Gemini intercom links remote racing tracks for live production in Norway

The Trilogy Gemini distributed matrix intercom system has been linked by 10 km of fibre optic cable to provide the core intercom system for centralised production of multiple daily horse racing events for Mediatec Broadcast in Norway. Mediatec Broadcast, part of the NEP Worldwide Network, is now performing live production using the capabilities of Trilogy’s Gemini matrices and high speed link (HSL) to connect its master control room (MCR) and studio facilities. Trilogy’s HSL audio network is configured as a point-to-point connection, with failover to network for all traffic if the HSL-fibre link should fail.

Mediatec Broadcast AS Managing Director Lise Heidal said, “The key point is that we wanted centralised site operation but had to ensure full audio bandwidth and near zero latency. You can’t achieve that with standard IP links 10 kilometres apart, but you can when using Trilogy’s Gemini with HSL, which worked flawlessly.”

Gemini is Trilogy’s flagship intercom system, which is built on the concept of a de-centralised, scalable platform of 32 port matrices, each with IP connectivity. For harness racing production, information from comms links with cameras, reporters, commentators, and local control rooms at the 12 horse racing tracks spread around Norway are sent to Mediatec’s MCR in Oslo. There the audio is transferred to the Gemini intercom system and made available for crews at the MCR and studio.

IMG Productions, which produces the racing packages for broadcast, has a studio control room in Oslo that also uses a Gemini linked via fibre to a Gemini frame at Mediatec’s MCR, connected via a range of embedders/de-embedders for near-zero latency, full bandwidth, bi-directional communication.

During the summer of 2015, 10 out of 12 race tracks in Norway became operational with the Gemini system. The remaining two will come online in the coming months. Over the next five years it is estimated that around 2,500 productions will be done using Gemini matrix.

Mediatec Broadcast also has a large installation of seven Trilogy Mercury frames spread across Norway and Sweden to link studios, OB´s, MCR´s, broadcasters and other facilities. The system was recently upgraded to Trilogy’s new Gateway Version 5 software, which includes session initiation protocol (SIP) for audio over IP and new virtual panel applications. This enables Mercury to integrate with the latest Gemini system, which gives Mediatec’s comms system a combined availability of approximately 200 ports plus 150 IP channels.
