Telewest launched it’s Active Digital TV service in 1999 and was built on the same foundation that Cable & Wireless used for their digital TV service.
These screenshots were originally hosted on Digitalspy and were captured by a forum member, but the links to them were broken in an update, and were no longer directly accessible. From the looks of it they were captured using the RF output, so they are not indicative of the quality available at the time.
Now & Next bar, very similar in practice to Sky Digital
The main home screen
The main TV Guide, called ‘At-A-Glance’, this shows TV listings for the next three days
Pressing i calls up a description of the program
This isn’t true video on demand, at this point only NVOD was supported. the customer selects a convenient time slot showing to view the movie or event

Main settings area
You can set the reminder notification warning before the program starts. Its worth noting that cable had implemented this before Sky Digital,
Here you can change from RGB to Composite, and set the box to output widescreen or standard. Letterbox options are also available.
The early implementation of interactive was done in a separate Liberate browser, that had to be loaded separately. this meant that red button functionality was not yet possible in this build, since the Liberate environment was not yet running full time.
The main interactive menu, very similar to the ntl interactive portal
List of all entertainment interactive services, which are customised websites that are designed for use on an embedded set-top-box.
Interactive is delivered using the internal broadband cable modem built into the set top box, a phoneline is not required and the service is always on
Nearly all of the content and service are built using HTML3, which makes it easy to develop and host service, although there are some differences and restrictions comparted to a desktop class website.
A navigation bar can be used to browse around the service, and to exit back to the tv channel you were watching
An email service was built into the service, and was tied into the blueyonder email service.
