The link to shore is metered, shared with paying guests, and not something a signage estate should be spending.
Several hundred screens per ship, ten to thirty ships, and one satellite link that paying guests are already using. Even on the newest hulls that bandwidth is metered and shared, so an estate that streams its content from shore is competing with the thing guests complain about first. Here the content lives on the ship, the screens compose from it locally, and the link carries decisions rather than media.
The link is metered, shared, and the guests are paying for it. Streaming signage from shore takes bandwidth from the thing guests complain about most. On board, the media is already on the ship, the screens render from it, and what crosses the satellite is a declaration of what should be showing, which is a few kilobytes rather than a few gigabytes.
A ship is out of reach. Nobody is flying an engineer to a vessel mid-Atlantic. Every screen reports its own storage, memory, temperature and whether it is actually rendering, so a failure is a work order for the next turnaround rather than a discovery made by a guest.
The fleet must look like one brand and no two ships are alike. Deck plans, venue names and the number of screens differ hull to hull. The brand and the program are fleet level, the deck and the venue are the ship’s, and a newly delivered vessel joins with the fleet’s content already on it.
Video is the point at sea, not an extra. The safety video before sailing, the destination film for tomorrow’s port, the show trailer that fills the theatre, the training that has to reach every crew member. All of it plays from the ship at full rate, and the satellite is never in the path when it matters.
Media resident on the ship. The shore link carries decisions, not files.
Safety override on every screen at once, in multiple languages, with a render receipt from each screen.
Zones for guest areas, crew areas, venues and bridge, each with their own rules.
Works with the link degraded or down. A screen keeps showing the right thing and catches up when the ship is back in coverage.
One license covers signage, casting into conference and meeting rooms, and priority messaging.
Adapters bought outright at $50 each, so the hardware sails with the ship rather than being rented.
None of the above is a playlist somebody maintains. Each screen is a surface for Ava, which holds one understanding of the place and knows which room it is in, so what belongs there at that hour is composed rather than authored. A muster list and a daily program are enough for her to run a vessel that never touches shore-side software.
Four hundred screens a ship across twelve ships is four thousand eight hundred screens. At $40 per screen per year with the hardware owned, put that against what the fleet pays today per vessel, per system, per renewal.
