Live feed from across the world - how does that work?

[guapoharry]

This isn't a quote, just trying to prevent that stupid web link embedding the SG website tries to force on you... It does it with you tube also...

I just watched a feed that was live from Reunion Island. (east of Madagascar in the Indian Ocean) It was about that girl who was trying to sail nonstop around the world.

How does that work? A hop to Europe and then a hop over the Atlantic to the USA or what?

I believe it was 10 AM there and here it is 10 PM. That is seriously across the world...

Curious.

Vaguely off topic, yet significantly relevant, what is the embedding to which you refer?

Or better yet, I think I suddenly understand. If you "Go advanced", and uncheck one/all of the three 'automatically do stuff' options.. Maybe that's what you're looking for.

They might be using the S-Band freqs, for SAT-Phone links for one signal's relay to other satellitel's......

Second options is HF radio, which skips off the F-2 layer, but the that's like's the weather propigation.

Most ship's use 16 MHz band's but I could be wrong on that....

Maybe it's just this simple:

Perhaps an Earth station on Reunion Island (56ºE) is pointed at a satellite that can be seen from say... France.

Then, a teleport in France (2ºE, perhaps) receives that feed and retransmits it to a satellite somewhere over the Atlantic.

Then, a teleport in the US (81ºW, perhaps) receives that feed from the satellite over the Atlantic and retransmits it to a satellite over say,,, Nebraska (about 100ºW)

Then affliates can see the feed from the satellite over the US.

Maybe that's too complicated. Perhaps there is a satellite that has LOS from both Reunion Island and someplace in North America...

However, they could use transoceanic / terrestrial fiber optic cable and transmit the feed as a data stream data for a portion of that distance too. Would that be less costly, or not?

OK USDownlink, you are correct. That's what I was looking for. However, it doesn't always show up under Miscellaneous Options as follows:

Show your signature
Automatically parse links in text
Automatically retrieve titles from external links
Disable smilies in text

I'm just trying to do a normal link like this...

What I don't care for is the deal when you post a link from certrain websites. It retrieves the picture from them and forces that linked to page's title into the field as well. (Wikipedia or You Tube for example) [ame="http://en.wikipedia.org/wiki/Communications_satellite"]Communications satellite - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Wideband_Global_SATCOM_Satellite.jpg" class="image"><img alt="" src="http://upload.wikimedia.org/wikipedia/en/thumb/d/d7/Wideband_Global_SATCOM_Satellite.jpg/250px-Wideband_Global_SATCOM_Satellite.jpg"@@AMEPARAM@@en/thumb/d/d7/Wideband_Global_SATCOM_Satellite.jpg/250px-Wideband_Global_SATCOM_Satellite.jpg[/ame]

When you go to the bottom of a page (like this one) and select Go Advanced, (as opposed to Post Quick Reply) you only get four selections under Miscellaneous Options.

When you go to a post and select Quote, to do a Quote, it adds a fifth option under Miscellaneous Options....

Automatically embed media (requires automatic parsing of links in text to be on).

But, when you Preview Post once, that "Automatically embed media" option goes away...:rant:

Guess you only get one chance....

Ah, Reunion Island. Made a brief port call there in '79. I still remember how much it looked like Hawaii from the sea. Very French.

Well, TBN uses the bouncing ball technique --- Satellite to satellite. Paul Sr used to like to watch the signal after it did a full circle there was a ten to fifteen second delay. Now there does seem to be more fibre optic links.

As an uplink engineer who has done similar multi hop links - you pretty much nailed it. Loads of fun as long as some uplink in the path doesn't decide to re-encode the signal instead of passing on the ASI signal.
