GPS antenna tracker for ski jumping in Oberstdorf

HDwireless Camera Solution with innovative AI tracking

HDwireless GPS Antenna Tracker Live Camera Helicopter Downlink

For the kick-off of the Four Hills Tournament in Oberstdorf on December 29 and 30, 2018, HDwireless was in action for the host broadcaster ZDF. The overall technical planning and the implementation of the host requirements were realized by the company “TopVision” under the leadership of Achim Jendges. On-site, HDwireless supported the OB-van service provider from Berlin with wireless camera systems and radio connections. HDwireless used its own development, the GPS antenna tracker, to receive live images from a camera helicopter. After a comprehensive hardware and software update last autumn, the established system offers many additional functions for the requirements of RF transmission. In addition to the “Traveled Path Recording” option already introduced, the latest version provides features such as “Auto GPS Location” and “KI Tracking Option”. The GPS antenna tracking system is connected autonomously with only one LEMO SMPTE fiber. Patrick Nussbaum describes the technology benefits as follows: “Here in Oberstdorf in the main focus is not on a range increase as in our other missions. With the tracking system, we can operate the RF components at the highest quality level through the optimized transmission. Thus, we reinforce our quality standards and can provide our customer, in this case TopVision, with a seamlessly integrated signal source.

CSi Conference 2018 again with HDwireless

Bidirectional video link for live transmission of surgeries

Every year at the end of June, the CSI Foundation invites to an international conference of cardiologists. For four days heart specialists, scientists and experts will exchange ideas in the Congress Center Messe Frankfurt. A special highlight is the simultaneous heart surgery in the Sankt Katharinen hospital, which is about ten kilometers away. For example, the congress participants can follow live-on surgeries in full HD resolution from the conference hall and simultaneously communicate with the surgeon in the OR via live video. This is possible through a bidirectional video radio link, which HDwireless sets up for the duration of the conference as early as the third year. For this purpose, the RF technicians installed transmitters and antennas for the point-to-point video transmission on the rooftops of the respective buildings. For the long signal paths within the building, the technicians used HDwireless RFiber. Using fiber optics, the signals could be routed over long distances to the target point, where they are reconverted to standard video signals. Thus, the transmission between the conference room and the operating room was carried out in combination with video transmission and optical fiber via HDwireless RFiber technology.

GPS antenna tracker with new features

HDwireless introduces second generation of a successful system

At the beginning of last year, HDwireless presented the prototype of a GPS-controlled antenna tracker. After successful test runs, a first series of trackers was produced. The system supported wireless camera transmissions with live images from vehicles at the receiver end or also the high-frequency radio transmission with relay aircraft over very long distances. Under the name HDwireless GPS Antenna Tracker, the exact and automated reception technology was also used in numerous projects to maximize the radio range. Due to the positive deployment experience, HDwireless is currently developing an enhanced version of the tracker with new features in hardware and software. In addition to the well-known precise spatial orientation, the RF technician will in future have access to all information about signal strength, alignment and hardware monitoring. For example, the GPS antenna tracker is often set apart on a working platform at very high altitudes for the best possible reception of the camera and data signals. In future, the program interface will display all relevant operating data graphically. The system also maps the current positions of the wireless camera systems in use via Google Earth. The “Traveled Path Recording” continuously records all GPS positions for analysis in ongoing production and displays them in the geographical map. Using Web Access, the production data is made available via the Internet for a transparent monitoring. The market launch of the new system will take place in late autumn 2018.

HDwireless broadcasts world premiere of MAN

Video transmission over 150 kilometers of autonomous driving trucks

On the 25th of June, MAN had the world premiere of truck platooning, the autonomous driving in convoy, on the A9 from Munich to Nuremberg with public traffic. For HDwireless it was an extensive project with cameras in moving trucks as well as on the ground and in the air along the freeway. All wireless camera signals were received and transmitted over the entire route at the positioned relay radio stations in Wolnzach and Hilpoltstein. This required a precise pre-planning. HDwireless Managing Director and Project Manager Patrick Nußbaum explains the successful RF concept and frequency management: “Our RF transmitter stations were located on two 70-meter-high cherry-pickers at calculated positions along the A9. They received the RF signals from the relay helicopter that was tracking the trucks”. The transmission of various wireless cameras in the trucks and an additional camera helicopter was possible without interruption. Also the RF communication was managed by HDwireless. Patrick Nußbaum: “We rent all the relevant RF components, so that the customer gets everything from one source. In this project, we deployed wireless camera systems, RF transmission technology, and team and production communication with Clear-Com HelixNet“. Via satellite uplink, the live images were transmitted to Neufahrn near Munich for an event at DB Schenker, the logistics service provider and MAN research partner. At the DB Schenker premises, the event guests were able to follow the world premiere of truck platooning on the A9.

Extensive Video Transmission of Semper Opera Ball

HDwireless Provides Wireless Camera Broadcasting for MDR in Dresden

“Magical Dresden – having a ball.” This was the motto of the 13th Semper Opera Ball. 2,500 guests inside the opera house and several thousand visitors on the Theater Square attended this social event which took place on January 26, 2018. An extensive stage program, prominent guests and many visitors to the ball made the event an unforgettable experience. The Central German Broadcasting Company, MDR, broadcast the ball featuring an action-packed program live on television. A team from HDwireless, commissioned by MDR, was on hand to provide extensive coverage using wireless cameras. Following intensive preliminary planning for the RF transmission in close cooperation with their client, the technicians devised an end-to-end solution for MDR involving connection to several OB trucks.

A few HDwireless GV INCAM-G handheld cameras and a Steadicam solution based on HDwireless GV INCAM-G Compact were used to transmit live images of the stage, the orchestra seats and the balconies to various antenna locations in the theater. Other wireless cameras transmitted images from the red carpet and the celebrations taking place in front of the opera house, which were then broadcast live in the ballroom and on a large video screen in the Theater Square, as well as being part of the MDR broadcast. HDwireless had stationed RF transmission and receiver technology in outside areas too. A further wireless camera was deployed to capture shots of the outdoor event and a big fireworks display in the sky above the opera house. Using a special point-to-point radio system set up at the Hausmannsturm to the south of the opera house, this wireless camera was able to provide bird’s-eye images of the event. Looking back on the impressive ball in Dresden featuring extensive wireless camera transmission, Patrick Nußbaum summarized the event as follows: “Every year, the Semper Opera Ball inspires both its guests and viewers by emitting a fantastic atmosphere – both in the opera house and on the Theater Square in front of it. The host of live images captured by our wireless cameras for the MDR TV program brought the atmosphere to life. This was possible thanks to precise planning in advance and well-coordinated teamwork with the customer on site”.
