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
Sometimes when the picture is lost we see a testcard with streambox on it. I guess this is the device that does the video encoding.
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?
