AV over IP: Why the Industry Is Moving Away from Point-to-Point Distribution
Traditional AV systems connect individual sources, switchers and displays through fixed cable paths. AV over IP replaces much of that physical routing with a flexible network architecture that can distribute content across rooms, buildings and campuses.

Network-Based Signal Distribution
AV over IP distributes audio and video as data across an Ethernet network.
AV over IP—often shortened to AVoIP—uses Internet Protocol networks to transport professional audio, video and control information between sources and destinations.
Instead of running a dedicated video cable from every source to a central matrix switcher and then another dedicated cable to every display, an AV-over-IP system converts each source into a network stream.
Encoders place video and audio onto the network. Decoders receive the selected stream at displays, projectors, video walls, recording systems or other destinations. Network switches carry the traffic and software or control systems determine which source appears at each endpoint.
Masters Voice Technology designs AV-over-IP systems in Sydney and NSW for corporate workplaces, education facilities, government environments, venues and multi-site digital-signage networks.
AV over IP changes the signal path from a fixed physical route to a managed network route.
The source and display no longer need a dedicated end-to-end cable path through a fixed-size matrix. They need suitable network connectivity, compatible endpoints and a correctly designed AV network.
The Traditional Architecture
Point-to-point AV creates a dedicated physical pathway between equipment.
Point-to-point distribution can be simple and dependable, particularly in a single room. Its limitations become more visible as the number of sources, displays, rooms and required routes increases.
02
Fixed matrix capacity
A matrix switcher has a defined number of inputs and outputs, such as 8 × 8, 16 × 16 or 32 × 32.
03
Dedicated destination cables
Every display or projector requires its own physical connection back to the matrix or source.
04
Centralised rack hardware
Signal switching and extension hardware is commonly concentrated in one main equipment rack.
05
Physical expansion
Adding destinations may require new switcher cards, larger hardware and additional end-to-end cabling.
06
Limited routing boundaries
Signal routes are constrained by the matrix size, installed cable pathways and the physical location of equipment.
This architecture is not obsolete. A direct HDMI connection or small matrix can still be the most practical design for a compact meeting room or simple two-display system.
The challenge arises when an organisation needs to distribute many sources across many destinations or expects the system to change regularly. Physical routing becomes increasingly expensive and difficult to modify.
A More Flexible Distribution Model
Modern organisations need AV systems that can expand and change without rebuilding the entire signal path.
The move to AV over IP is being driven by larger display networks, flexible workplaces, centralised content, campus connectivity, remote management and the increasing convergence of AV and IT infrastructure.
01
Systems need to scale
Organisations want to add new screens, rooms and sources without replacing a fixed-capacity matrix switcher.
02
Spaces change more often
Flexible workplaces, divisible rooms and multi-use venues need routing that can be reconfigured through software.
03
Content is increasingly centralised
Media players, broadcast feeds, digital signage and production sources may need to serve many destinations from one location.
04
AV and IT are converging
Commercial AV systems now rely on network switches, VLANs, monitoring, software management and cybersecurity controls.
05
Support needs better visibility
Networked endpoints can provide device status and diagnostic information that is difficult to obtain from passive cable paths.
06
Buildings need reusable infrastructure
Structured network cabling can support changes more easily than installing a new dedicated video cable for every future destination.
Architecture Comparison
How AV over IP changes commercial video distribution
The difference is not simply the type of cable. AV over IP changes how routes are created, how the system expands and how equipment is managed.
| Design consideration | Point-to-point AV | AV over IP |
|---|---|---|
| Signal path | Dedicated physical cable routes between sources, switchers and destinations. | Encoded streams travel through Ethernet switches to compatible network endpoints. |
| Switching capacity | Limited by the input and output capacity of the installed matrix. | Determined by network capacity, switch architecture, endpoints and management platform. |
| Expansion | May require more cabling, larger matrix hardware or additional switching frames. | New endpoints can often be added by extending the suitable AV network and configuration. |
| Routing changes | Constrained by existing physical connections and switcher capacity. | Routes can be changed through control software without repatching the physical system. |
| Geographic reach | Usually limited by cable distance and the location of the matrix. | Can distribute across rooms, floors and buildings when the network architecture supports it. |
| Troubleshooting | Relies heavily on physical cable testing and access to central hardware. | Combines physical checks with network monitoring, endpoint status and software diagnostics. |
| Best fit | Smaller, fixed systems with limited sources and destinations. | Larger, expanding or frequently changing distribution systems. |
From Source to Screen
An AV-over-IP system combines endpoints, network switching and control software.
Each layer has a defined role. Reliable operation depends on designing the endpoints and network as one complete AV architecture.
