A multimedia player parses a presentation script for delivering to a user a presentation that is comprised of a video, slides and tangential content. Each slide is associated to part of the tangential content and to a specific playback time or frame within the video. The presentation script describes the relationships among the video, the tangential content and the slides. The multimedia player has a presentation control unit which provides the graphical user interface for displaying the video and the slides, and for allowing the user to manipulate the presentation. The player allows the user to select one of the slides to access the tangential content which has been associated to the slide according to the presentation script. In another embodiment, a presentation authoring tool allows a user to generate a presentation script describing the relationships among a video, a set of slides, and a set of tangential content.
