AUS: Leading codec manufacturer Tieline the Codec Company has announced a new firmware release v3.02.12 for Gateway and Gateway 4 codecs supporting RAVENNA®. 

RAVENNA is used widely by broadcasters around the world to advertise and discover streams when streaming real-time IP audio. Integrating RAVENNA support facilitates interfacing easily between Gateway and Gateway 4 codecs and RAVENNA devices over AoIP networks.

“Ever since the days of POTS and ISDN, Tieline has always advocated for interoperability of equipment from different manufacturers,” said Charlie Gawley, Tieline’s VP Sales APAC/EMEA. “The world of IP is no different. It’s why our Gateway platform is AES67, ST 2110-30, NMOS and now RAVENNA compliant, allowing devices using different AoIP protocols to connect seamlessly.” 

Tieline codecs specialize in streaming low latency, high quality audio over a range of wired and wireless IP transports and facilitate the integration of compressed and uncompressed IP audio streams around the broadcast plant. The codecs are often gateway devices in IP networks bridging between wide area network (WAN) nodes that may include the broadcast plant, other studios (inter-studio links), production facilities and live events. Gateway and Gateway 4 codecs deliver a flexible platform capable of adeptly routing audio between a range of equipment using proprietary AoIP protocols like WheatNet-IP, as well as devices supporting RAVENNA, AES67 and ST 2110-30. 

The new firmware release is a free upgrade for existing customers. Release notes can be viewed, and firmware downloaded, from the support page for each codec available via:
