Tieline is demonstrating two 3G voice-enabled software modules embedded into its Commander codec.
The modules are optional; one offers connectivity to HSDPA/UMTS/GSM frequency bands, and the other offers connection via CDMA EV-DO Revision A networks as well as the CDMA EV-DO Release 0 and IX networks.
“We are offering customers a truly integrated wireless broadcasting experience,” said General Manager Kevin Webb. “All you need is a broadband cellular provider and our codec makes the 3G broadband connection without the need of an actual phone. Turn it on and broadcast wirelessly.”
The company says an added benefit of the modules is improved audio quality with a doubling of the bit rate. Additionally, Tieline engineers found the modules to have a more robust signal strength than the option of plugging a cell phone into the codec.
Tieline also is demonstrating codecs that are compliant with the new audio-over-IP interoperability standards issued by the European Broadcast Union. The company says the scaling back, and in some cases shutdown, of ISDN networks in the United States and Europe is prompting the EBU to create operability standards that allow IP codecs from different manufacturers to communicate with each other.
