Method for Manipulating Digitized Analog Signals

      A method is described which allows convenient manipulation of
digitized analog signals.

      Currently, applications are used to manipulate portions within
a digitized analog recording.  Such applications provide means for
navigating around within the presentation for selecting a stream of
the presentation with cut and paste operations.  A method is needed
for manipulating a digitized analog signal in an independent manner
from the type of presentation -- video, audio.  A method is needed
for manipulating a presentation's individual frames or sets of
frames, thereby permitting edits of the most atomic level of an
analog presentation.

      With reference to Fig. 1, an icon will be present on a desktop
which may appear like that which is shown.  The icon should display
an image indicating an analog signal or the like.  This will
instantly let the user know analog function is associated with the
icon.  A user is able to drag a digitized analog file to the icon,
hereinafter called an Analog Manipulation Icon.  Upon dragging a file
to the icon, a panel will be displayed showing attributes currently
associated with the file.  If the file is not of a digitized analog
type, this article will provide an indication to the user.  Fig. 2
shows a resulting attribute panel when a video image file has been
detected from the drag operation.  The user may change modifiable
attributes which are present thereby affecting the state of the video
image presentation.  If no changes are made at this time to
modifiable attributes or changes are made to desired values, then the
user may select OK to continue.  Fig. 3 shows the two types of icons
which may result when selecting OK on the attribute panel -- a video
icon and a sound icon.  All presentations are mapped into one of
these two icons.  Once the file is iconized, it remains on the
desktop for subsequent manipulation.  The object is the user's handle
to the file dragged to the Analog Manipulation Icon.  The associated
file name is present with the icon.  Opening the icon (e.g., mouse
double click) presents the digitized analog as a series of individual
frames.  Fig. 4 shows an example of this.  The user is able to select
individual frames which...
