Bahrain – BSI’s roving cameras cover the pit lane, and Martin Brundle’s walkabouts and interviews. The mobile monitor provides off-air pictures and a video prompt. that the race was stopped for a period, due to poor visibility and water on the track. The equipment includes some “specials” which BSI has developed for live motor racing. There are six radio camera systems with two return vision systems, all in High Definition, with receivers and a fibre-based infrastructure. This had multiple antennas which enabled the roving cameras to cover everything happening around the pit lanes and paddock garages. The transmitters are attached to Panasonic camcorders with full camera control and full tally and a Remote Control Panel which BSI has provided for the F1 TM series. Everything is operating on the 7GHz frequency. The return video is a portable monitor, working with the fibre network with a remote transmitter powered down the hybrid fibre. The RF cameras operate within a cellular environment with multiple receivers. Any event of this size creates a challenging environment for RF engineers to manage the signals. In this case, BSI is providing 4 simultaneous feeds for Sky Sports, and all four cameras are operating in one UHF channel – this was a pre- requisite due to the scarcity of wireless spectrum available at the venues. A large amount of cable is needed to connect the pit lanes and paddocks to the OB village. It’s a hybrid fibre solution that powers the remote receive infrastructure down the cable to the TV compound. Technical Director Tony Valentino comments, “The key to success lies in preparation and planning, which was all done in advance to ensure that everything worked right first time. A lot of thought went into getting it right, so that we could just turn up, plug in and switch on and have all of our cameras fully operational right through each race.” Commenting for Sky Sports, Darren Long said: “The RF environments in and around the F1 TM venues are some of the most difficult to deal with so when Sky Sports were looking for a RF supplier, we needed one who had a proven track record of working in these environments, and a team that had the expertise to deliver in any difficult condition. BSI have delivered 100% of the package we asked for and Sky Sports have been very happy at the service we’ve received.” The author, Dave Remnant is Business Development Director for BSI www.broadcastsportsinc.com TV-BAY MAGAZINE | 67 TV-BAY067JUL12.indd 67 05/07/2012 22:31
