On the occasion of the „SWR-TV Family Fest 2016“ on September 4, 2016 spectators and passengers experienced an extraordinary view of the Koblenz cable car. One cabin rode above the ropeway all day long as a floating live TV studio across the Rhine. SWR commentator Anna Lena Dörr and YouTuber Phil Laude entertained meanwhile with good humored commentaries, chatting with passengers and invited guests while floating back and forth between ground and hill stations. In order to achieve this the cabin had been equipped with the fitting camera and transmission technology. A very special challenge for this unusual studio was that cable connections cannot be installed in moving cable cars. Helmut Kremer, technical support manager of SWR, commented: “Our concept demanded a permanently moving set. This required an uninterrupted and stable implementation of a radio connection for video and audio signals. This is why we turned to HDwireless who had already quite frequently developed some tricky wireless solutions”. During the planning stages HDwireless computed and coordinated all aspects of this radio transmission, frequency allotments from the authorities included. This also included close coordination with the manufacturer of the Aereal Ropeways, Messrs. Doppelmayr Seilbahnen of Austria. The planned antenna fittings for the ropeways, as well as the technical equipment inside the cable cars were closely monitored and tested for their safety while in operation and moving. SWR asked for three cameras inside the cabin whose signals would guarantee transmission from there without interruption. HDwireless installed antennas within the ropeways and also on the 40ft high mast of their own RF1 production unit that would provide stable transmission. Patrick Nußbaum, CEO HDwireless, explains: “All signals of this live broadcast were wireless. Our client had to depend 100% on our broadcasting quality. He received the flawless signals at the transfer point via our glass fiber transmission technique. This production from the cabin is a very good example for individual and successful realization of an extraordinary broadcasting concept.”

HDwireless provides live transmission of Formula 1

Complex wireless transmission for stable video and communications signals

Within the scope of the Hungarian Grand Prix at the Hungaroring in Budapest on July 24, 2016 HDwireless transmitted live TV from the actual Formula 1 event. “HDwireless was commissioned by the Host Broadcaster as service provider. It was our task to transmit live video signals of the Formula 1 spectacle directly to the director from the locations paddock, pit lane, and starting grid. By doing this, we very closely cooperated with Imre Sereg, the production manager on location”, Patrick Nussbaum, Manager of HDwireless comments.

By way of wireless camera technology we transmitted flexible and lively camera perspectives to the receiving unit RF1 of HDwireless. This HF-production vehicle is equipped with an antenna mast of 12meters in height. By means of RFiber – an HDwireless glass fiber product – the HF-signal was sent from the antenna position to the signal processing equipment inside the vehicle. From there it was fed to a receiver, then decoded and submitted to the Host Broadcaster’s OB-truck.

Aside from the wireless camera transmission HDwireless fulfilled several radio services. For example: the program signal was relayed to the expert commentator’s monitor.  Furthermore, HDwireless supplied important audio signals like directing communication – the IFB/N-1-signal to the team radio and the field reporter – for a smooth procedure.

For stable transmission from and to the various locations the HDwireless technicians installed their own antenna network connecting all receiving points via ASI-transport stream, and thus assuring permanent and flawless transmission.

HDwireless with live-video via mobile radio from the operating room

Cardiologists follow surgery in real-time while in a conference hall

The projection in the conference hall shows live open-heart surgery. The audience watches the operation attentively on a screen, and they listen to the surgeon’s comments. Viewers in the hall also converse directly with the physician. The occasion was the international CSI conference at the Congress Center of the Frankfurt Trade Fair from June 22 to June 25, 2016. The organizer had asked HDwireless to install bi-directional transmission paths (radio links) between operating theater and the congress center so that cardiologists from all over the world would be able to watch several surgeries live and of dependable high quality.
For the transmission in full HD resolution of HD-SDI in 1080/50i over a distance of approximately 10 km the best answer proved to be radio waves in a frequency range of 2 to 3 GHz. In agreement with the Hessian Federal Network Agency HDwireless assumed responsibility for the frequency planning. To increase the transmission safety frequency filters were installed, which guaranteed flawless live transmission of the surgery demonstration for the academic faculty members. For faultless real-time communication between the Congress Center and the operating room HDwireless applied its own point-to-point transmission technology. Patrick Nussbaum comments: “For wireless transmission we embedded the sound into the transmission signal, only to separate it after decoding. We used our HDwireless-fiberglass network on both sides of the radio links. Our client took over complete and latency free signals.”

