Amsterdam, Netherlands (February 5, 2014)—Audinate plans to incorporate the AES67 transport standard, published by the Audio Engineering Society in September, 2013, in its Dante media networking solution.
The new AES67 standard provides interoperability recommendations for professional quality audio networking in the areas of synchronization, media clock identification, network transport, encoding and streaming and session description.
“Audinate does not see networking protocols as competing technologies but more like tools in a media networking toolbox. From the beginning, Audinate has incorporated and built upon standards to develop the Dante solution,” stated Aidan Williams, CTO of Audinate. Williams adds, “AES67 will provide another option for interoperable layer 3/IP-based audio networks in the future.”
Dante implements a layer 3 IP-based transport based on the User Datagram Protocol (UDP). AES67 uses the Real-time Transport Protocol (RTP). The addition of AES67 support provides a choice of transport protocols within Dante. Both UDP and RTP were developed by the Internet Engineering Task Force (IETF). To achieve interoperability, AES67 mandates a specific RTP payload format for delivering audio over IP networks as well as methods for exchanging information about audio streams. RTP is already used extensively in communication and entertainment systems that involve streaming media—such as VoIP telephony, video conferencing, and IP television. Since the existing Dante transport and AES67 both use routable L3 IP protocols, Dante can operate in routed networks, spanning multiple IP subnets, using either protocol.
Audinate will deliver AES67 support as a firmware update to OEMs in initial Dante products within 12 months.
