Abstract: A method for displaying an enhanced multimedia presentation including personalized supplementary audio, video, and graphic content selectable by a user and rendered by a receiving device, comprises the steps of: communicating a multimedia presentation file to the receiving device, the multimedia presentation file comprising base multimedia presentation content and, frame-synchronized information including starting frame timing identifier, ending frame timing identifier, starting frame spatial coordinates, ending frame spatial coordinates, and motion vector specifications for describing frame-accurate location, motion and timing of the personalized supplementary audio, video, and graphic content, the frame-synchronized information indicating one or more free areas of the multimedia presentation absent significant base multimedia content; extracting the frame-synchronized information from the multimedia presentation file; retrieving the personalized supplementary content from the receiving device; decoding the personalized supplementary content at a time sufficiently in advance of the starting frame timing identifier; and the receiving device selecting an indicated free area and initiating display of one or more items of the personalized supplementary content at frame-accurate times between the starting frame timing identifier and ending frame timing identifier at the frame coordinates in accordance with the frame-synchronized information.

Abstract: The present invention is a method for the coordination and display of graphics or play out of audio or video in conjunction with a multimedia presentation. Graphics objects such as text or sprites, which may be animated, are displayed by the viewer's equipment, which is typically an advanced television or set-top box, which plays the video and audio. Graphics objects are displayed at locations which are complementary to the locations of objects in the video. Similarly, audio or video clips, stored in the set-top box, or embedded in the stream can be played at appropriate times and screen locations in the presentation called video and audio "holes". Data describing these "holes", and other control information is embedded in the video stream and extracted by the viewer's STB for use in coordinating tandem play.
