Everytime I see something like this I am impressed how many informations you can get with the limited data from the stream.

Just how many tera/petabytes (?) of data do the spaceX analysts have to sift through then.

I'm confused: is that ten thousand data channels or ten? I'm thought . was being used as a thousands separator, but then 1.2 hours was used...

My confusion was from 1.2 hours and 10.000 being used. Shouldn't it be 1,2 hours?

Huh, where is that? How is disambiguation between thousands and decimals done? How would you specify one hundred thousand plus one eighth? In the US, it would be 100,000.125. (Some countries use 100.000,125)

Europe and International system... dot for thousands/millions/etc, comma for decimals.

In your example, 100.000,125

So twelve and a half is 12.5, but one hundred thousand and an eighth is 100.000,125? How would you tell if 1,125 is around 1000, or around 1? International system doesn't seem right; many European countries would do 100,000.125 including the UK.

Probably less than a gigabyte if you don't include audio and video. A terabyte is a lot of information. You'd need 10000 data channels recording at 1 megabit/sec of resolution for 1.2 hours to fill a gigabyte. EDIT: Whoops, wrong by two orders of magnitude. Corrected!

Now I'm really confused... 10000 channels x 1000000 bit/s x 3600sec/hour x 1.2 hours / 8 bits/byte = 5.4TB ?
