Revision to AES67-2013 added to aid interoperability
A maintenance revision to AES67-2013, the AES standard for high-performance streaming audio-over-IP interoperability, has been issued.

The revision, called AES67-2015, clarifies some of the interoperability requirements, based on general implementation and 'plugfest' experience.

The possibility to incorporate these revisions was identified during the AES ‘Plugfest’ testing, carried out in cooperation with the European Broadcast Union (EBU), in October last year, and held at the Institut für Rundfunktechnik (IRT), in Munich, Germany. During these tests ten companies tested 16 currently available networked-audio products with AES67-specific extensions against each other to confirm interoperability.

Commenting for the Media Networking Alliance, the industry alliance established to promote awareness and uptake of AES67, Technical Chairman Kevin Gross, stated: "The limited scope of these revisions is testimony to the robust and stable nature of AES67 as originally published and successfully implemented by numerous audio manufacturers. As proven in the plugfest testing, AES67 functional compatibility performs as described and these revisions further complement that functionality."

AES67-2015 includes updated references to RFC 7273 and clarifications in 6.3, 8.1, and 8.5.
