ABSTRACT:
Allowing the ability to specify a general frame format and to automatically recognize similar frames at later points in time. A user initially selects the type of frame by watching a particular program such as the weather portion of a newscast and selects the desired frame using a hand-held control unit similar to the present hand-held control units for VCRs or television sets. When the frame appears on the television set, the user presses a button on the hand-held control unit, and the apparatus stores the frame that is presently being displayed. The apparatus then analyzes the stored frame to determine a set of recognition parameters. Those parameters are used to recognize similar frames in subsequent broadcast segments and to store one of those recognized frames for each broadcast segment. The user also specifies a time period during which the system will search for the specified frame. Further, the audio portion of a program segment is stored as long as frames are being recognized in that segment.
