Hannover, Germany (March 19, 2012)—German TV production provider has TVN upgraded its TVN-‹2HD OB truck with Riedel MediorNet and two Riedel Artist Digital Matrix Intercom mainframes.
As part of the change, the connections for set and remote operation of the 20-camera HD/3-D truck were switched to Riedel MediorNet. In addition, the entire audio system was completely rebuilt. The audio router is now a Lawo mc256 digital audio router; the intercom system is based on two Riedel Artist Digital Matrix Intercom mainframes (Artist 128 & Artist 32) with about 50 Artist 1000 control panels.
At the heart of the TVN-‹2HD installation are five MediorNet mainframes that act as pre-routers for up to 32 HD-SDI signals connecting to eight stage boxes that are used on the OB truck's productions.
Those stage boxes are also based on MediorNet and provide bi-directional transport over a single fiber link of up to four 3G, eight HD or 30 SD video signals as well as audio, intercom, or control data such as TCP/IP or serial RS232/422 data. Since MediorNet is based on a real-time network with an arbitrary number of different topologies, signals can be routed not only between the stagebox and the OB truck, but also between individual stage boxes or from a single stagebox to multiple stage boxes.
"The connection of the stage boxes via MediorNet enabled us to transport a large number of different signals such as video, audio and GPIOs. This significantly reduces the amount of time that we need for setting up. Plus, it also makes our system a lot more flexible because we can easily change the routings of a stagebox without any problems," said Wolfgang Peiss, head of sales at TVN mobile production.
The Lawo audio router and the Artist intercom system are connected to the MediorNet network via MADI, while the Miranda NVision 8208 router is connected via coax video cables.
