Zurich, Switzerland - Jun 29, 2009 - Barix has completed an installation for the Hessischer Rundfunk (HR, Hessian Broadcast) broadcasting service in Frankfurt. HR uses a system comprised of several Barix audio-over-IP components for permanent monitoring of up to three FM programs at the transmitter site in nearby Friedberg.

The broadcast signal is fed directly from the transmitter into a Barix Instreamer 100 audio encoder. The signal is then streamed back over a VPN link to the broadcasting center for confidence monitoring. In case of modulation loss, a backup feed over IP will be activated using Barix devices. An Instreamer unit at the broadcasting center will then stream the station audio over the VPN connection to the transmitter site. HR is Germany's first public radio service known to use Barix components in a broadcast mission-critical environment for confidence checking and program monitoring.

In addition to routing audio over IP and outputting error-messages, the Barix components in the HR installation are also used to control RDS and ancillary data. Other hr projects use Barix devices such as Barionet IP controllers and temperature sensors for various control and monitoring tasks.
