Abstract
A method is described for efficiently delivering a presentation of web content comprised of a media, such as audio or video content, having defined time increments, together with one or more other content sources, such as images or events to be displayed on a monitor, synchronized so that the one ore more other images or events are displayed at predetermined time increments in the media presentation. Furthermore, the entire presentation is delivered in streaming fashion, so that the end user does not have to wait for the entirety of the content data to be downloaded before starting the presentation, but rather can start viewing and listening to the presentation after a relatively short delay period. The media data and the other content need not reside at a single server source. An authoring tool for creating such composite time-synchronous content automatically determines the necessary information for scheduling player requests to the servers. This information, together with the actual presentation content, is sent to a special player which can interpret the information and act according to its instructions.
