Glossary of terms
Start with these four. Everything in impressBox is built from four ideas — learn these first (full picture in Welcome to impressBox):
Device — a physical screen running the player.
Content — one piece of media (image, video, URL, template…).
Playlist — an ordered list of content that loops on a screen.
Schedule — when a screen is on, and when content may play.
The rest of this page is an A–Z reference — dip in when you meet a new word.
Activation code — A 6-digit code shown on a screen during setup. You enter it in the app to connect that screen to your account.
Beanstaller — Remote installation of the player app on LG webOS TVs.
Content category — A folder for organising content in your library.
Content / content item — A single piece of media: image, video, audio, YouTube video, Canva design, or template instance.
Device (player) — A physical screen running impressPlayer.
Device identifier — A device's unique code (e.g. 008MACE52091). Used when targeting a device for publishing. Unlike the name, it is always unique.
Device name — A human-friendly label (e.g. "Reception TV"). Names can repeat.
Device tag — a group of screens you assign so you can act on them together (e.g. by location or screen type), managed in Tag management. Distinct from a content category, which organises media.
Display schedule — A recurring rule that turns a screen on and off at set times.
Emergency playlist — A designated playlist that can override normal playback at a forced volume.
HTML overlay — Custom web content layered on top of what's playing.
impressPlayer — The player software installed on a screen.
Interval grid — A repeating on/off schedule for a content item (play X, pause Y, repeat).
Outpainting — AI that extends/reshapes an image to fit a screen's aspect ratio.
Playlist — An ordered list of content that plays on a screen.
Publish — Send a playlist to one or more devices for playback.
Running line — A scrolling text banner shown along the screen, over the current playlist.
Scheduled publish — Publish a playlist automatically at a future date/time.
Synchronized playback (master/slave) — Several screens playing in step; one master drives the timing.
Template — Content with fill-in fields — a menu or a price board, for example — that impressBox turns into a picture or a video for the screen.
Trash bin — Where deleted content goes; can be restored or permanently removed.
