I really didn't see the benefit of location presentation today, a couple of questions for anyone who knows the technicalities...
On location, what would the monitor in front of the anchor show? Sky News final output or just the location output? If its the channel feed, are they just receiving the picture through a satellite box on the same frequency we pick it up on?
Also how do they transmit the auto cue script from the Sky News Gallery to the prompter on location?
And same for presenter talkback, how do they get the audio feed with as little a delay as possible from the London gallery to wherever they are presenting from.
Can't answer all of those for you - but don't assume that when a presenter looks down at their feet that there's really a monitor there. They might just be taking their cues from the audio, and looking down is their cue for the director that they've finished talking.
I don't think it's likely that they'll transmit any special return vision, so if there really is a monitor there, it's most likely just off-air monitoring.
The clean feed to the presenter's earpiece could be transmitted on on a satellite link - it'll be low-bandwidth, so will have very little coding latency, but still the half a second for the satellite hop. Otherwise, they'll do it by mobile phone to a TBU in the truck - though that'll be lower quality for not much reduction in latency.
As for autocue? There's an app for that!
