Studer spotlights new Call Management System at IBC

September 19, 2005

One of Studer's principal exhibits at the 2005 IBC will be its new Call Management System (CMS), developed to cover a wide range of communication-related applications in the broadcast environment. The CMS package includes a comprehensive telephone system, audio routing facilities, intercom and voice mailbox, on-air gaming and voting options, and sophisticated caller demographic analysis.

CMS can handle the full spectrum of telecommunications formats, up to and including the latest voice-over-IP technology. Entirely under straightforward software control, the system will manage and distribute calls to operators and reporters working in studios, newsrooms, offices and outside broadcast situations. It is fully scalable, handling simultaneous distribution of up to 240 channels using Ethernet connections. The system operates with full redundancy.

CMS offers standard communication protocols: H.323 for VoIP, G.711 softcodec for speech coding, G.722.2 and Speex softcodecs for wideband coding, and Ogg Vorbis for high-quality audio. Using wideband softcodec allows high-quality audio transmission into the mixing desk in the studio, using the same user-interface as for phone calls, avoiding expensive hardware solutions.

With unlimited number recognition in its database, the CMS represents a powerful tool in the broadcast house, capable of managing extensive demographic data for analysis, as well as providing enhanced opportunities for call-in competitions, voting and gaming. Not only does it provide virtually unlimited control over telephone traffic, it can also be used to handle signalling such as studio red-lights, signal lamps and other items of broadcast equipment that need to be controlled in tandem with communication systems.

Danmarks Radio adopts CMS

In Copenhagen, Danmarks Radio has confirmed a substantial order for a Studer CMS, which will be integrated with Studer OnAir 3000 digital consoles to give DR's new DR-Byen facility a comprehensive telecom management and distribution system, simultaneously operating up to 240 channels.

As the on-air date of April 2006 for DR's new flagship headquarters in DR-Byen draws nearer, technical experts started shopping around for an IP telephone system solution. The Studer CMS was the outstanding candidate, a choice based on the sound quality demonstrated in listening tests, and the added advantage of compatibility and integration with the OnAir 3000 audio mixing consoles which are standard throughout DR. According to Lars Lomborg, DR's general project manager for audio facilities, other systems were compromised by quite a high degree of delay, whereas the Studer CMS was much less affected.

DR's new system is capable of handling up to 240 lines simultaneously, accepting all standard formats from ISDN to the latest voice-over-IP technology. The DR system will use the G711 and the wideband G722 softcodec communications protocol between CMS server and client, and integrating CMS into the Studer OnAir 3000 consoles enables the fader screens on the console to display call information.
