Multi-Media Scanning Control

      A methodology is described that permits a user to automatically
scan and play portions of multi-media files.

      Searching for information in multi-media files is a tedious and
time-consuming task since there are no adequate searching algorithms
for multi-media files (e.g., video and audio files).  This
methodology allows a user to automatically scan small portions of a
multi-media file to help pinpoint the exact information the user is
interested in finding.  This methodology works much like a scan
function found in some stereo systems that permit users to sample a
few seconds of each radio station on the dial until the desired radio
station is found.

      This methodology allows a user to scan multi-media files as a
way of helping the user pinpoint a particular piece of information
within the file.  When the user starts the scanning function, a small
piece of the beginning of the file is played (this "piece" is
referred to as a "sample" of the file).  After a few seconds, another
small sample that is found further into the file is played.  This
goes on automatically until the user finds a sample of interest and
manually stops the scan, positioning the current location of the file
to the point the scan was stopped.  In other words, as soon as the
scan is stopped, the user can resume playing the multi-media file at
the point where the last scan was terminated.  The scan will also
automatically stop when the multi-media file has been completely
played out.  One feature of this article that makes it unique is that
the user can set the amount of time each sample is played for (e.g.,
5 seconds, 10 seconds, 1 minute, etc.) and also the amount of
information that is skipped before the next sample is played (e.g., 5
seconds of information skipped, 10 seconds of information skipped,
etc.).  As the multi-media file is played, the user can additionally
mark, or note, the current file location that corresponds to the
sample that is being played.  This is equivalent to putting
bookmarkers at different pages in a book for later reference.  Once
the scan has ended, the user can obtain a list of all marks made
during the scan.  Upon selecting a mark from the list, the
multi-media file will automatically begin play at the location
specified by the mark.  A user creates these "Multi-Media Markers" by
either pressing a specified key, articulating a voice command, or
other forms of user interface.  The Scanning Control will interpret
these actions and set the markers at the appropriate locations in the
file.

      The interface between the user and this scan function is done
thru an End User Interface control as shown in the figure.

      This interface permits the user to start the scan by pressing
the SCAN button on the control and stop the scan by pressing the
button once again (after the scan has been started).  The amount of
time to skip after every sample and the amount of time...
