Integrating Multiple AV over IP Protocols in a Hybrid AV System

As audiovisual technology advances, more organizations are turning to AV over IP solutions to manage and distribute audio, video, and control signals across their spaces. AV over IP makes it possible to create flexible, scalable, and cost-effective systems by leveraging standard network infrastructure. However, in many cases, a single AV over IP protocol does not meet all the requirements of a complex installation. This is where hybrid AV systems come into play. By integrating multiple AV over IP protocols, integrators can design systems that combine the strengths of different technologies to achieve optimal performance. In this blog, we explore how hybrid AV systems work and what you need to know about integrating multiple AV over IP protocols.

What Is a Hybrid AV System

A hybrid AV system combines different technologies, protocols, or transmission methods within a single AV environment. The goal is to take advantage of the unique benefits offered by each protocol or technology and to address the specific needs of various parts of the system. For example, you might use one AV over IP protocol for high-resolution video distribution to large displays and another protocol for low-latency audio feeds to conferencing endpoints. The key to success is ensuring these components work together seamlessly.

Why Integrate Multiple AV over IP Protocols

There are several reasons why you might choose to integrate multiple AV over IP protocols in your design:

Different performance requirements: Some parts of your system may require ultra-low latency, while others prioritize high image quality or efficient bandwidth usage.
Legacy system integration: Many installations must support existing AV hardware that uses different protocols.
Cost efficiency: Certain protocols or hardware solutions might be more affordable for specific applications.
Flexibility for future expansion: A hybrid approach gives you the freedom to incorporate new technologies as your needs evolve.

By mixing protocols, you can design a system that is tailored to the specific goals and constraints of your project.

Examples of AV over IP Protocols in Hybrid Systems

There are many AV over IP protocols in use today, each with its own strengths. Some common examples you may see integrated in a hybrid AV system include:

H.264 / H.265: These are widely used video compression standards that offer good quality at relatively low bitrates, suitable for streaming over wide-area networks.
JPEG 2000 or JPEG XS: These codecs are known for visually lossless compression with low latency, ideal for high-end applications like broadcast or live events.
Proprietary AV over IP protocols: Some manufacturers offer their own AV over IP protocols designed for specific hardware ecosystems, offering tight integration and optimized performance.
Uncompressed AV over IP standards: Protocols like SMPTE ST 2110 support uncompressed or lightly compressed video for applications where absolute fidelity and minimal latency are critical.

When planning a hybrid system, it is important to understand how these AV over IP protocols can complement each other.

Key Design Considerations for Integrating Multiple Protocols

When you design a hybrid AV system that uses multiple AV over IP protocols, there are several factors to keep in mind.

1. Network Infrastructure Compatibility

Different AV over IP protocols place different demands on the network. For example:

Protocols that transmit uncompressed or lightly compressed video require much higher bandwidth than highly compressed streams.
Some protocols rely on multicast, while others use unicast.
Your switches and routers must support the necessary features such as IGMP snooping, VLANs, and Quality of Service (QoS).

Before you begin integrating multiple AV over IP protocols, ensure your network infrastructure can handle the combined load and feature requirements.

2. Signal Conversion and Bridging

When different protocols are used in the same system, you may need devices that can act as bridges or converters between them. Examples include:

Gateways that convert compressed AV over IP streams into baseband video for legacy equipment.
Multi-format receivers that can decode different stream types.
Hardware or software solutions that transcode between codecs in real time.

These bridging devices are essential to ensure that signals can move smoothly across different parts of your hybrid AV system.

3. Latency Management

When combining AV over IP protocols, it is important to manage latency carefully. Different protocols introduce varying amounts of delay due to their compression methods, network handling, and processing. If not accounted for, these differences can lead to synchronization issues, especially between audio and video or between different displays.

Design your system so that latency is balanced across the various components, or use delay compensation tools where necessary.

4. Centralized Control and Monitoring

A key challenge in hybrid AV systems is managing multiple protocols from a single interface. Where possible:

Choose control systems that can integrate with all components of your hybrid system.
Use network management tools that monitor all AV over IP protocols on your network.
Standardize documentation so that your team can easily troubleshoot and maintain the system.

Centralized control makes the hybrid system feel seamless to the user and simplifies maintenance over time.

5. Security Considerations

AV over IP systems are part of your broader IT infrastructure and must be secured properly. When using multiple AV over IP protocols:

Ensure all components support encryption where required.
Use VLANs or separate physical networks to isolate AV traffic.
Work closely with IT teams to align the AV system with organizational security policies.

Best Practices for Success

Here are a few tips to make your hybrid AV system a success:

Plan early and involve both AV and IT teams in the design process.
Document all protocols, endpoints, and network configurations clearly.
Test compatibility between protocols and bridging devices before full deployment.
Design for scalability so that you can easily add new protocols or technologies as needed.
Provide training for operations teams on managing and troubleshooting the hybrid system.

Conclusion

Integrating multiple AV over IP protocols in a hybrid AV system allows you to create flexible, powerful solutions that can meet diverse needs across a facility. With careful planning, the right hardware, and strong collaboration between AV and IT professionals, you can design systems that deliver excellent performance, reliability, and user experience. Understanding the strengths and requirements of different AV over IP protocols is the first step toward building hybrid AV systems that are ready for the future.
