Are you looking for a way to push custom content to every screen in your venue? Whether hotel, stadium or hospital… Large venues require a reliable method to broadcast content to hundreds, if not thousands, of screens. But most are turning to one time-tested solution.

An RF based broadcast video distribution system.

Wait… What?

RF modulation isn’t cutting edge technology. In fact, it’s been powering venue-wide video distribution for decades. It works by encoding digital video sources (HDMI/SDI signals) as RF that can travel over existing coax cable to any connected display.

Simple. Easy to scale. And it works.

In this article you’ll discover

• Exactly How RF Modulation works
• Why Coaxial Distribution Is Still King
• Who Is Using This Tech
• Plus, How to Choose The Right System

How RF Modulation Works For Large Venues

RF Modulation. It sounds complex. But the process is actually quite simple.

A modulator encodes video sources (media players, camera feeds, set-top boxes, etc.) as RF channels. These channels are then sent through coax cable to every screen or display on the system.

Each screen tunes into the appropriate channel to receive the content. Think cable TV. But instead of Comcast controlling the channel lineup… You do. Companies like Thor Broadcast have built careers around designing broadcast video distribution system solutions that allow venues to do just that. Broadcast capable modulators and encoders allow any source to be distributed across coaxial cable networks to create custom channel lineups playing HD or 4K content.

Sounds pretty great right?

And because every screen shares the same source… There’s no need for individual media players at every display. This not only makes the initial install a lot quicker, but greatly reduces hardware costs for venues who need to scale.

Why Is Coaxial Distribution Still So Popular?

If you’ve been reading articles about digital signage and venue tech lately… You’ve probably heard a lot about IP video and streaming solutions.

With all of this focus on new technology… You may be wondering why coaxial cabling is still so dominant in large venue situations.

Here’s why.

The majority of large venues already have coax installed. Hotels, hospitals, stadiums, universities… You name it. Chances are it’s already inside the walls. Demolishing that infrastructure to replace it with ethernet cables is costly and time consuming.

RF distribution allows those venues to use what’s already in place. No new wiring. No complicated network setups. Just connect and distribute.

It’s a trend that’s expected to continue as well. The global market size for broadcast equipment (encoders, modulators, transmitters, etc.) was valued at $5.35 billion in 2024 and is projected to grow by 7.7% annually through 2030. Venue owners are investing in this technology because it just works.

The benefit doesn’t stop there either…

It’s reliable. There’s no dependence on network connectivity. When you use RF distribution, you don’t have to worry about buffering, low bandwidth from overuse or an entire network failing and taking every screen with it. The content is fed through the coax straight to the display.

Which is a huge deal when your venue relies on uptime. Hospitals need to be able to broadcast emergency information at a moments notice. Stadiums can’t have screens go black in the middle of a broadcast.

Who Uses Broadcast Video Distribution Systems?

Video distribution systems are used in just about every major venue. Anyone who needs to push content to a large number of screens at the same time.

Below are just a few examples:

Hotels. Want to give guests access to custom content in their rooms? RF modulation allows hotels to build a unique channel lineup for each room that plays right into the TV from the hotel’s headend. Want to know what kind of impact this has? 70% of guests report digital signage and in-room video keeps them engaged while staying at a hotel.

Stadiums. Streaming live camera feeds to displays around the concourse? Showing important replays on the big screens? Digital signage promoting club sponsors? RF modulation makes it possible to broadcast to every screen at the same time.

Hospitals. Patient rooms, waiting areas and staff break rooms all require different content. RF allows hospitals to securely distribute entertainment channels, health information programming and emergency alerts anywhere in the building from a single location.

Universities. Every TV in student dorms, lecture halls and common areas can access a campus wide DVR and broadcast system thanks to RF modulation.

Prisons. Correctional facilities have used RF systems for years to control what inmates can watch on TV. Channel lineups can be restricted to meet facility standards and ensure inmates aren’t able to access banned channels.

These are just a few examples of the types of venues that can benefit from this technology.

Choosing The Right System For Your Venue

Every venue is going to have different needs when it comes to a broadcast video distribution system. A school isn’t going to need the same setup as a stadium. Here are a few things to think about before making your decision.

Inputs. What formats does the venue need to support? HDMI? SDI? IP streams? Make sure you get a modulator that accepts the signals you’ll be distributing.

Channel Needs. How many channels does the venue actually need? Some venues will only need 1 or 2 channels for basic playback. Hotels usually have anywhere from 10-20 channels to offer guests a nice variety of content.

Video Resolution. At a minimum you’ll want a system that supports 1080p HD. But 4K is becoming more popular these days as well. Especially since higher-quality videos hold viewers attention longer.

Encoding Format. Video needs to be encoded properly before it can be broadcast on a channel. H.264 is the standard encoding solution, but H.265 is rapidly gaining popularity. Both offer great compression rates, but H.265 does so with better picture quality at smaller file sizes. More channels can be packed into your coaxial bandwidth with H.265 encoding.

Scalability. Can the system grow with the venue? Is it easy to add new channels or connect new screens? A good video distribution setup should be flexible enough to accommodate growth.

Considering these things will help you narrow down the options and find the perfect setup for your venue.

Conclusion

RF Modulation is here to stay. As long as there are large venues that need to distribute content to multiple screens… RF will be used to power those systems.

It’s easy to install, highly reliable and can scale from small venues to the largest stadium in the world.
