Your reference says that the signal went from ISS to the Johnson Space Centre, to the cloud, and then via geostationary satellite to a truck at Las Vegas. ISS is at 400 km, the Earth's radius is 6,300 km so the maximum distance from ISS to the Johnson Space Centre is of the order of 6,000 km. Geostationary orbit is at 35,000 km, so the signal had to travel about 76,000km, the speed of light is just under 300,000 km/s which gives a time of travel is about a quarter of a second. And a round trip time of half a second (the time from a question being asked and the questioner hearing the astronauts response). The actual video coding happens in real time, so most of the delay will have been to do with Amazon's servers.

the first segment had lag-no lag-lag?
If there was an eleven second delay (so stated by them), how was it possible for Fischer to respond/react immediately--- even after acting as though he couldn't hear instantly?
Nothing in OP gave an impression these events happened together whatsoever.

I know that live broadcasts in Britain have an 11 second delay.
Nothing to do with tech problems, but a safety measure because the singer Morrissey said on live TV he hoped that Thatcher would die.
Or so I've heard...
Don't know what it's got to do with this little gem of stupidy the freak calls a thread, though.

Originally posted by shavixmirIf there's a delay of any kind, is it as elastic as these dorks show, or is it static, as one would assume?

I phoned them regularly the next time we spoke... bloody annoying.

If there's a lag, how did those conversations take place as recorded?

You know, save it up for 20 seconds, so that everything from then on doesn't lag.
I don't even know if that's possible. But I presume it is.

Here's the one with the painful duet.

But really: since you don't watch videos, what difference does it make anyway?

Originally posted by shavixmirPrior to the interview, its also possible that the astronauts got a copy of the questions they were going to be asked, so they could anticipate what was coming.

The fact that the male apparently smiled and made woo in sync with the folk on earth may have more to do with the fact that he was reacting to what was being said the way a teacher would who was out to prompt a class to respond a certain way. In the actual live event audience members who may have been primed to respond and woo to emphasis the point may just have triggered a little early.
If you think that concept strange, think of recording a sitcom in front of live studio audience and then reinforcing that applause and laughter with a laugh track later to better trigger your target audience so that they know when to laugh. Its all Pavlovian and nothing to do with space fakery but more to do with neuro linguistic programming.

act as though there is a lag, then act as though there isn't a lag.
Interesting suggestion.
Doesn't explain the real-time conversations and exchanges in all three examples... and certainly cannot explain singing a duet.

No.
The host says his spiel, they wait (according to him) eleven seconds, she responds with their position, crowd reacts to her, he reacts at the same time.
There was nothing else for him to react to, except what she is saying, and in agreement with the audience.

Originally posted by FreakyKBHAnd you know this how? All I see is a reaction that is simultaneous with the crowd. I don't see any evidence that he is reacting to the crowd and not something that happened 11 seconds ago. We have only your word on that.
Yeah...
No.

As for other videos, the lag would be different for different links, just as the lag is different on different phone calls. As has already been explained to you, there is no actual technical reason why there must be noticeable lag at all.
And worst of all, what did you think it proves? Why would they fake a lag?

Originally posted by FreakyKBHThe duet was done using a direct link with a signal lag in the milliseconds. There really isn't anything to explain.
So...
act as though there is a lag, then act as though there isn't a lag.
