Understanding the Livewire+ AES67 Protocol
TVTechnology.com reports that over the last 15 to 20 years, broadcast audio systems have undergone revolutionary changes—from analog to digital technologies, from manual to computer-assisted workflows, integrating related systems such as telephones and intercom systems, and much more.
One key enabling technology is Audio over IP (AoIP), which delivers a number of significant benefits, including operational flexibility, scalability and lower costs. However, implementing AoIP systems to take advantage of these benefits depends almost entirely on the existence of and support for interface and interoperability standards to ensure that the many elements that make up professional audio systems are capable of working together. To that end, there are several AoIP protocols designed to achieve this goal by easing implementation and integration, including the increasingly popular Livewire+ AES67.
Originally known as Livewire, this pioneering technology was created in 2003 by the Telos Alliance as a means of transmitting low-latency, high-reliability audio over switched Ethernet. Livewire+ AES67 adds full compliance with the AES67-2013 interoperability standard for high-performance AoIP transport over IP audio networking products. This allows devices to seamlessly connect directly to Livewire+ networks for connecting audio streams, regardless of device type or manufacturer. Livewire+ AES67 also offers the flexibility to incorporate and comply with future AES and SMPTE standards as they are approved and released, while simultaneously offering backward compatibility with the RAVENNA networking protocol.
