AV Over IP Managed Switches

AV over IP stands for Audio-Visual over Internet Protocol. It’s a method of transmitting audio, video, and control signals over standard network infrastructure like Ethernet (instead of traditional AV cabling like HDMI or SDI).

 

Key Concepts:
AV: Audio and video signals, like what you’d use in a conference room, digital signage system, or broadcast setup.

IP: Internet Protocol, the same technology that powers computer networking and the internet.

 

How It Works:
Instead of sending AV signals through dedicated AV cables, the content is converted into data packets, sent over an IP network (LAN, WAN, or the internet), and then decoded back into audio/video at the receiving end.

 

Benefits:
Scalability: Easier to add or move displays and sources.

Flexibility: Can route signals to any device on the network.

 

Cost Efficiency: Reduces the need for expensive proprietary switchers.

Longer Distances: Unlike HDMI or VGA, which degrade over long runs, IP can transmit over much longer distances with no signal loss.

 

Common Use Cases:
Digital signage in airports and malls

Corporate AV systems

Campus-wide broadcasting in schools

Live event production
