Presentation System Overview - Barco Event Master E2 Series User Manual

In addition, since the configuration parameters and presets are stored on the Event Master processor unit,
multiple instances of the GUI can be run simultaneously on different computers expanding the control
possibilities.
Refer to the chapter "EM GUI orientation", page 103 for more information about the GUI. Subsequently in this
User's Guide, the Event Master Control Software will be referred as the EM GUI.
Event Master Controller
The Event Master Controllers are dedicated hardware consoles specifically designed to support the Event
Master Series Processors, devices and systems created from several of them.
It runs from the same software as the Event Master ToolSet, but EC-200/EC-210 on an industrial operating
system with optimized hardware. All of them include tactile operation style with buttons and touch screen
displays allowing for easy and direct control.
Rudimentary Preset recall protocol for a single Processor is the same as for earlier products like Encore™ and
FSN Production Switching system.
An API based on JSON (JavaScript Object Notation) is available for developers who need to create custom
control programs and interfaces.

3.6 Presentation System overview

Advanced video processing
The Event Master processors are the most advanced video processing and presentation control systems on
the market today. These systems provide source selection, windowing, seamless switching, video effects and
integrated control for professional presentations. The modular and scalable architecture of the Event Master
processors allow support for a wide variety of show configurations.
A word about Layers
A layer is an image display element stacked on top of another or a background. Within the Event Master
processor, each mixer has two layers, A and B, and one Background layer. For complete flexibility, each
layer can be assigned to either PIP or Key functionality.
The Background layer has the lowest priority. Any input or inputs can be used as a background. This layer
visually appears behind all other PIPs and keys. The system can transition between two background sources.
PIP layer appears over backgrounds and under other layers of higher priority. PIP effects include mixes,
smooth moves, resizing, adjustable aspect ratio, borders and drop shadows.
Key layer also appears over backgrounds and under other layers of higher priority. Key effects include
luminance (luma) keys, chrominance (chroma) keys, and cut + fill (linear) keys.
