The headend server broadcasts a rotating carousel comprising an ensemble of Web pages in HTML format containing both broadcast Web pages and simulcast Web pages and a control map permitting the viewer to navigate among the HTML Web pages. The control map containing the locations of the HTML Web pages in the rotating carousel that correspond to broadcast Web pages and the locations of the HTML Web pages that correspond to broadcast Web pages.
