How do you calculate the number of video outputs for an event?

I start with the destinations, then work backward to the equipment.

Write down every place that needs a video signal. Next to each one, describe the content, resolution, frame rate, and whether that feed needs independent control.

The distinction I want to make is this: the number of screens is not necessarily the number of outputs.

Two monitors showing the same program in the same format may share one output through suitable distribution. A confidence monitor showing presenter notes and a green room monitor showing the camera program need different feeds.

It works the other way, too. One large LED wall may need several separately mapped processor feeds. The audience sees one screen, but your system has to generate multiple outputs to fill it.

Once those requirements are clear, I can look at spare capacity and the backup plan. That gives us a much more useful number than counting the screens on a floor plan.

Build a complete video destination list

The main screen is easy to remember. I want the list to include the destinations that are easier to overlook:

• LED processor inputs for the main wall and scenic LED elements.
• Projectors, including individual regions of a blended image.
• Side screens showing cameras, slides, or separate content.
• Confidence monitors for current slides, next slides, notes, or timers.
• Program recordings and separate clean recording feeds.
• Streaming and overflow-room feeds.
• Backstage, stage manager, and green room displays.
• Operator monitoring, including dedicated multiviewer connections where applicable.

For each feed, I also want to know which device is producing it. A notes feed might come directly from a presentation computer. Another feed might originate at a camera switcher or routing system.

We need to account for the whole show, but we should not charge every destination against the screen manager if another device is actually doing that job.

Example: How a show can reach 14 outputs

Here is a planning example that shows how quickly the count can grow. Assume each line below needs the listed number of separate outputs from the screen management system.

That is fourteen outputs, even though an audience member might describe the room as one LED wall and two projection screens.

This is an example, not a claim that every show needs fourteen outputs. If some destinations can share a feed, the count can come down. If the LED mapping changes or more rooms need their own content, it can go up.

The point is to do this work before choosing the system.

Outputs, connectors, screens, and layers are different specifications

When I compare systems, I want to be sure we are counting the same thing.

An output connector is a physical connection. Several connectors can carry copies of the same processed signal. More sockets do not automatically mean more independently controlled feeds.

An independent output is a separately generated video feed.

A screen or canvas is the display area being managed. One canvas may span several outputs.

A layer is an element within the image, such as a camera window over a presentation background. A system can have enough outputs and still need a closer look at the layer requirements for the show.

My next questions are about what each destination needs to do. Does it need its own composition? What transitions are required? Which resolutions and frame rates are involved? Where are we scaling or converting the signal?

The output count gets us started. Those details tell us whether the system can deliver the actual show.

PIXELHUE Q8 and Analog Way Aquilon output capacity

The PIXELHUE Q8 is worth looking at when the output list starts getting long. PIXELHUE specifies up to 16 concurrent 4K outputs through four output cards. That puts substantial output capacity in one device.

Analog Way publishes 16 active 4K60p outputs for the Aquilon RS4 and 20 active 4K60p outputs for the Aquilon RS6.

Those totals are a starting point. I still want to confirm the installed configuration, screen and auxiliary assignments, and available processing resources. I would not promise that every output can perform every function in every configuration.

For a useful comparison, put your destination list beside the proposed configuration and assign the feeds one by one. Confirm the layers and formats at the same time.

Can you link screen management systems for more outputs?

You can expand some systems, but I would not put “double the outputs” on a proposal without checking exactly how that expansion works.

Analog Way offers Aquilon linking, with specific hardware and card-slot requirements. Those requirements matter when you calculate the usable outputs in the linked system.

PIXELHUE documents control of multiple switchers from one controller or PixelFlow project. That is useful, but controlling two units together is not, by itself, proof of how sources are shared or how the complete system is synchronized.

Before we quote the expanded system, I want the technical team to confirm the link hardware, software, source distribution, synchronization, and final usable output count. The expansion plan should be as specific as the original output map.

Common mistakes when choosing a presentation switcher

Counting only what the audience sees. Put presenter monitors, recordings, and backstage feeds on the first list, not the last one.

Giving every monitor its own output automatically. If several destinations need the same signal, suitable distribution may be the right answer.

Assuming everything can share program. A presenter reading notes needs something different from a guest watching in the green room. Find out what each person needs to see.

Choosing by output count alone. Check the resolution, frame rate, layers, bandwidth, connections, and synchronization that go with those outputs.

Calling a spare output a backup system. A spare gives you flexibility. It does not keep the show running if the processor generating all the feeds fails. Decide what must survive a failure and design the backup path around that requirement.
