HDwireless RF1 Used for “Dirndl! Fertig! Los!”

Premiere for HDwireless RF Production Vehicle in Munich

HDwireless RF1 acts as the interface between wireless camera systems and OB trucks for broadcast productions. All signals coming from the entire radio system are received in the truck and then transferred to the broadcaster following signal conversion and decoding. Recently, the video technology in the production vehicle has been developed further to encompass the universal 3G-SDI standard and so that it is suitable for 4k settings. The RF structure has also been expanded by multiple RF distribution units and “RF over fiber” solutions. This means that up to 16 wireless camera systems, including camera control, can be processed in parallel by means of the signal and process structure. Using this state-of-the-art equipment, the successful first use of the newly equipped RF production vehicle took place in Munich on September 16, 2017, for the MDR production Dirndl! Fertig! Los!

On set were a HDwireless ULC steadicam, three handheld cameras and a remote camera positioned far away on the tower of St. Paul’s Church, which is located several kilometers away. All wireless camera systems for the live production from Circus Krone with the presenter Florian Silbereisen were equipped with Grass Valley LDX camera heads and RF transmitters. Every part of the Circus Krone arena and its interior surfaces were covered by a central antenna structure. A relay radio station, which was located on the roof of the Bayerischer Rundfunk (Bavarian Broadcasting Company) building, was required for the camera on the church tower due to the large distance. As well as transmitting the camera signals, HDwireless was responsible for team communication, which was also put into effect by means of the transmitting and receiving systems of RF1. Patrick Nußbaum, CEO of HDwireless, had the following to say about the event: “RF1 fully meets our expectations. The production vehicle is an excellent all-in-one solution for high-frequency radio transmissions of all sizes. We are delighted to have received positive feedback about RF1 and our solutions from our customers.”
