AV-over-IP vs Traditional Matrix Systems

In today’s AV world, there is a landscape of great options when it comes to choosing a professional video system. If you’re looking to create a bullet proof video distribution system there are two major options to choose from. AV over IP and a traditional matrix. Each has their own strengths as well as weaknesses so let’s go ahead and look at them both so that you are better equipped to make an informed decision. 

What Is a Traditional Matrix System?

A traditional matrix system is a tried and true piece of hardware that has earned its place in the world of pro AV. These are dedicated hardware boxes that route video signals from multiple inputs to multiple outputs using traditional video delivery cables like HDMI or SDI. 

Typically it’s normal to see an HDMI matrix in most installs and they’ll generally be used to deliver signals from cameras, computers, cable boxes and more to several displays. Generally you’ll see them installed in a centralized equipment rack. 

What Is AV-over-IP?

AV over IP takes a bit of a different approach to the same problem. Instead of using a large box that is limited to the amount of inputs and outputs and utilizes cables like HDMI, it instead delivers video over a standard Ethernet network. 

You will generally have encoders, decoders and sometimes controllers in these setups. The encoders take the signals and convert them to a data signal that can be transported over the network. The decoders translate those signals back to a signal that can be sent out into the displays through standard cables like HDMI. 

Key Differences

Scalability

As mentioned, a normal matrix switcher is always going to be limited to the amount of inputs and outputs it was designed to have. You can’t add more to that unit itself, you will either need to introduce a new unit and potentially daisy chain or simply replace it entirely with a more fitting size. 

AV over IP however works a bit differently. Since these systems are separated into encoders and decoders, you can expand when you find it necessary and can have a flexible system. You can do this up to the limitations of the specific system or network you are working with. 

Cable Distance

Matrix systems typically will rely on HDMI or SDI cable limitations. This means that you might need extenders for long runs or that you invest in a specifically designed matrix that utilizes HDBaseT or CAT cable and receivers. 

AV over IP is designed to use standard network infrastructures, which makes it easier to cover larger buildings or campuses.

Flexibility

AV over IP is going to offer the most flexibility to users, but it doesn’t come for free. Because these can be placed anywhere within the network it offers a lot of room for both install and expansion. That being said, AV over IP systems are both reliant on your network and can be more expensive than a traditional matrix. They do however offer some extra benefits as well as some models can give video wall and multi-viewing functionality on top of being a matrix. 

Traditional matrix systems are simpler but generally offer less options for install and expansion for more complex environments.

Cost Considerations

If you don’t need to expand your systems, don’t have a robust network or know exactly how many inputs and outputs you need, a traditional matrix can be the most cost effective way to tackle your needs. Generally these will be a sizable amount cheaper than AV over IP systems to build. 

If you’re looking to create a system that is easily expandable and don’t mind paying more for the flexibility and the convenience of being able to deliver video anywhere there’s an Ethernet port that is on the same network, then AV over IP is likely worth the extra spend. 

Which One Should You Choose?

Choose a traditional matrix system if:

• The installation is small and unlikely to grow
• Cable runs are short
• Simplicity is the top priority

Choose AV over IP if:

• The system may expand over time
• Long-distance routing is required
• Multiple rooms or buildings need shared video access
• Flexibility and scalability are important

Final Notes

As we continue to create robust networks, AV over IP will continue to carve a place out for itself in the pro AV market. However that doesn’t mean that traditional matrix systems are obsolete or worse than AV over IP. It all comes down to what your use case is and what you need the system to achieve.
