Atlanta, GA (May 26, 2010)-Germany's DELEC announced installation of its Oratis commentary system in several OB trucks owned by TV Productioncenter Zurich AG (TPC) in Switzerland.
To meet the needs of multi-language sports productions, five TPC OB trucks have been equipped with one Oratis matrix frame and six commentary terminals each; more installations will follow during the year. Up to three commentators can share a single unit. Thus, a dual-commentator environment supplemented by a roving reporter loses its complexity and will become the norm.
First applications of the new system include international broadcasting from the Spengler Cup ice hockey tournament in Davos and a number of skiing and football productions--a total of 10 matches or competitions, on average, every weekend.
The Oratis commentary system is based on a matrix frame installed in the OB vehicle, which acts as a central audio router. The commentators use an Oratis commentary terminal connected over a Gigabit Ethernet link to a commentary card in the matrix frame. This approach enables the OB truck's audio network to be extended easily via fiber-optic cable up to the commentary booth, making it possible to monitor and mix any audio signal locally at the commentary position.
Up to 12 commentary terminals can be driven by one matrix frame. In addition, the system can be tightly integrated with the NEXUS audio routers in the truck using MADI lines, making the Oratis matrix frame a real audio hub for all the commentators. Integrating an extra commentator into this set-up requires hardly any expenditure of additional effort. Large productions in particular, with multiple commentators, as is usual in multilingual Switzerland, benefit most notably from this approach.
Integration with the intercom system prevalent in Switzerland was also a consideration; this has been achieved in an ingenious way that enables the intercom to share the commentary terminal's microphone, headphones and cabling structure.
