Frank, WGAT uses VBI and high powered RAID5 servers at the headend.SEAC is a company working with WGAT for channel hyperlinking. internettelephony.com WorldGate's TV On-Line, on the other hand, uses a server located at a cable company's headend to deliver Internet access over the vertical blanking interval. Most consumers without PCs probably won't be downloading the kind of information that requires a full 6 MHz channel and cable modem speeds, Lee said. But they will appreciate speeds up to three times faster than telephone modems, allowing the cable TV company to conserve channels. Hiram

From readind the ATVEF site, and docs, it appears that they are using VBI, but that they have developed a HTML format for their purposes. The set-top device is expected to then have a cache for the pages and other information, to be displayed at the appropriate time. > I suppose that if they are using bit mapped payloads, and VBI > optimization, then they could very easily deploy their systems over > cable operators' facilities that are currently (and simultaneously) > supporting either ATHM or RR. True or false? Yes ... it appears that this stuff will work ... even over broadcast television signals. It looks like the communications is only one way and that the channel simply sends the pages, to be cached, all the time. The user is then just "interactive" with their set-top box ... not all the way upstream.

It appears that these guys are doing the same type of thing ... I'm trying to find more on the two-way/interactive questions ... > Regards, Frank Coluccio Scott C. Lemon
