A maintenance revision to the streaming AoIP standard AES67-2013 has been issued, according to an announcement from the Media Networking Alliance, an industry group promoting AES67 adoption and standardization.
AES67-2015 includes updated references to RFC 7273 and clarifications in 6.3, 8.1, and 8.5. According to the release, the revision address “interoperability requirements, based on general implementation and “plugfest” experience.”
These revisions were identified in October 2014 during the AES Plugfest 1 testing, in cooperation with the European Broadcast Union at the Institut für Rundfunktechnik in Munich.
Technical personnel representing the IRT, Swedish Radio and the BBC assisted in the plugfest tests and observed the outcomes on behalf of the EBU. Ten companies (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.) tested 16 available networked-audio products with AES67-specific extensions against each other to confirm interoperability.
Media Networking Alliance Technical Chairman Kevin Gross said, “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.” He added, “As proven in the Plugfest testing, AES67 functional compatibility performs as described and these revisions further complement that functionality.”
