STUDIO While it’s new and a break from traditional workfl ows, IP as a broadcast standard is essentially a simple concept – all devices in a multi-camera facility are connected via an IP router. Any legacy devices that use SDI are converted to IP. This offers greater fl exibility and greater possibilities. From a studio installation point of view, this simplifi es things greatly, plus it allows for a greater level of redundancy. Using IP switches, you can employ an automated failover system (without interruption), for very little cost. If a traditional video router failed – once you’d picked yourself up off the fl oor – you’d need to manually patch every signal as required to ‘patch around’ the router. Cost is an important factor here as traditional video routers are sized and defi ned by the number of physical ports, and that bears a direct relationship to their cost. With IP switches, the size of the router is defi ned by its total bandwidth, not the physical ports, as each port of an IP switch can carry multiple signal paths and are inherently bi-directional. The drive behind moving to an IP broadcast model has been helped varying factors including the SMPTE 2022 standardisation of video over IP. Plus the adoption of 10-Gigabit Ethernet rather than 1-Gigabit Ethernet in some devices – and now increasingly 40-Gigabit Ethernet devices – demonstrates the industry is embracing a bandwidth hungry, IP ready audience. 60 | KITPLUS - THE TV-BAY MAGAZINE: ISSUE 104 AUGUST 2015 Perhaps the most forward-looking and game-changing feature that IP broadcast can bring to the party is remote production. From a vision mixing point of view, the vision mixer and operator don’t even need to be at the same venue as the event or production. It can all be connected via Ethernet, and across the Internet. It’s an exciting premise. But it’s what users want to achieve with vision mixers today that’s the biggest change. New breeds of users and different types of organisations, such as corporates, educational and minority sports institutions are all now broadcasters. They’re all trying to reach and engage with new audiences. To do that they need more functionality and intuitive operation – and all at a reduced cost. So what are vision mixers going to look like in the future? They’ll probably always look fairly similar – lots of buttons, a ‘T-bar’ – but they’re certain to be more powerful then ever before.
