<p>A method and system for providing the creation of a visual summary of a video source during fast forward/rewind of the video can be created by using extracting frames either automatically or manually to create an initial visual summary. A series of weights may be assigned to the extracted frames, which are then filtered according to the relative weights to create a modified visual summary. The keyframe display rate is then adjusted according tot he fast forward/rewind speed, which can be either a standard speed or user selected speed, so as to display the keyframes while the video source is being fast forwarded/rewound. The keyframes may be substituted by selected images and audio, so that an advertiser can substitute an image of the product and a brief audio summary while the user is fast forwarding/rewinding past the commercial message.</p> |
