As the audio visual industry continues to evolve, the shift from traditional AV systems to network based solutions is accelerating. AV over IP has quickly become the preferred architecture for many integrators, designers, and end users. This approach allows audio, video, and control signals to travel over standard network infrastructure rather than dedicated cabling. At the heart of these systems are AV over IP protocols, which define how data is packaged, transmitted, and managed across the network. To future-proof your AV installations, it is essential to understand the emerging AV over IP protocols and how they can help your system stay relevant and capable in the years ahead.
Why AV over IP Is the Future of AV
The advantages of AV over IP are clear. It offers greater flexibility, scalability, and cost efficiency compared to legacy AV systems. With AV over IP, it is easy to add new sources and displays without major rewiring or hardware changes. Content can be routed anywhere on the network, making multi-room and multi-site installations simple to manage. Additionally, as network speeds increase and infrastructure improves, AV over IP systems can scale to handle higher resolutions, new formats, and more complex applications.
However, not all AV over IP systems are created equal. The protocols that power these systems vary widely in terms of performance, features, and suitability for different use cases. Understanding these protocols is key to making choices that will stand the test of time.
What Are AV over IP Protocols
AV over IP protocols define the rules for how audio visual data is transmitted over a network. They cover aspects like compression, latency, resolution, synchronisation, and control integration. Common examples include SDVoE, NDI, Dante AV, JPEG 2000 based systems, and newer options like JPEG XS. Each of these protocols offers unique benefits and is designed to address different priorities, such as video quality, network efficiency, or low latency.
By selecting the right protocol, you can ensure that your AV system meets current needs while remaining adaptable to future technologies.
Key Emerging AV over IP Protocols to Watch
Let us take a look at some of the emerging AV over IP protocols that are helping integrators build future-proof systems.
1. JPEG XS
JPEG XS is gaining attention as a next-generation compression standard for AV over IP. It offers visually lossless quality at low compression ratios while delivering ultra-low latency — often measured in microseconds rather than milliseconds. This makes JPEG XS ideal for live production, medical imaging, military applications, and other use cases where image integrity and speed are critical.
Unlike traditional codecs, JPEG XS is designed for real-time transport over IP networks without introducing significant delay or compromising quality. It is also suitable for 4K, 8K, and HDR content, making it a strong candidate for future high-resolution workflows.
2. Dante AV
Dante is already a widely used standard for networked audio, and with Dante AV, the same level of simplicity and reliability is now available for video. Dante AV integrates audio, video, and control over a single network with tight synchronisation. Its compatibility with existing Dante audio devices makes it attractive for projects where high quality audio and video need to work together seamlessly.
Dante AV supports visually lossless video and can operate over standard 1 Gbps networks, making it a cost-effective option for many applications. It is well suited for conference rooms, houses of worship, and education environments that value ease of integration and management.
3. SDVoE
The Software Defined Video over Ethernet (SDVoE) protocol continues to evolve, offering uncompressed or lightly compressed video at very low latency. SDVoE systems typically run over 10 Gbps networks, delivering exceptional image quality that is suitable for demanding applications like command centers, broadcast studios, and high-end corporate installations.
As network speeds increase and 10 Gbps switches become more affordable, SDVoE will remain a strong choice for future-proof AV designs that require uncompromised quality and flexibility.
4. NDI
Network Device Interface (NDI) is a protocol developed for broadcast and live production but is increasingly used in other AV applications. NDI offers high-quality compressed video over standard networks and is known for its ease of use in software-based workflows. NDI’s low bandwidth requirements and growing ecosystem of compatible tools make it a valuable option for hybrid AV and streaming environments.
Factors to Consider When Choosing Emerging Protocols
To future-proof your AV installation, you should carefully consider the following factors when evaluating AV over IP protocols:
-
Scalability: Choose a protocol that allows you to expand your system as your needs grow. The ability to add sources, destinations, and new formats without replacing core infrastructure is key.
-
Latency: Applications like live events or video conferencing require protocols with minimal delay. Make sure your chosen protocol meets these demands.
-
Video quality: High resolution and HDR support are becoming standard. Ensure your protocol can handle current and future content formats.
-
Network compatibility: Select a protocol that works with your existing network or planned upgrades to minimize costs and complexity.
-
Integration: Look for protocols that integrate easily with control systems, automation, and other building technologies.
How to Future-Proof Your AV System
Here are some practical steps to help you build AV systems that are ready for tomorrow’s challenges:
-
Design with headroom: Use network infrastructure that can handle higher bandwidth than you currently need.
-
Choose protocols with strong industry support and a clear roadmap for updates and enhancements.
-
Build modular systems so that components can be upgraded without replacing the entire installation.
-
Stay informed about evolving standards and best practices in AV over IP design.
Final Thoughts
The world of AV over IP protocols is dynamic and constantly evolving. By understanding the emerging protocols and how they align with your application, you can make smart choices that extend the life of your AV system and deliver superior performance. Whether you are planning a new installation or upgrading an existing system, a future-proof strategy starts with informed protocol selection.
AV over IP offers unmatched flexibility and scalability, but the protocol you choose will determine how well your system adapts to future needs. Take the time to explore your options, and you will be well positioned to build AV solutions that meet the demands of today and tomorrow.
