The News Channel countdown usually ends at :59:58 to make sure BBC One can get a clean opt in when they switched to the studio at the TOTH.
Before the pandemic the countdown before the Ten was not played by Studio E (Studio A which carried Outside Source at 9pm instead) so they didn’t need to leave the countdown at :59:58 because BBC One had already got a clean opt in.
Thank you, Frances. Why does the studio that the countdown is run from make a difference to how easy it is for the network to opt in?
As far as I know, network runs the One, Six and Ten bulletins via a specific feed, which normally carries the Studio E output without the DOG and flipper, it’s different from the News Channel distribution feed.
In the pre-COVID era, 5pm was BBC News at Five from Studio C and 9pm was Outside Source from Studio A gallery, so the countdown before the Six and the Ten could be played by those studios, the News Channel then switched to Studio E as the clock hit the top of the hour, at the same time BBC One joined the bulletin feed. Here’s the timeline:
17:00:00 Studio C goes on air with BBC News at Five
17:56:xx Studio C runs Weather, trailers & countdown
18:00:00 BBC News at Six begins via Studio E, meanwhile BBC One opt in the bulletin feed
21:00:00 Studio A goes on air with Outside Source
21:56:xx Studio A runs Weather, trailers & countdown
22:00:00 BBC News at Ten begins via Studio E, meanwhile BBC One opt in the bulletin feed
As deejay
mentioned before, the special staff arrangement under COVID has caused a side effect, that means the countdowns before the Six and Ten have to be played by Studio E. So they need to cut from the countdown to the presenter before BBC One joining the studio. The timeline is now:
17:00:00 Studio E runs BBC News
17:56:xx Studio E runs Weather, trailers & countdown
17:59:58 Studio E runs BBC News at Six
18:00:00 BBC One opt in the bulletin feed
21:00:00 Studio C goes on air with BBC News with Katty and Christian
21:56:xx Studio C runs Weather (sometimes trailers)
21:58:30 Studio E goes on air with the countdown
21:59:58 Studio E runs BBC News at Ten
22:00:00 BBC One opt in the bulletin feed
I don’t know why do they run the countdown via E instead of C but I
guess it’s for a World News America opt in for BBC World News. That could be spotted at the first two seconds of the Ten on the News Channel:
In a nutshell, the countdown normally ends two seconds before the scheduled time to make sure BBC One (and the other simulcast channels like BBC Two and World) can get a clean opt in, otherwise 1/2/World might crash into the last few frames of the countdown. Here’s an example.
