Bothell, WA (December 31, 2014)—A recent plugfest involving equipment from 10 manufacturers demonstrated interoperability between a number of different implementations of the AES67-2013 networking standard.

The plugfest, held at the Institut für Rundfunktechnik (IRT) in Munich, Germany, was hosted by the AES in cooperation with the European Broadcast Union (EBU). Participating manufacturers included ALC NetworX GmbH, Archwave AG, Axia Audio, Digigram SA, DirectOut GmbH, Georg Neumann GmbH, Lawo AG, Merging Technologies S.A., SOUND4 and Telos Systems Inc. Technical personnel from IRT, Swedish Radio and the BBC assisted in the tests and observed the outcomes on behalf of the EBU.

All products tested are currently available networked-audio products with AES67-specific extensions. Implementations varied from software implementations on a PC to hardware-based FPGA solutions. Tests were chosen to demonstrate audio streaming interoperability between each device as a transmitter, and all other units as receivers. All devices were used to test synchronization and primary interoperability.

AES67 is a standard to enable high-performance audio-over-IP streaming interoperability between the various IP based audio networking products currently available, such as Dante, Livewire, Q-LAN and RAVENNA. It is not a new technology but a bridging compliance mode common to all IP-Networks; a mode you can put a device into, on any participating network. AES67 operates over standard layer 3 Ethernet networks and, as such, is routable and fully scalable, like any common modern IT network. The Media Network Alliance (MNA) has been recently formed to promote adoption and support adopters of the newly ratified standard, through a program of education, marketing, and ongoing technical support for the standard.

According to Stefan Ledergerber, director R&D Lawo Group and member of the MNA steering committee, "The Plugfest proved that AES67 is not vaporware, it works. It is the ideal form of making the various existing technologies talk to each other and giving the users the possibility to interconnect a huge variety of equipment, based on open standards."
