Could they piggy-back on the ITV playout facility in Leeds, maybe?
The last I had heard from friends at ITV that Red Bee/ITV were considering moving northern playout from Leeds to their new facility at MediaCityUK. The idea being that they would not only save the cost of running two facilities, they could also save on connectivity costs as the MCUK facility is conveniently in the same building as ITV Granada.
Not sure if they're still considering a move, it was definitely only an idea when I heard it, but if they are it would be reasonable to assume that Leeds might not be around for much longer.
It's a very quick turnaround. Editing it is done sometimes as close as up until an hour before broadcast at times and they have to deliver it by bike to get through the traffic.
I would be very surprised if they're still doing physical delivery by bike, although that may have once been the case. If it's edited too close to broadcast to send the show via FTP, usually they now require a circuit to be booked between the post production facility and Red Bee, and for the show to be played over the circuit to them as if it was a live show.
