Docs Getting started
Core concepts
Organisations, media, slides, playlists, screen groups, schedules and publishing — the words used everywhere else in these docs.
Organisations
Info Display has three levels:
| Level | Who it's for | Examples |
|---|---|---|
| Platform | The Info Display service itself, run by us. | — |
| Company | An account that manages one or more clients and sets their quotas. | A signage agency, a franchise head office, a school district |
| Client | Where the actual work happens: content, screens and the people who edit them. | One café, one office, one school |
Most small teams have exactly one company with one client and never need to think about this. Agencies create a client per customer, so every customer's content, screens and people stay separate.
Media
Photos and videos you've uploaded. Images are converted to WebP in a display size and a thumbnail; videos are converted to H.264/AAC at up to 1080p with a poster frame, so every screen can play them smoothly. Media belongs to a client and counts towards its storage quota.
Slides
A slide is one thing on screen for a while: an image, a video, a YouTube video, a web page, text, custom HTML or a clock. Every slide has a duration (or until the video ends), a transition and can be temporarily disabled. See slides for all types and options.
Playlists
An ordered list of slides that plays on a loop. The same slide can appear in several playlists, and a playlist can override how long a slide stays on screen.
Screen groups
A set of screens that play the same content — Lobby, Menu boards, Corridor. A group has an orientation (landscape, portrait, or either one flipped), a default playlist and optionally schedule rules.
Schedule rules
A rule says play this playlist on these days, between these times, within these dates. When several rules match, the one with the highest priority wins. When none match, the group plays its default playlist. See schedule rules.
Publishing
Edits are drafts. Publishing takes a snapshot of each screen group — its playlists, slides, schedule and media — and turns it into a manifest: an immutable, content-addressed description of what to play. Screens fetch the manifest, download any media they don't have yet, verify it and only then switch over.
Because the manifest is a snapshot, you can keep editing without screens changing under you. Publishing unchanged content does nothing.
Screens (devices)
A physical display running the Info Display agent. Each screen is paired to one client and belongs to one screen group. Pairing uses a slot from the client's device quota; unpairing frees it again.
Roles
People get a role per company or client: viewer, editor, client admin or company admin. See people and roles.
