Tieline Technology will demonstrate its new QOS Performance Engine Technology over IP for its G3 family of audio codecs at the 2008 NAB Show.

The company says QOS provides greater connection stability, with less delay, for live remote broadcasts over IP networks.

Tieline noted that the Internet and 3G wireless networks are lossy packet-switched networks in which a percentage of data packets sent never arrive. "It's not unreasonable to expect that between 1 percent and 3 percent of packets sent will be lost at different times over open Internet IP connections," said Neil Morrish, Tieline research and development manager. "Over 3G networks, this figure is likely to increase at times to between 3 percent and 10 percent of packets sent."

Broadcasters are unable to buy QOS (Quality of Service) for wireless 3G networks, and it is often impractical to buy QOS for a single remote broadcast over the Internet, so the QOS Performance Engine Technology solution provides reliable managed audio over these networks, according to Tieline.

"Our new IP QOS Performance Engine automatically manages the IP connection," said International Marketing Manager Darren Levy. "It dynamically adjusts settings in the codec to allow for varying packet arrival times as well as providing multi-strategy Forward Error Correction (FEC) analysis, which replaces lost or corrupted packets in a data stream."

Tieline joined the Audio-via-IP Experts Group because we believe that that codec manufacturers need to collaborate in establishing a global standard for reliable broadcasting over IP networks.
