PUTTING THE USER
IN CONTROL OF A O IP IP-based audio is commonplace throughout broadcast and pro AV, but vendors need to retain an agnostic approach to networking transport and control
f you wanted to date-stamp the moment Audio over IP (AoIP) began the rise to its current industry prominence, you might opt for the 2006 development of Dante media networking technology by Audinate. In the 15 years since its launch, Dante has remained at the forefront of IP audio technologies. The September 2013 publication of the AES67 standard cemented a level of interoperability
between other AoIP tech. More recently, AES67 was incorporated into the broadcast-orientated SMPTE ST 2110 standards suite that is being widely adopted in broadcast centres and OB vehicles. Michael Naugle, design engineer for NEP’s US Broadcast Services team, confirms some use of SDI will continue for the foreseeable future, but the new trucks NEP is building are IP. The company has already unveiled multiple ST 2110-compliant OB vehicles, and Naugle says the company uses Dante extensively. "I think there will be some SDI infrastructure in new vehicles in order to tie in to some legacy equipment," says Naugle. "But my expectation is all future facility developments will be based around IP." TSL Products has been developing AoIP solutions for many years now. Berny Carpenter, TSL’s audio product manager, says the company’s success partly rests on “having an agnostic approach to IP audio; we let customers work with the networking technology they want to use”. For companies needing direction on what to adopt, Carpenter says, “TSL’s team typically considers a few key questions: what are they trying to achieve, and what is the scale of the network, then recommend a route on that basis.”