01
AV sources
Sources can include computers, media players, television tuners, cameras, signage players, presentation inputs and production systems.
02
Encoders
Encoders convert the source’s audio and video into an IP stream that can be transported across the selected network.
03
Network switches
Managed switches transport the streams and apply the multicast, bandwidth, segmentation and traffic-management configuration.
04
Decoders
Decoders receive the selected stream and convert it back into a signal for the display, projector or other destination.
05
Control platform
The user interface determines which source is routed to each display or group of displays.
06
Management software
Management tools provide endpoint configuration, route control, status visibility and diagnostic information.
07
Audio integration
Audio can remain embedded with video or be separated and routed through a networked audio platform such as Dante.
08
Monitoring and support
Networked visibility can help support teams identify offline devices, failed links and configuration issues.
AV over IP can also be integrated with Q-SYS control and audio processing , Crestron, Extron or AMX interfaces so users do not need to interact with technical routing software.
The everyday interface can remain simple: select the required screen, choose a source and apply the route. The network and endpoint configuration remains protected from normal users.
Grow Without Rebuilding the Matrix
AV over IP allows the distribution system to grow endpoint by endpoint.
A fixed matrix may provide spare capacity at installation, but once that capacity is used the organisation may need a major hardware change. Networked distribution offers a more modular growth path.
01
Add another display
A compatible decoder can be connected at a new destination when network capacity and cabling are available.
02
Add another source
A new encoder can make the source available to authorised destinations across the AV network.
03
Create display groups
Displays can be grouped by room, floor, venue area, operating mode or content requirement.
04
Change routes through software
Content assignments can be updated without physically repatching the system or changing matrix output cards.
05
Support flexible rooms
Divisible rooms and changing event layouts can use presets that alter video routing around the active room configuration.
06
Distribute across facilities
Correctly designed networks can extend content distribution beyond a single rack, room or floor.
AV over IP does not create unlimited capacity.
Expansion still depends on available switch ports, uplink capacity, bandwidth, multicast configuration, licensing, endpoint compatibility and the physical network infrastructure.
AV over IP Is a Networked System
The network cannot be treated as an unspecified cable between AV devices.
Switch selection, bandwidth, multicast management, VLAN design, uplinks, latency, security and documentation all influence whether the system performs reliably.
- Calculate the bandwidth of every expected video and audio stream.
- Confirm whether endpoints require 1GbE, 2.5GbE, 10GbE or higher connectivity.
- Size switch uplinks around aggregate traffic rather than individual port speed.
- Configure multicast management, including IGMP snooping and an appropriate querier where required.
- Decide whether AV uses a dedicated network or a controlled, converged enterprise network.
- Plan VLANs, addressing, Quality of Service and administrative access.
- Document switch configuration, endpoint locations, routes and network ownership.
- Test the complete system under realistic simultaneous traffic conditions.
A network switch is part of the AV system—not a generic accessory.
Some compressed AV-over-IP systems can operate across 1GbE networks, while higher-bandwidth or lower-compression architectures may require 10GbE connectivity and substantially larger uplinks.
Masters Voice Technology provides structured communications cabling and AV network infrastructure alongside AV design, endpoint configuration and system commissioning.
Select the Architecture for the Application
Every AV-over-IP design balances image quality, bandwidth and latency.
There is no single compression method that is best for every project. The correct choice depends on the content, available network, required resolution, acceptable delay and number of simultaneous streams.
Lower Compression
High quality and very low latency
Suitable for interactive applications, control rooms, production and environments where delay must remain extremely low.
- Higher bandwidth requirement
- May require 10GbE infrastructure
- Strong image quality
- Useful for demanding interactive content
Moderate Compression
Balanced quality and network load
Common in commercial distribution systems that need strong image quality and responsive switching across 1GbE or similar networks.
- Reduced stream bandwidth
- Visually strong commercial performance
- Suitable for many workplaces and venues
- Latency varies by platform
Higher Compression
Efficient transport over constrained networks
Useful for digital signage, contribution feeds and applications where modest additional delay is acceptable.
- Lower bandwidth per stream
- Useful across wider networks
- May introduce more latency
- Quality depends on content and codec settings
Resolution alone does not define AV-over-IP performance.
Two systems may both support 4K video while producing different bandwidth, latency, colour accuracy, scaling, switching and image-quality results. The complete application must be assessed.
Different Platforms for Different Workflows
AV over IP is a category—not one universal protocol.
Integrators must evaluate the platform, codec, endpoint ecosystem, interoperability, management software and long-term manufacturer support.
SDVoE
High-performance video distribution
Commonly considered for low-latency, high-quality distribution across enterprise, control-room and large display environments.
