All of the globe's networks are actually using one stream from the Olympic Broadcasting Services http://www.obs.tv/ http://www.obs.tv/ I found the making of videos they have on that page interesting. Basically the OBS are the ones doing the actual filming and broadcasting of all the Olympic events , and then all the broadcasters of the world rebroadcast that. They also provide all the onscreen graphics. So NBC could send down a tech crew and an uplink truck and we would still get full coverage of the Olympics minus all the color commentary.
