How much bandwidth Billboard uses

Billboard is light on the network because it doesn't stream your content — each screen downloads your media once, then plays it from the Apple TV itself.

How it uses the network

• On first load, a screen downloads the media in its gallery. A few photos is a few megabytes; a gallery of large videos is more.
• After that, the screen just checks in on the gallery's refresh interval and only downloads what's actually changed — a new photo, a re-crop, a reordered playlist. If nothing changed, there's almost nothing to transfer.
• Playback itself uses no bandwidth — it's all local to the device.

So your data use is mostly a one-off cost each time you change a gallery, not a constant stream. This is a real difference from browser-based signage that re-streams content continuously.

Keeping it light on big fleets

• Set a longer refresh interval on galleries that don't change often — screens check in less frequently. See Customise the display.
• Keep videos a sensible size; see Supported files, sizes and limits.
• Roll out changes when the network is quiet if you're updating many screens at once.

If the network drops

Because content is already on the device, an outage doesn't interrupt playback — see Staying live when the internet drops. For the domains to allow through a firewall, see Network requirements.
