Telos Alliance Says 'AES67 is Safe'
Patent claims dim enthusiasm for audio networking
CLEVLAND, OHIO—Straight from the Telos Alliance: Since the adoption of the AES67-2013 on Sept., 2013,
interest among broadcast audio professionals regarding networked audio-over-IP
interoperability has grown.
this spike in interest has led certain manufacturers of broadcast audio
networking equipment to claim intellectual property patent rights over
implementations of AES67, damping broadcasters’ enthusiasm for the standard and
the technology behind it.
According to Greg Shay, chief science officer of The Telos Alliance, broadcasters needn’t worry about
“We’ve heard of broadcasters
receiving notifications that AES67 infringes on pre-existing patents,”
Shay said. “I’m here to tell you, that’s not the case. All the principles of AES67 are contained in Axia Audio
Livewire audio-over-IP technology and the prior art. Livewire was introduced in
2003 and became a commercial success around the world years before these other
patent claims were filed.”
“We’ve always believed
strongly in the many benefits that interoperation and audio-over-IP networking
bring to the broadcast industry,” he said. “So you can understand our dismay
at other parties’ claims that encumber this good work.”
Patent holders must defend their intellectual property—assuming it is
valid. The Telos Alliance announced the availability and shipment of the fully compliant AES67 implementation in its Axia Audio xNode
AoIP Interface in November 2013, and has been shipping these products around the world. During that time, no communication, contact,
injunction, or any notice of infringement has been received from any third-party; clear evidence that implementing AES67 has not subjected The Telos
Alliance to any third-party claims.
“Livewire technology clearly predates these other systems,” Shay said. “In fact, Telos
was a sustaining member of the X.192 working group which developed the AES67
specification, and we are making our own relevant patents and intellectual
property available without cost for use in implementations of AES67. With that
in mind, we’re calling on this company to abandon any claims of intellectual
property rights over implementations of AES67, and join the Telos Alliance and
the rest of the industry in unfettered support of this standard.”
“AES67 is safe,” he said.
