Abstract
Fast-forwarding and rewinding within a compressed video stream and a corresponding content stream of pages are disclosed. The compressed video stream is made up of intra frames, predictive frames, and bi-directional frames. The content stream has a number of trigger pages and/or script pages. An intra frame is skipped to within the video stream, and the trigger page closest to this frame is skipped to within the content stream. Alternatively, the script page closest to the frame that is not further ahead of it is skipped to within the content stream. This page is executed until the content stream is aligned with the video stream.
