[i.h]

WC and NTL made great fanfare about being able to squeeze telephony (I'd guess that's within an E1) and data channels into their system - would there have been room for that *and* the VBI stuff?

But Westcountry's own Ancillary teletext and of course subtitles would have been carried via that route.

But as our resident expert says, its carried in a data channel separate to the video and would need to be inserted later. I'm sure it was technically possible for HTV to do the plumbing to put ORACLE through that, but they would have no reason to do so. As you said yourself to me - "the customer gets what they want".

Presumably that is what they did for regional teletext, PDC, subtitles etc (though this could also be delivered in another way I guess), but not for the main Teletext Ltd feed
