Audio Over IP Interoperability with AES67
Many competing Audio over IP protocols have emerged over the last several years and have been implemented in certain markets by various manufacturers. However, equipment using incompatible Audio over IP protocols often needs to be part of a single system. Without an interoperability standard, designers and integrators have been forced to modify their equipment choices or abandon audio networking altogether, sacrificing the flexibility of an IP solution.
The AES67 standard provides interoperability between the predominant Audio over IP protocols in use today. AES67 was developed by the Audio Engineering Society, published as an open standard in 2013, and most recently updated in 2018. In 2017, SMPTE published ST 2110, a standard for professional video over IP, which uses AES67 as the audio transport. AES67 is an interoperability standard that acts as a translator between protocols.
To take advantage of AES67 within a networked audio system, all system components must have implemented AES67 by itself or on top of their native protocols. Therefore, it is highly advisable to research what is implemented on the specific devices that will interconnect via IP within a design.
AES67-Enabled Products from Extron
Extron offers a full lineup of Audi over IP and AV over IP products that allow AV integrators to include networking technology into a variety of applications. These products deliver reliable performance and flexibility in the distribution of AV signals, and many additional integrator-friendly features to meet your audio system needs.
For system designs where required devices utilize differnt AV over IP protocols, AES67 provides interoperability between AES67 capable devices on the network.
