Each Resource Group in the Userful Control Center has a number of toggle functions associated with it. Most of these are disabled by default.
Default Mapping: Newly paired displays or created zones will be assigned to this Resource Group
Show Welcome Screen: When this functionality is enabled, instead of running the first source in the list, the display or zone shows a Welcome Screen where a user must select a source to start. It is mostly used for Public Computing and interactive kiosks.
Tile Mode: It converts the Welcome Screen into a more touch-friendly tiled arrangement, with customization options for branding and color. It is a great feature for Public Computing, interactive kiosks, and many other use cases.
Control Center: Enables/Disables the link to the Userful Control Center on the welcome screen.
Rotate Sources: When this option is enabled and more than one source exists in the Resource Group, a Zone that is stopped and started will then play the next source down the list.
Mirror Group: It enables a Mirror Group.
It is a great way to customize and brighten the look of a welcome screen for public kiosks. The tile welcome screen can have colors, logos, and text customized for your needs.
Customizing the welcome screen will also set the same colors for the source switcher.
Tile Mode: It turns the Tile Welcome Screen On or Off
Header: It is the very top section of the image below, and you can upload a custom image file to serve as your company logo in the top-left corner of the screen, and also set text, along with background and text colors for the title in the top-right corner.
Sources:
This by default uses white text over a color palette selected from a default set of colors. You can select a color for the text, and then add one or more HTML color codes to create your own palette.
For example,
The color codes #c000f5, #0008f5, #ff0000, #01b70d creates screen arrangements like the image shown below.
Enable the Date and Time function to show the clock on the screen, and Language Selector to allow users to switch the interfaces and their logged-in sections to their own language.
Finally, you can alter the background color to fit your theme.
Click on any source icon to launch the selected source on the display or video wall.
Each source/plugin can have its own set of icons that can be placed in the directory path /usr/share/userful-plugin-<plugin-name>/icons. root privileges are required throughout this procedure. Changes will not take effect until the Userful server is rebooted.
The source icons can be changed by clicking on the existing icon while configuring the source in Mapping.
A Mirror Group is a single tool that has multiple benefits.
The primary function is to enable perfect synchronization of content across multiple displays and/or Zones. Mapping multiple displays or Zones to a source without a Mirror Group has a few different side effects based on the type of Source.
Interactive Sources will start multiple instances of their respective applications
Direct Sources will attempt to play the same content files or streams multiple times. At best this results in out-of-sync playback, at worst it can cause black screens, instability, and crashes
Mapping more than one display or Zone to a Blackmagic DeckLink Capture Source will cause playback problems and black screens
Mapping multiple displays or Zones to a source with a Mirror Group changes this behavior.
Interactive Sources will all display the same single instance of the application
Direct Sources will play a single synchronized set of content overall displays and Zones
Blackmagic DeckLink Capture Sources will display in synchronization across all displays and Zones
Mirror Groups also allow you to play the same content across multiple individual displays and Zones of varying sizes and aspect ratios at the same time.
In this example, we’ve captured content being mirrored across three Zones. Zone-2 and Zone-3 are single 16:9 displays, and Zone-1 is a tall aspect ratio where content is being stretched to fit. All three zones are still playing the content in perfect synchronization.
Using Interactive Sources without a Mirror Group means that managing the application session on every screen must be done individually, with Interactive Viewer sessions started and used on every display or Zone.
When a Mirror Group is used, only one instance of the Source application is started, and every display receives that instance. Instead of accessing Interactive Viewer through the individual Display or Zone, it is run from the Mirror Group’s control panel.
Start by mapping two or more displays or Zones to the source you want to use. You may receive a warning to create a Mirror Group to improve performance. This warning appears any time you assign more than one display or Zone to a Direct Source, but not an Interactive one.
Select On to enable a Mirror Group
Edit the default name of the Mirror Group if required
Select a Control Display from the drop-down. This should be the display or Zone that is least likely to be removed from the Mirror Group, stopped, or turned off. Virtual Displays cannot be Control Displays
Set the Frame Rate for the group.
Select the Sound Output from the drop-down menu. Audio will only route through the Control Display.
Click OK to complete the process, and Apply to start the Mirror Group
Cloud servers have only the first two functions described above.
Default Mapping: Newly paired displays or created zones will be assigned to this Resource Group.
Show Welcome Screen: Instead of running the first source in the list, the display or zone will show a Welcome Screen where a user must select a source to start. Used mostly for Public Computing and interactive kiosks.
You can create a welcome screen with only one source, though 4 or more are recommended. Click on the icon to enable the welcome screen . Next, click on the option to open the welcome screen configuration window.
Click on the icon on the right to open the Mirror Group Configuration window.
