Dynamic Background Image¶

What is a Dynamic Background Image?¶

The dynamic background image is a feature that automatically starts after a configurable period of inactivity and displays a collection of images or videos on the screen. It serves the following purposes:

• Screensaver functionality
• Advertising purposes in stores
• Public Display / Digital Signage

Creating a JSON File¶

Follow these steps:

• Open Windows Notepad (or any other text editor) and create a new empty file.
• Copy the JSON text blocks, which can be found below, into the text editor and modify the content as desired. For additional entries, copy the sections enclosed in curly braces {} as often as needed.

JSON Syntax¶

• image_url The path to the image file.
• attribution The title of the image file.
• duration The display duration of the image file.
• url The path to the video file.

Image and Video Collection¶

Our sample file wallpaper_file.json for the image and video collection is available for download.

{
   "slideshow": [
        {
         "image_url": "https://download.stueber.de/doc/de/content/pic1.jpg",
         "attribution": "Test Picture 1",
         "duration": 10,
        },
        {
         "image_url": "https://download.stueber.de/doc/de/content/pic2.jpg",
         "attribution": "Test Picture 2",
         "duration": 10,
        },
        {
         "url": "https://download.stueber.de/doc/de/content/video1.mp4",
         "title": "QuattroPod USB - Next-Generation Wireless Presenting",
        },                 
    ],
    "next": ""
}

A Minimal Landing Page¶

By default, numerous network and device-related information is displayed:

You can completely hide this information using the dynamic background feature, displaying only the device name over your image:

We recommend renaming the device to match the room number, as shown in the screenshot above.

Our sample files wallpaper_file.json and example.projector.pptx for the minimal landing page are available for download. The .pptx file can be customized in Microsoft PowerPoint and saved as a .JPG file.

{
   "slideshow": [
        {
         "image_url": "https://download.stueber.de/doc/de/content/example.projector.jpg",
         "attribution": "",
         "duration": 10,
        },

    ],
    "next": ""
}

To ensure only the device name or room number is displayed, make the following additional configuration changes:

• Disable the SoftAP

This will completely remove the PSK (the displayed SoftAP password) from the screen.

How to Set Up the Dynamic Background Image¶
