Dynamic Wallpaper¶

What is a Dynamic Wallpaper?¶

The dynamic wallpaper 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 function
Advertising purposes in stores
Public display / Digital Signage

Creating a JSON File¶

Proceed as follows:

Open Windows Notepad (or another text editor) and create a new empty file.
Copy the JSON text blocks into the text editor found below and modify the content as you wish. 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.

Note

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

{
   "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 - Kabelloses Präsentieren der nächsten Generation",
        },                 
    ],
    "next": ""
}

A Minimal Start Page¶

By default, many network and device-related details are displayed:

These can be completely hidden using the dynamic wallpaper, showing only the device name above your image file:

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

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

Note

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

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

    ],
    "next": ""
}

To ensure that only the device name or room number is displayed, the following additional configuration change should be made:

Disable the SoftAP

This completely removes the PSK, i.e., the displayed password of the SoftAP, from the screen.

Content on a USB Stick¶

Our sample file wallpaper_file.json for content 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 Presenting",
        },                 
    ],
    "next": ""
}

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

Plug the USB stick into the USB port of the receiver. The USB LED lights white.
