DR is Denmark’s national broadcasting corporation that was founded in 1925 as a public service organization. Now DR operates four FM radio stations, 14 Digital Audio Broadcast (DAB) stations plus 13 web radio stations, two TV channels, and also operates a huge website that’s also accessible using a mobile phone. In other words, a large media player in the Denmark market
DR Byen requested formal proposals from interested companies to build a complete satellite communication platform, to be located on top of, and inside, one of the company’s new buildings comprising part of their new media facilities.
The plan was to present the following solution. Consider a suitable mix of rotatable and fixed antennas, as this would ensure complete commercial satellite coverage for this area of the world. Each antenna would be equipped with a feed to allow simultaneous reception of the two polarisations (H/V) in Ku-band and the low and high band frequency range. Each antenna would provide four L-band receive signals. The signals could be fed, via fibre optics, to a central receive system comprised of a powerful L-band matrix and an appropriate number of integrated receivers and decoders (IRDs). Such would allow the operator to receive all available TV channels at the same time, whether they were transmitted from an SNG van or from another broadcast organization.
Part of HILTRON’s concept included two multifocus antennas with as many as eight feeds, with each feed pointing to a different satellite. Such an antenna would provide as many as 32 L-band signals. The two multifocus antennas would have to be delivered and installed by a third party, but HILTRON could supply the entire radio frequency segment, including the fibre optic links
All antennas are designed for reception and transmission. This guarantees both tasks are met using the same platform - the reception of all necessary TV channels and the transmission of signals for distribution and contribution from headquarters.
The challenge & the delivery
HILTRON won this turnkey contract for the DR satellite platform partnering with BFE Siemens, Europe’s largest integrator for TV and radio studios. This contract is a huge success as well as a major milestone for Hiltron in terms of the company’s international references and reputation.
HILTRON was able to offer a solid, competitive solution, especially in regards to the need of installing all antennas on top of a high building with extremely limited crane access meeting the technical requirements and to comply with the overall DR Byen project management schedule.
The system supplied by HILTRON was comprised of the following major sub-systems:
The finished project
HILTRON implemented a fully versatile, future-proof, and extendable satellite platform based on state-of-the art equipment from leading manufacturers. The system is complete, from encoding and decoding of MPEG-2 signals, the entire RF technology as well as the complex antenna systems, all managed under a single, powerful M&C platform.
The M&C platform is the masterpiece of the system and allows the customer to carry out the following major tasks:
The satellite platform has been in operation for more than two years and no major problems have been reported so far. Plus, the system can be upgraded for additional, future satellite up- and downlinks without difficulty. DR Byen now operates a highly flexible satellite system, which is one crucial part of their large media center, making DR Byen one of the largest broadcasting companies in Europe. HILTRON was thrilled to play a major role in this accomplishment
