BBC Wales continuity is still from Belfast for their opt-out. How would this work? Are the running order and programmes stored somewhere centrally on a server which NI can just use or is there more to it? How is Belfast CA actually switched to air in Wales?
(BTW I find it very impressive that this can actually happen at all!)
Yes the running order (schedules) are stored centrally, as are programme files, which allows what you're witnessing tonight. And yes, there's more to it than that... It takes a good bit of work to get it all up and running, and to have someone in the seat running it.
As mentioned earlier in the thread, all BBC services are feed to a centralised coding centre before being distributed to Sky, Freeview, etc... so it's a case of that centre pulling out the feed from BBC Cardiff and patching in a feed from BBC Belfast.
