Saif Al Islam Gadaffi Captured

Gadaffi found??? Inside a cluster of buildings inside the Tripoli compound. Lyse Doucet in the vicinity.

Speculation rife.

Could be a false alarm though. If it is Gadaffi, its another coup for Sky News who have been rolling with it since Reuters first reported around an hour or so ago that rebels had surrounded buildings where they thought he was. BBC News have seemingly been ignoring the story, or only spending a short amount of time reading out the wire reports, probably holding back on focusing more on it until there is more information. Even so, with 24 hour news, you snooze, you lose.

Special edition of BBC World News at 4pm LON time, Peter Dobbie and Lucy Hockings in London.

James Reynolds also in the studio - dressed like Elvis Costello, or similar! LOL.

Stuart Ramsay live outside the compound, well across the street it seems. Dramatic footage as rebels flee car as shooting happens

Pretty dramatic stuff on Sky now - Stuart Ramsay forced off air due to a gun battle. He is currently taking to Kay on the phone. The camera has been left on, still sending live pictures but in a locked position.

Don't you think, fodg, that Stuart Ramsay sounds very much like the former ITN Correspondent, Desmond Hammill?

compelling viewing, but stuart sounds like he's stuck in quite an exposed position.

Tim Gatt on Twitter says the pictures have been put on a slight delay. I guess this is incase anything bad happens.

Kay Burley just confirmed that too. The pictures lost the live bug about ten minutes ago.

How are the pictures arriving in London? Could someone else pick them up if they had a satellite dish pointed in the right direction or would they be encrypted? Stuart Ramsey is back on the phone now, I wonder why he had to go before, Kay Burley says it was to 'speak to London'.

There was a report somewhere on what they are using, I'm sure someone more technical can say.

I can only presume his bosses wanted to check he was ok.

He has lowered his voice to a whisper almost. Incredibly compelling television.

Sky coverage excellent. Kay is also very good at this type of thing too.

They're probably using BGAN or similar - it'll be a laptop-sized satellite antenna, a bit like this.
It'll give them a ~500kbps data pipe, maybe even via the internet from Inmarsat to Sky - and they'll then use a video codec of some sort to squeeze the output of their (possibly HD) camera down the very narrow IP pipe.

The high quality pictures will be using a more traditional uplink setup, using a flyaway dish. Anyone would be able to pick those up if they knew where to look, albeit with a professional satellite receiver.
