also, the outer ring has a spring inside it which causes the
ring to return to the center position when released (video then
returns to play mode).  This combination of function allows anywhere
from very fine to very coarse control of video speed, making the
scanning of video much more efficient.  In upcoming years, jog
shuttles will probably become a more common feature on VCR remote
controllers.

      To allow such control of video in a multi-media PC environment,
a graphical construct implementation would be the most useful (not
requiring any additional hardware).  Two ways in which a graphical
construct could be implemented are as follows.

      The use of a scroll bar as a jog shuttle.  The arrows of a
scroll bar could be clicked on with a mouse, causing the video to
advance or back up frame by frame.  The slider would act like the jog
shuttle's outer ring, increasing/decreasing the speed of the video...
