Tieline Technology announces new IP codec

AUSTRALIA, IBC: Leading codec manufacturer Tieline Technology has announced the development of a low cost, high performance stereo IP codec, for main or backup studio-to-transmitter links, audio distribution and simple remote broadcast links.

"Tieline’s new Bridge-IT IP codec is the perfect solution for low cost, point-to-point IP audio links,” said Darren Levy, Tieline Technology’s International Marketing Manager. "Bridge-IT will deliver studio quality audio over a variety of IP data networks such as wired and wireless WANS, LANS, the Internet, satellite IP, Wi-MAX and Wi-Fi."

Bridge-IT has an SD card slot for failover playback of prerecorded audio and the unit’s user-friendly menus can be fully programmed using comprehensive front panel hardware that includes a keypad and LCD display, or by using a web interface. It is designed for desktop use or two units can be installed side-by-side in a purpose-built 1RU mounting bracket.

"Bridge-IT leverages off the reliability of Tieline’s existing G3 codec range with the inclusion of the QoS Performance Engine technology for managing lossy IP network connections," said Levy.

It will also be SIP-compatible and will connect to all major brands of codecs, as well as to our existing G3 range of codecs. Tieline is also implementing a Traversal server solution for very simple negotiation of firewalls, automatic address book population of other codecs in your network (codec buddy list) and one-touch dialing.

Bridge-IT comes with a range of high performance broadcast algorithms plus optional AAC LC and AAC HE. Standard algorithms include 16 Bit 22kHz linear audio at less than 12 ms encode delay for uncompromised audio, G.711 G.722, MPEG Layer 2 and Tieline Music.

The Tieline MusicPLUS algorithm also provides 22 kHz mono, dual mono and stereo with 20ms encode delay at under 100 kbps, offering huge savings on your IP data bills and outstanding audio quality.

Unlike most low cost IP audio codecs, Bridge-IT has all the broadcast input connectors you would expect on a fully-featured codec. Simultaneous analog and digital AES/EBU audio outputs are provided on XLR connectors and it includes a ¼” (6.35mm) stereo headphone output.

Tieline’s Bridge-IT codec and Traversal server solution will be on display during IBC 2009 at Booth 8.E75 (Hall 8) and is expected to ship in the final quarter of 2009.
