Abstract
A format to be used with the MPEG-4 standard alters the way video content is displayed on a screen based on whether the content is played in a normal playback mode or a fast playback mode by “watermarking” different or additional visual content onto the original video data stream. Metadata is included in the format to instruct a server to change the video display during fast playback by, for example, adding advertising information, closed captioning, scene summaries, help data, or station identification to the original image, either in a separate section of the screen or superimposed on the original image.
