However, if an apology caption appeared the problem had nothing at all to
do with Emley (or any other transmitter)

It wasn't really an apology caption, it was the 'we are off the air'
caption for CBeebies.

Presumably after 7PM, with your TV/PVR tuned to BBC Four, it should be
consulting its local table of SIDs versus channels and extracting the BBC
Four streams from the multiplex. If it's displaying a CBeebies caption
instead, that almost suggests that the TV is picking out the Cbeebies
streams instead which time-share the same bandwidth but with different SIDs.

Bill said the caption was 'C Beebies Whoops we have a problem!'. That
would be what they would display if there was a problem during C Beebies
transmission hours. I'd guess that someone made a mistake by displaying
that rather than the BBC Four equivalent.
