You may have noticed if you look at an AV switcher or the back of an LCD screen that there is a complicated array of inputs for PC, video, and audio. The advantages of this technology are that it’s fairly simple to plug local devices in and if deployed correctly it’s easy to switch between them.

However, there are some disadvantages and one only has to recognise that they are streaming video from Netflix or iTunes at home to feel that there has to be an alternative. In fact, there is. Some finger-on-the-pulse types amongst you will know that AV over IP (Audio Visual over Internet Protocol) is an option.

AV over IP is not particularly complicated, nor is it particularly new; IP networks have been used for video conferencing, video streaming and digital signage. However, the technology is currently under-utilised in a more traditional av environment

There are several reasons for this:

1)      AV experts like to stick to what they know; Circuit-based AV is something they’ve been implementing for a long time and they know how to make it work.

2)      Like with a lot of new technologies, early examples of AV over IP needed improvement to be regarded a realistic alternative:

a.       IP networks can be expensive when transmitting high-quality (and therefore high-bandwidth consumption) content

b.       To manage expense, one can implement a 1GB Ethernet. However then significant compression would be needed to achieve reasonable quality

c.       Compression can lead to delay, which damages ease of use and AV experience, especially when transmitting PC images (try using a mouse or flipping PowerPoint slides on a screen with major delay)

d.       4K60 content is more pervasive nowadays and this was not transmittable over 1GB Ethernet (even if your current assets are not 4K, there is every chance that will change in the future).

Recently there have been some significant developments in this technology. For example, Crestron specify that their new NVX can deliver 4K60 4:4:4 content with no delay over 1GB Ethernet. If this can be achieved, why is this so compelling?

1)      You can transmit significantly more sources to your Audio Visual Devices than a traditional AV set-up.

2)      You can reduce installation time whilst improving the appearance of an AV Installation as you only need to run one cable rather than many.

3)      You can transmit your audiovisual assets over much greater distances using copper or fibre IP cabling.

Now is an excellent time to consider using AV over IP as you build or refresh your audio-visual facilities. Speak with us now to learn more about whether AV over IP is the right direction for your business.
