Riedel goes skiing for ORF

18 February 2010

TVN Production utilised an extensive Riedel MediorNet installation for the broadcast of the women’s Super G World Cup in Haus im Ennstal for the Austrian broadcast network ORF.

Despite the extreme temperatures of minus 20 degrees Celsius the Riedel fibre technology enabled a successful event. A total of four MediorNet mainframes were used at the start and finish lines. The frames distributed the individual video signals between the remote video control on the mountain and the TVN OB van that was used for the ORF broadcast. MediorNet routed ten HD and three SD video signals from the video control to the OB van; four HD signals were routed back to the video control. Integrated CWDM multiplexing enabled the transport of all signals on only one duplex fibre connection.

“MediorNet enabled a flexible installation of our systems. With the large distances that had to be bridged at this World Cup, the use of copper cabling would have been a lot more expensive and complex. Despite the rough weather conditions MediorNet worked perfectly,” said Felix Rumpf of TVN.

In addition, the MediorNet installation provided a clock master for the remote video control. While the OB truck utilised a tri-level synchronisation MediorNet converted the synchronisation into a Blackbust signal for the video control.

Furthermore, 22 audio channels for camera communication and ambience microphones were routed between the two positions. Ten GPI/Os were used for the camera’s red light control.
