This year's Tour de France ended on Sunday (24th July), with its three week run covered by leading European broadcasters, including Germany's ZDF, which used a Riedel MediorNet network to connect digital satellite news gathering (DSNG) units with the central OB truck, writes Kevin Hilton. Host broadcast feeds for the Tour, which was won by Australian rider Cadel Evans, are supplied by France Televisions but broadcasters from around the world bring in facilities to tailor coverage to suit their own style and requirements. German public broadcasters ZDF and ARD sent eight OB vehicles, with DSNG crews out on the roads following the action. EVS digital non-linear player-recorders in the location units were linked to the main EVS SDTI (serial data transfer interface) back in the ZDF transmission scanner (pictured in the TV compound) using Riedel MediorNet. Matthias Kampen, technical director of ZDF, says this "drastically reduced" the amount of effort used to set up the cabling system. "Previously there needed to be an extra system for the EVS integration," he explains. "Now all signals run on just one link. In addition, MediorNet handles the distribution of the ZDF Ethernet network, which also made the whole set-up a lot faster and easier." Communications between the broadcast teams was over Riedel Artist intercom systems, comprising one 128 and two 32s, with three mainframes run by 32 control panels. Riedel was also involved in the race itself, with 50 NanoTalk radios used by teams, including Team RadioShack, to connect riders and their crews. www.riedel.net
