Digital Signage App is a web application for playing a media playlist (images/videos) linked to a specific Digital signage item. In CUE Admin, under Applications -> Digital Signage App, you manage individual instances of this application (URL, Digital signage binding, CUEunit display and side LED behavior, licenses, assignment to unit / unit client).

## Usage Modes and Licensing

1. **Standalone URL in a web browser**  
Requires a Digital Signage App license. For third-party devices (outside CUEunit), the corresponding Third-party device licensing is also required.
2. **In CUEunit**  
Only a Digital Signage App license is required.

## What It Is Used For

- Linking a web app instance to a specific Digital signage content source.
- Playing a media playlist (images/videos) in the order defined in [Digital signage](https://cue.atlassian.net/wiki/spaces/TAM/pages/1469579303).
- Configuring CUEunit behavior (display + side LED) for the given instance.
- Assigning the instance to a specific CUEunit or unit client.

## Where the Settings Take Effect

  - availability of selected Digital signage configuration and media,
  - device permissions (unit / unit client).
