AV OVER IP

connectivity towards the IP world. “In 2016, Lawo V__remote devices were used for the Euros in France to transport production streams from the OB trucks at the venues to an International Broadcast Centre over fibre optic,” he recalls. “Back then, this was a revolution. V__matrix, a software-defined processor, was released only a couple of years later, providing gateway duties between SDI and IP, while simultaneously venturing into video processing. “The C100 processing modules it contained could be repurposed by uploading different software to them. This changed how soccer was covered – at first in Australia and later also in the rest of the world.”
he expected at this point in time, he responds: “No, it’s not where I expected it to be. Adoption is still pretty fragmented. Different parts of the industry are using different tools, and even different parts of a single system might rely on separate protocols. For example, the integration world leans toward AES67, loudspeaker manufacturers like us are leading the charge with AVB/Milan, and then a lot of people are using Dante because it has so many tools available.” IP MILESTONES Invited to consider Lawo’s own IP milestones, Scheck first discusses an event held nearly ten years ago that marked the shift from legacy (SDI)
Scheck highlights Lawo’s instigation and contribution to the development of the Ravenna audio transport protocol, ‘which in turn inspired the AES67 standard’. The company continues to regard ST 2110 and Ravenna as “robust and versatile, especially for large projects – such as those in large arenas, stadiums, concert venues and broadcast – with tens of thousands of audio channels and a huge number of video streams that must be delivered not just on-premises but also elsewhere in the world,” he says. Brian Fraser, head of product and technology at Adamson, depicts a present state-of-play that is more complex. When asked whether the adoption of IP has reached the level
