<p>Distributed synchronous program superimposition may be achieved by a first entity receiving a digital video data stream comprising time-stamped moving picture video data, determining superimposition data for use in superimposing a first one or more digital images on a second one or more digital images in the stream, and sending the stream and the superimposition data for remote superimposing of the first one or more digital images on the second one or more digital images in the stream. A second entity remote from the first entity receives the stream, the superimposition data, and the first one or more digital images, and superimposes the first one or more digital images on the second one or more digital images in the stream to create a superimposed image stream, where the superimposing is based at least in part on the superimposition data.</p> |
