Dusseldorf, Germany (May 27, 2011)--Riedel Communications' fiber-based MediorNet system distributed video, audio and communications signals at the recent Eurovision Song Contest.
Riedel installed a system comprising of MediorNet, RockNet, Artist and Performer components, turning the Dusseldorf Arena, a former football stadium, into a 15,000-sq.-m. TV broadcast studio. To provide the broadcast infrastructure and the signal distribution backbone Riedel installed a system that distributed 70 HD/SD-SDI video signals, 1,200 audio signals and 734 communications ports. A total of 70 MediorNet mainframes were used to integrate the various positions and departments into a single system, including the TV compound, commentator positions and the press center.
MediorNet was responsible for transporting the broadcast signals to the OB trucks and distributing the video signals within the arena, for example, to the monitors on various visitor floors, the video walls, as well as the green room and the commentator booths. "MediorNet's network approach allowed us to keep full flexibility regarding the signal distribution and allowed us to monitor the complete installation," said Simon Korzen, project director for the ESC at Riedel Communications.
Around 1,200 audio signals were transported via MediorNet and RockNet during the event. To distribute the wireless microphone signals from the splitter world to the FOH, the monitor mix or the amp racks, a RockNet installation with connections to the MediorNet system was used.
The digital and analog outputs of the Sennheiser wireless receivers were used independently to feed an analog and a digital RockNet module for hardware redundancy. RockNet expansion cards for digital Yamaha mixing consoles integrated the Yamaha PM5D consoles at the FOH and the monitor consoles into the audio network. The connections to amp racks in the ceiling and to the OB trucks in the TV compound were realized via MediorNet and RockNet links.
