Dynamic Wallpaper¶

What is Dynamic Wallpaper?¶

Dynamic Wallpaper is a feature that automatically activates after a configurable period of inactivity, displaying a collection of images or videos on the screen. It serves the following purposes:

Creating a JSON File¶

Follow these steps:

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

Image and Video Collection¶

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

Note

{
   "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 Presentation",
        },                 
    ],
    "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.

Note

Only .MP4 and .JPG file formats are supported.

{
   "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.

Contents on a USB Stick¶

Our sample file wallpaper_file.json for contents on a USB stick is available for download.

Note

Only the file formats .MP4 and .JPG are supported.

{
   "slideshow": [
        {
         "image_url": "/media/usb0/pic1.jpg",
         "attribution": "Test Picture 1",
         "duration": 10,
        },
        {
         "image_url": "/media/usb0/pic2.jpg",
         "attribution": "Test Picture 2",
         "duration": 10,
        },
        {
         "url": "/media/usb0/video1.mp4",
         "title": "QuattroPod USB - Next-Generation Wireless Presentation",
        },                 
    ],
    "next": ""
}

Save the file as wallpaper_file.json along with the image and video files in the root directory of a USB stick.

Insert the USB stick into the USB port of the receiver. The USB LED will light up white.
