London region digital switchover (Phase 1 and 2, 4 and 18 April 2012)

The analogue terrestrial television was switched off in the London region between 4 and 18 April 2012.
0:00 - 1:20 - BBC Two, 4th April 2012 (note the ghostly 1970s BBC2 symbol that appears after the switch-off, which is actually a trailer for 'The 70s' series, a weak signal that continues to break through for some reason).
1:21 - 2:17 - Channel 4, 18th April 2012 (before the ETP-1 testcard appears on Channel 4 - the first thing to seen on the channel back in 1982)
2:18 - 2:48 - BBC One
2:49 - 3:37 - Channel 4
3:38 - 4:09 - ITV. This actually switched off some ten minutes before Crystal Palace, in the middle of a programme just after a commercial break. (Channel 5 also switched off some time before it did at Croydon).
