Perth, Western Australia, 11th December 2007 -
Leading codec manufacturer Tieline Technology has joined the Audio-via-IP Experts Group as a technology provider advising on the interoperability of audio codecs when broadcasting over IP. Tieline joined other Group members Orban CRL, Mayah Communications and AETA, and will collaborate on interoperability when developing new audio over IP enhancements.
"This is a terrific step forward for broadcasters," said Tieline's International Marketing Manager Darren Levy. "This move reinforces our belief that codec manufacturers need to collaborate, to make it easier for broadcasters to evolve from existing circuit-switched infrastructure into new audio-over-IP technologies."
Tieline is a leading manufacturer of broadcast quality audio codecs and has focused on helping broadcasters transition from circuit switched POTS, X.21 and ISDN technologies into packet-switched IP technologies. "As broadcasters are now being forced to migrate to IP networks, they are looking to the EBU and manufacturers to establish a global standard for reliable broadcasting over IP networks," Levy said. "This includes interoperability between brands over these new networks."
With the proliferation of high-speed LAN connections and high-speed 3G networks around the globe, demand for flexible and reliable IP codecs is growing exponentially. "Since 2005 Tieline has been shipping IP solutions over wired and wireless networks," said Tieline Research and Development Manager PJ Fall. "In 2007 the EBU released specifications for IP compatibility and Tieline has complied with these and successfully tested our codecs with a number of European codec manufacturers - including our interoperability over IP using SIP."
The implementation of SIP makes it simple for broadcasters to connect over IP without having to acquire dedicated IP addresses. Codecs and other SIP-registered devices can simply dial another SIP-registered device and connect - just like making regular phone calls. Tieline codecs can make direct peer-to-peer calls using SIP or dial through a SIP server, which connects to other devices that are registered to SIP servers.
SIP technology is increasingly pervasive in a multitude of IP products and its natural integration into the IP world will continue because of its ability to evolve, and its flexibility in connecting to any SIP-compatible device. SIP is the protocol supported by most telcos for VoIP interoperability.
"IP and SIP technologies are the future of broadcasting and more and more we are seeing broadcasters embrace them," Darren Levy said. "IP proliferation is still in its infancy but broadcasters are seeing the cost advantages over ISDN and the flexibility that the technology provides, particularly in the wireless arena."
Tieline is committed to developing new IP and 3GIP applications that take advantage of new network infrastructures around the globe. Alliances with technology partners such as the Audio-via-IP Experts Group will also create new opportunities through collaboration on technology requirements.
Tieline codecs featuring IP, 3GIP and SIP interoperability can be ordered for demonstration at any Tieline international office in the US, Netherlands, and Australia or from any listed Tieline dealer at www.tieline.com
