The interface between systems and signs has historically required encoded character strings, which whilst functional can lead to complexity in creation and debugging.
Swarco Mizar has developed a standard protocol based on
-
Human readable format
- Open;
- Easy to validate using
- Easily extensible
- Self-describing
- Extensive tool support
DisplayML is an open protocol and anybody is free to use it.
Information transferred via DisplayML:
- Configuration messages:
- Templates outlining the layout of the display
- Font files
- Image files
- Software for remote control of the sign
- Display data
- Data to display (text, pictures, sound etc.)
- Where and when?
- Communication
- Communication related messages
DisplayML tools
Swarco Mizar has also developed a number of tools, applications and components for supporting the use of DisplayML. These are developed using the latest .NET technology and runs on any standard PC platform which means that it is easy to install and to use:
-
DisplayML Layout Designer (DLD), a WYSIWYG[1] application for building and modifying layouts in an extremely flexible way for any DisplayML-compatible device.
-
DisplayML File Distributor (DFD), a tool for sending files to any DisplayML-compatible device. These files can be software upgrades, images, fonts etc.
-
