Tieline recently announced a new firmware release v3.02.12 for Gateway and Gateway 4 codecs supporting the RAVENNA protocol. RAVENNA is used widely by broadcasters around the world for discovery and advertisement when streaming real-time IP audio. Integrating RAVENNA support facilitates interfacing easily between Gateway and Gateway 4 codecs and RAVENNA devices over AoIP networks.

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.

IP Stream Discovery and Advertisement

AES67 and ST 2110-30 only address stream transport, packet setup and synchronization (timing). Nothing is mandated regarding discovery.

Interoperability with NMOS and RAVENNA

Gateway and Gateway 4 codecs are compliant with AMWA NMOS standards IS-04 and IS-05 which delivers discovery, registration, and ultimately control for ST 2110 AoIP streaming. NMOS data models and open standard APIs deliver a new level of interoperability and control with networked equipment throughout the stations and networks. NMOS will deliver more functions and greater interoperability between IP devices from different vendors over time. More straightforward interoperability between products is important as it allows end users and service providers to build better systems with streamlined management and control options.

Many broadcast networks around the world use RAVENNA for stream discovery and advertisement. The recent integration of RAVENNA allows Tieline codecs to perform these tasks over RAVENNA 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 RAVENNA compliant, allowing devices from different vendors to connect seamlessly.”

More NMOS features and capabilities will be developed in Tieline codecs and integrated over time via firmware updates.


Tieline offers optional WheatNet-IP cards at purchase to interface directly with a WheatNet-IP network. Codecs then appear as Blades and seamlessly support stream discovery, advertisement and control using Wheatstone’s Navigator software.