This way the cardiologists with their high analytic requirements were able to follow various surgeries live and synchronized in highest uncompressed quality.

HDwireless with Citynet in Dortmund

Wireless Camera for TV-Reporting

On May 21, 2016 at 8 PM the kick-off whistle sounded for the DFB Final game between FC Bayern and Borussia Dortmund at the Berlin Olympia Stadium.

That was also the start of the stand-by time for the HDwireless crew. On behalf of WDR TV six HDwireless technicians had installed a socalled „Citynet“ in the inner city limits of Dortmund in order to facilitate consistent transmission of wireless camera signals.

The BVB-trucks motorcade was enabled to transmit live signals from two HD cameras. Preceding this, some detailed planning was necessary to position the relays for signal reception from the BVB-Truck and transmit them to the central receiving station, as well as the coordination of the frequency ranges. „A network of relay stations was needed to receive the signals from the BVB truck and in turn transmit them to the central receiving station. From there, the customer would receive the result via fiber network solutions“ Patrick Nußbaum, Manager HDwireless GmbH, explains.

The Citynet was additionally installed for reporter and directing communication by way of digital radio waves. “Aside from the video signals  in cooperation with CS com solutions with a “Digital Trunking System” we transmitted an entire bundle of the much needed signals for the directing and the crosslinked relay stations – is exceptionally well suited for region-wide and at the same time flawless wireless transmissions”, comments Patrick Nußbaum.

HDwireless @ Wings for Life World Run Schweiz 2016

Fixed-wing aircraft as a means of innovative relay station for HD video signals

On May 8th 2016, HDwireless broke new ground at the “World Run – Wings for Life” event in Olten, Switzerland.

In order to cover the marathon via wireless camera live signals were transmitted from several motorcycles to a specially equipped plane circling over the race circuit. This craft had been rigged to serve as receiving and transmitting unit, and its live pictures reached the local “WirelessVideoVillage” via a tall signal mast. “On the plane we received the various signals – interference minimized by diversity-demodulators – from where we forwarded them per RF stream to the central receiving station. With this combination of relay plane and wireless technology we are the first providers in the broadcasting market of Germany” says company manager Patrick Nussbaum. In order to deliver high quality live-camera shots of the marathon custom-made motorcycles were prepared in cooperation with TVtek prior to the project’s start. Due to the TÜV (Technical Supervisory Association) approved seat modifications with foot rests for a cameraman sitting in reverse on the backseat it was possible to film the runners from the advance motorcycle.

Each bike was equipped with its own transmitting technology from HDwireless. Not only video signals but also audio signals, communication, and the GPS positions were transmitted. The aircraft´s pilot was briefed to optimize its course at any given time. This was made possible via the exact position coordinates the camera-equipped motorbike convoy kept transmitting. This way the 30m high GPS-controlled antenna array at the central reception point was enabled to always receive flawless signals. Patrick Nussbaum explains: “The diversity ASI chaining-technique covered an area of 160square km.”

The signals received via the aerial array reached the mobile production unit RF1 via fiber optical transmission, an HDwireless vehicle used as receiving point for wireless-camera signals. The directors and editing communications were offered as an additional project function mutually handled by CS com solution and HDwireless. In closing Patrick Nussbaum summarizes: “The technical concept, the transmission relays, and the reception technology were developed and produced by HDwireless.

We are very satisfied with the flawless and consistent transmission of the World Run for the entire duration and distance of the event”.
