How an advertisement reaches a moving bus

One content library

Every advertisement in the network lives in one place. Campaigns are assembled there: which creative, which routes, which dates, and how often it should come round.

Nothing is copied onto a memory card and carried to a depot. That is the difference between a handful of screens and a network you can actually operate.

4G and 5G to the vehicle

Each bus carries a mobile data connection. New content and schedule changes are pushed down to the player over that link, so a campaign can start, change or stop while the fleet is out on the road.

A media player on the bus

Behind the screen sits a small computer holding the playlist. It keeps its own copy of every file it needs, and that local cache is the part that makes the system dependable.

Mobile coverage along a bus route is never continuous. There are tunnels, dead pockets and congested cells. Playback cannot be allowed to depend on any of that.

Playback in the cabin

The screen runs through the operating hours of the vehicle, following the schedule set in the cloud: what plays, in what order, and how often each item repeats.

Your advertisement on the route

Your creative plays to the passengers on the routes you booked. Because the route is fixed and the timetable repeats, the same commuters see it on the way home, and again the next morning.

A record that comes back

The player records what it played and when, and reports that back. Screens report whether they are online.

That record is what turns a campaign from a promise into something checkable. It also means a fault is usually visible to us before it would be noticed anywhere else.
