Abstract (en)
[origin: WO0007361A2] In a one way broadcast digital video network, Internet HTML Web page data is formatted to fit within a standard MPEG-2 data packet structure, and multiplexed along with other MPEG-2 digital video signals for transport within a multiple channel digital video system. In particular, the headend server broadcasts a rotating carousel comprising an ensemble of Web pages in HTML format. The rotating carousel contains both broadcast Web pages and simulcast Web pages and a control map permitting the viewer to navigate among the HTML Web pages of the rotating carousel. In particular, the control map contains the locations of the HTML Web pages in the rotating carousel that correspond to broadcast Web pages. The control map further contains the locations of the HTML Web pages in the rotating carousel that correspond to simulcast Web pages. The control map is updated and rebroadcast whenever there is a change at the start, middle or end of a broadcast video program, thereby synchronizing the simulcast Web pages to the multiple channel broadcast digital video programs.
