Indianapolis - Mar 20, 2008 - At the 2008 NAB Show, Tieline Technology will demonstrate its new QOS Performance Engine Technology over IP for its G3 range of audio codecs, which provides greater connection stability, with less delay, for live remote broadcasts over IP networks.

The Internet and 3G wireless networks are lossy, packet-switched networks in which a percentage of data packets sent never arrive. Tieline notes that between one and three percent of packets are lost at different times over open Internet IP connections. This figure likely increases to between three and 10 percent of packets via 3G networks.

In a remote broadcast situation, 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 for the Internet. The QOS Performance Engine Technology is Tieline's answer to this. The technology manages the IP connection and adjusts settings in the codec to allow for varying packet arrival times and provide forward error correction (FEC) analysis.