Dante AV
Audio and video network integration
Extends the familiar Dante networking approach into video transport and can align with an existing Dante audio environment.
NDI
Production and software-oriented workflows
Common in live production, streaming, cameras, software processing and environments where video must move between networked production tools.
IPMX
Developing standards-based interoperability
IPMX is intended to support open, standards-based professional media transport across interoperable products.
Other proprietary and standards-based solutions are also available. Products should not be selected from the protocol name alone. Consider network requirements, endpoint range, control integration, security, manufacturer support and the expected system lifecycle.
Audio-only environments can also benefit from Dante audio-network design and integration , replacing large point-to-point analogue cable systems with flexible digital audio routing.
High-Value Applications
AV over IP provides the greatest value where content must serve many changing destinations.
The business case becomes stronger as the number of endpoints, buildings, content sources and routing combinations increases.
01
Corporate campuses
Route presentation, town-hall, signage and broadcast content across meeting rooms, training spaces, reception and staff areas.
02
Education campuses
Share learning, event, lecture and signage content between classrooms, halls, campuses and central production facilities.
03
Government facilities
Distribute secure conferencing, operational information, hearing-room content and control-room video between authorised destinations.
04
Hotels, pubs and clubs
Route live sport, digital signage, venue promotions and function-room sources to commercial displays across multiple zones.
05
Control rooms
Deliver operational sources to operator displays, overview walls, monitoring positions and recording systems.
06
Digital-signage networks
Distribute central sources, emergency content and live information to selected screens or screen groups.
Use the Simplest Suitable Architecture
Not every commercial AV project needs AV over IP.
Networked distribution should solve a genuine routing, scale or management requirement. Adding an IP architecture to a simple room can create unnecessary cost and support complexity.
- A single source connects directly to one nearby display.
- The room has a small, fixed number of sources and destinations.
- Future expansion or cross-room distribution is unlikely.
- The client does not have the network capability or support model required for AVoIP.
- A direct, isolated signal path is preferred for the application.
- The network upgrade would cost more than the operational flexibility provides.
- The room can be supported more easily with a small conventional switcher.
Hybrid architectures are common.
A building may use direct connections inside simple meeting rooms while using AV over IP to distribute centralised content between larger training rooms, reception displays, event spaces and digital-signage endpoints.
The best design uses AV over IP where its flexibility creates value and conventional distribution where a direct route remains simpler.
Treat AV Endpoints as Managed Network Devices
AV over IP must align with the organisation’s network and cybersecurity policies.
Encoders, decoders, controllers and management servers are connected devices. They require controlled administrative access, secure configuration, lifecycle management and agreed ownership between AV and IT teams.
01
Network segmentation
Use suitable VLANs or dedicated network architecture to control AV traffic and administrative access.
02
Account security
Replace default credentials, restrict management access and document authorised administrator accounts.
03
Firmware management
Review updates for security, stability and compatibility before applying them across production endpoints.
04
Device inventory
Record model, serial number, location, IP address, switch port, firmware and warranty details.
05
Content protection
Confirm how the platform handles protected media, encryption and authorised source access.
06
Support responsibility
Define which tasks belong to AV support, internal IT, the network provider and the manufacturer.
AV and IT should agree on the network before equipment is ordered.
The project should document bandwidth, switches, VLANs, multicast, addressing, security, remote access, monitoring, backups and responsibility for ongoing network changes.

Design Before Procurement
What to define before selecting an AV-over-IP platform
Begin with routing, quality and operational requirements. Product selection should follow the system design rather than determine it.
01
List every source
Document computers, television services, media players, cameras, signage systems, production feeds and presentation inputs.
02
List every destination
Record displays, projectors, video walls, recording systems, production systems and monitoring positions.
03
Define all routes
Confirm which sources need to reach which destinations and whether simultaneous routes are required.
04
Set quality requirements
Define resolution, frame rate, colour requirements, scaling, protected content and acceptable visual compression.
05
Set latency requirements
Determine whether the application is passive viewing, interactive presentation, live performance, production or control-room monitoring.
06
Assess the network
Review cabling, switches, port speeds, uplinks, PoE, multicast, segmentation, security and available rack infrastructure.
07
Plan the control interface
Decide how staff select sources, screens, groups, presets and emergency content without accessing technical configuration.
08
Plan future growth
Allow for additional endpoints, higher resolutions, new buildings, more source types and changing operating workflows.
09
Define support responsibility
Agree on monitoring, configuration backups, firmware, network changes, warranty support and onsite fault response.
Selecting the right delivery partner is also important because AV over IP sits between professional AV and enterprise networking. Review How to Choose a Commercial AV Integrator before comparing project proposals.
