AV over IP (Audiovisual over Internet Protocol) technology has been around for more than a decade; hailed as a revolutionary innovation in the AV industry for its potential to transmit data from multiple sources to a huge number of outputs.
However, although it is one of the biggest trends in the professional AV field, it is still evolving and being slowly adopted, and for many AV professionals, it is still a bit mysterious. What role does that pile of black boxes actually do in the control room? How is it different from other control room solutions?
So what is AV over IP?
AV over IP (or networked AV as it is commonly known) is the transmission of audio, video and other signals over the internet, LAN or WAN networks.
It takes a signal from an AV source, such as a media player or PC and passes it through an encoder, which breaks it down into manageable chunks of digital data called packets. This data travels through the network and is converted back into a compatible AV signal when it reaches the decoder. The signal is then received by the output device (speaker, display, projector etc.)
When transmitting and receiving from multiple sources, a network switch operates as the focal point between the encoder and decoder, providing separate connections for each input and output device.
What are the benefits of AV over IP?
At first glance, AV over IP systems look very similar to traditional AV networking solutions such as HDBaseT, but the use of an IP network brings some key benefits.
Highly scalable
Network based system can accommodate very large number of devices- not limited by physical ports on switches, can be expanded with IP ports and only limited by the IP network it is connected to.
Saves cost by avoiding buying expensive AV switches and gives the ability to manage a large number of multi-point displays from a single investment.
Easy to install
One of the key benefits of AV over IP is that it can utilise existing network infrastructure, depending on the bandwidth required.
Far less cabling with only one cable type: category cable (ethernet).
Removes physical point-to-point connections, making changes and replacements simpler and more efficient.
Cost savings
As you can utilise existing networks and equipment if your bandwidth requirements are low, there is minimal costs to move to an AV over IP system. The costs for scaling up are also significantly less that alternative networks.
Secure & manageable
Can use same methods employed by IT departments- creating specific zones/areas and enabling authorisation.
Easy application of encryption technologies.
Greater distance
- AV over IP can be transmitted over fibre optic or copper cable easily, and although the category cable has a maximum distance of 100 meters, you can add switches and repeaters to increase the distance.
- Through IP networks data could theoretically be sent over networks to anywhere worldwide.
