AV over IP/ Education

EDUCATION

AV over IP promises to take full advantage of the convergence of AV and IT, with the ability to distribute video, audio and control signals over traditional network infrastructure. The AV over IP model differs from existing classroom AV designs in that it's essentially a streaming infrastructure. We're all used to video and audio streaming over the network, but AV over IP technology is taking streaming to a different level.

The AV over IP model differs from existing classroom AV designs in that it's essentially a streaming infrastructure. Instead of placing HDBaseT transmitters and receivers at all the devices in the room, the AV over IP model calls for an encoder at each source device and a decoder at each destination device. The encoders and decoders are all connected to standard Ethernet switches. As a result, we're no longer limited to a finite number of inputs and outputs, and theoretically we can connect as many encoders and decoders as our network design allows — with the ability to scale up at lower costs. Based on the network configuration, we're also no longer limited to AV signals being confined within the room. The decoders can be controlled to display any stream from any of the encoders.
AV and IT professionals pay attention to bandwidth restrictions, and the AV over IP trend is certainly in the thick of the bandwidth discussion. While it might sound like an easy solution, you can't just start throwing these high-end AV encoders and decoders on your network and expect flawless results. There are different classes of these encoders and decoders; for instance, some brand offers everything from low-bandwidth H.264 compression that's friendly to your enterprise networks, to higher bandwidth technology like JPEG2000 compression, and beyond. When comparing AV over IP technologies, pay attention to bandwidth requirements and explore the possibility that you'll need to establish a separate, dedicated AV network to keep your network services department happy.
As you start to investigate the various AV over IP technology that's being offered, there are quite a few features and limitations that you need to pay attention to. Different manufacturers have different resolution, frame rate and color compression capabilities. Some may boast that they can offer 4K60 4:4:4 video, but then you'll find out that they require a 10 Gb/sec switch, while others claim they can do it over a 1 Gb switch. Even if you're not yet heavy into 4K-resolution sources and display devices in your classrooms, you should certainly be planning the infrastructure to handle it in the future. Achieving 4:4:4 color sampling is the goal, but plenty of manufacturers are using 4:2:0 compression to save on bandwidth. Screen reader support enabled.
