AV OVER IP

Telos Alliance helped pioneer AoIP for broadcast, with Axia Audio launching the first Ethernet-based studio gear in 2003
likely to slow their performance down or making certain things downright impossible even though operators require them.” Home Apps are available for video, audio, ancillary and utility workflows. One recent development means that some of them can now be operated from a mobile device for commentary, video monitoring and mixing scenarios that involve two or more mixing consoles of different sizes. Scheck adds: “The next chapter for Home Apps will be to run alongside processing applications from other vendors, complete with the ability to exchange data via a shared-memory approach on a so-called Media Exchange Layer (MXL). IP will still be required, of course, but clever scenarios are being developed to further compress latency. However, users will always need gateways for signal input/output, and controllers such as mixing consoles.” AGNOSTIC OR NOT? With a variety of transport formats continuing to be used in live and other areas of pro AV, it’s to be expected that many vendors continue to prioritise the accommodation of different network technologies – and Lawo is among them. “Multi-format support is probably more important today than it was five years ago,” says Scheck, “because, depending on the importance of the event to be covered, different equipment requiring different IP protocols is used. This calls for infrastructure that speaks several protocols fluently and translates them
For Barco, Bruce highlights the development of its Nexxis platform, which was developed for integrated digital operating rooms. “Nexxis enables uncompressed, high-resolution video and audio sharing with near-zero latency, making it a game changer for surgical precision and collaboration,” he explains. “This solution paved the way for Barco’s interest in creating and supporting a standard for compressed and uncompressed workflows. Through this effort, we contacted Aims to see if they would be interested, and a few months later, it was put to a vote at IBC. Michael Cronk, chair of the Aims group, was surprised by the overwhelming support for the initiative, and IPMX was born.” The company has a number of new products supporting ST 2110 and IPMX, including the IO-H1, IO-H25 and IO-S25 gateways. LATEST INNOVATIONS Invited to nominate its latest major innovation for audio over IP, Scheck mentions Lawo’s Home Apps for IP infrastructures, which are single-purpose applications that run on generic servers and in the public cloud where the latter is required. “Their containerised microservice architecture means that they automatically scale to future server generations with ever more processing cores,” he explains. “This flexibility is due to the fact that they were programmed from the ground up for a disruptive – at least for broadcasters – approach, without the slightest legacy elements
