Engineering:Test Channel 6

From HandWiki

Test Channel 6 was an experimental television channel jointly operated by the BBC, ITV, Channel 4 and Five. These networks recruited a few hundred volunteer homes for an experimental technical trial to see how high-definition television could work on the Freeview digital service.

The channel was only available in London and required a prototype Freeview set-top-box. Transmissions ceased[when?] once the short-term trial finished after a few months.
