Abstract
A remote server generates a data stream that is broadcasted to a plurality of receivers. The broadcasted data stream includes a video track having a video data stream, a control track, and a plurality of ancillary data tracks including ancillary data. A specific template is assigned to each of the receivers. Each of the receivers renders a composite video image for display on a display device. Each of the composite video images includes the same video data stream, but each receiver uses its assigned template and selected ancillary data to render its own unique composite video image from the same video data stream.
