Well, after the 'anorak heartbeat raising surge' moment of actually seeing something of interest during the studio 1B downtime, instead of watching some bored scene shifters wandering around the place, I noticed watching both the under camera monitor feed from NBC London and the autocue, that Brian was in complete sync with it.
I believe it's how they ran the Today show during the Olympic games from Stratford, with autocue and directing/VM'ing from New York with everything being firbered under the Atlantic - despite galleries in the IBC about 2 minutes walk away from the temporary studio.
One Today Show staffer told me that during Rio every single camera was backhauled via fiber to New York where the show was vision mixed. What was also impressive was during the political conventions about 20 cameras were uplinked via satellite to NYC where it was mixed and everything was in perfect sync. I am not sure how the other networks were handled but NBC’s feed was usually ahead of the others.
I believe that was also the case in Beijing in 2008. All cameras fibred back to the US where the show was cut as normal. Doing it over fibre is non-trivial, but avoids most latency issues.
A number of broadcasters did their main Olympic presentation this way in 2012 - with control rooms cutting between remote camera feeds in control rooms back home. Some also did remote camera control (i.e. black level, exposure, colour balance shading etc.) at base. Over fibre you can get full tallies, data etc. and if you want to use prompt (though Olympic sport shows probably don't need or use it) you can do that remotely. Latency is just a couple of frames at most if you do it right.
Doing the same via satellite is trickier - as you will inevitably have higher latencies - and that can give you issues with delayed talkback, implementing tallies (if that is done) etc. It's impressive to get all cameras in sync perfectly - I guess you have to run the same encoders and decoders at both ends, probably in low latency mode.
