How The Tour de France Reaches Your TV

After twenty five years with the BBC I know a little about staging outside broadcasts.

I was chatting with some friends about how the coverage of the Tour de France works when I realised that I didn't understand all the technical links employed in this huge, mobile event.

I claim no credit for the graphic opposite.  

I found the answers to my questions - and whole lot more info than I understand - on a very good Australian website called Cycling Tips.
