AV over IP routes audio and video signals across a standard IP network instead of dedicated AV cabling and proprietary matrix switchers. It has become the standard for modern AV deployments because it gives IT teams the same visibility, scalability, and management tools they already use for the rest of the network, without maintaining a completely separate AV infrastructure alongside it.
Blog 1 of 8 in the series: What AV Topics Should I Be Paying Attention to in 2026?
- AV-over-IP routes audio and video across standard IP network infrastructure, replacing dedicated cabling and proprietary matrix switchers.
- Routing is handled in software, making changes a configuration update rather than a hardware swap.
- Common standards include SDVoE for lossless video, NDI for compressed video, and Dante for audio distribution.
- Misconfigured network switches are the most common cause of AV-over-IP failures, not hardware defects.
- Remote monitoring platforms like Crestron XiO Cloud make system management possible from a single dashboard across every room.
What Did Traditional AV Signal Distribution Look Like?
Before AV over IP, distributing audio and video meant proprietary matrix switchers: physical hardware that routed signals from sources to displays through dedicated cabling. A 16x16 matrix switcher could route any of 16 inputs to any of 16 outputs, but adding a 17th meant replacing the switcher or buying expansion hardware. Cabling ran point to point, and the whole system existed completely separate from the IP network.
The Limitations That Pushed Organizations to Change
It worked. But it created an island. AV lived in its own world with its own cabling, its own hardware, and its own support model. IT had no visibility into it. Expanding or changing anything meant swapping physical hardware, often on a timeline that did not match how fast the business needed to move. Three problems kept surfacing: scaling was expensive, IT could not manage the system, and every refresh required ripping out proprietary gear.
How Does AV over IP Work Differently?
AV over IP replaces the matrix switcher with network switches. Encoders at each source convert the signal into IP packets. Decoders at each destination convert those packets back into audio and video. Routing is handled in software: changing what displays what is a configuration change, not a hardware change.
The network infrastructure is completely standard: 1 Gbps or 10 Gbps managed switches, VLANs for traffic segmentation, and quality-of-service policies for prioritizing AV traffic. These are tools IT teams already know how to manage.
What Network Infrastructure Does AV over IP Actually Require?
A properly deployed AV-over-IP system needs specific things from the network. The most common cause of AV-over-IP failures in production is not hardware. It is misconfigured switches. Working with an integrator who genuinely understands IP networking is the most important thing you can do to avoid that outcome.
Switch and VLAN Requirements
- Managed switches with 1 Gbps or 10 Gbps ports, depending on codec and resolution requirements
- A dedicated VLAN for AV traffic to prevent contention with general IT traffic
- Quality-of-service (QoS) policies that prioritize AV packet delivery
- Sufficient uplink capacity between switches to handle peak AV traffic loads
Multicast and Routing Requirements
- Multicast routing enabled for systems using multicast distribution, which is most of them
- IGMP snooping configured on all switches in the AV path to prevent multicast flooding
- Proper PIM (Protocol Independent Multicast) configuration on Layer 3 switches for multi-subnet deployments
What Are the Most Common AV over IP Standards?
A few standards are in active use. Knowing the differences matters when specifying a system.
Video Distribution Standards
- SDVoE: Zero-compression, lossless video over 10 Gbps Ethernet. Lowest latency, highest image quality. Used by Crestron, ZeeVee, and Black Box among others.
- NDI: Compressed IP video developed by NewTek, widely used in production and broadcast environments. Runs well on 1 Gbps networks.
- AVB/TSN: IEEE standards for time-sensitive networking, used in environments requiring precise synchronization.
Audio Distribution Standards
- Dante: The dominant standard for AV-over-IP audio distribution. Supported by hundreds of manufacturers including Shure, Biamp, QSC, and Yamaha. Most enterprise AV deployments pair Dante for audio with SDVoE or a compressed video standard for video routing.
How Does AV over IP Change Long-Term System Management?
Traditional AV systems required on-site visits to diagnose issues, replace hardware, or push firmware. With AV over IP, most of that happens remotely.
Remote Monitoring
Platforms like Crestron XiO Cloud give real-time status for every device on the network. When a display goes offline, an encoder loses signal, or firmware falls out of date, the monitoring platform sends an alert before a user even notices.
Firmware Management
Firmware updates are pushed across the network on a schedule, not by someone physically touching each device. This remote management capability is the foundation of modern Day-2 support: the managed service model that keeps AV systems running reliably long after the installation crew has gone home.
For more on what that support model should look like, see What Is AV Day-2 Support, and What Should I Expect from My Integrator After Installation?.
Is AV over IP Right for Every Environment?
For most enterprise environments with more than three or four rooms, yes. A single small room might not justify the network complexity. But any environment with multiple rooms, multiple buildings, or plans to grow will benefit from AV-over-IP architecture from day one. Retrofitting to AV over IP later is significantly more expensive than designing for it upfront.
Frequently Asked Questions
What is AV over IP?
AV over IP routes audio and video signals across a standard IP network instead of dedicated AV cabling and proprietary matrix switchers. Encoders at the source convert the signal into IP packets. Decoders at the destination convert them back. Routing is handled in software, using the same switches and infrastructure IT already manages.
What network speed does AV over IP require?
Most AV-over-IP systems need a minimum of 1 Gbps per endpoint for uncompressed video. Compressed codecs like NDI run effectively on 1 Gbps networks. For large deployments with uncompressed 4K and high endpoint density, 10 Gbps infrastructure is the right call.
Does AV over IP require a dedicated VLAN?
Yes. AV-over-IP traffic should be segmented on its own VLAN to ensure quality of service, prevent bandwidth contention with general IT traffic, and make monitoring and troubleshooting straightforward. This is standard practice in any AV-over-IP deployment.
What is the difference between AV over IP and SDVoE?
SDVoE (Software Defined Video over Ethernet) is a specific zero-compression AV-over-IP standard from the SDVoE Alliance. It delivers lossless video over 10 Gbps Ethernet with ultra-low latency. AV over IP is the broader category. SDVoE is one well-established standard within it.
How does AV over IP affect system lifespan?
AV-over-IP systems age more like software than hardware. Features, security updates, and improvements come via firmware pushed across the network, not through hardware replacement. Organizations typically see system lifespans of 7 to 10 years, compared to 4 to 6 years for traditional proprietary AV.
What are the biggest risks when deploying AV over IP?
The most common issues are insufficient network infrastructure, missing VLAN configuration, and poor coordination between AV and IT teams. Working with an integrator who genuinely understands both AV and IP networking takes most of that risk off the table.
