<p>An editing system and delivery system synchronizes the transmission of interactive elements with a video signal, such that the interactive components may supplement information provided in the video signal at predefined periods. The interactive elements are transmitted in relation to the video such that the interactive elements will arrive in time to display the components concurrently with a portion of the video presentation. The interactive elements may be transmitted within a video signal to a viewer. The viewer is configured to display the interactive elements in response to a signal from the delivery system. An editing system is disclosed that may define a programming track for interactive elements that may be associated with one or more audio and video tracks. The editing system schedules transmission and appearance of the elements. A graphical user interface of the editing system may display a time in a presentation timeline when the interactive elements appear and the duration which the interactive elements are displayed. Graphical user interface representations of the interactive elements are translated into commands including file transfer instructions to be executed on a playback system. The playback system may transmit information element data within a video signal to a viewer.</p> |
