Features and Capabilities of the Visionary System
In addition to receipt and redistribution of EAS messaging from the EASyCAST encoder/decoder,
the Visionary gives station operators the ability to create custom messages. Through the
Visionary Editor software, custom messages and graphics can be inserted into the broadcast
display.
Custom EAS Messages
The Editor software allows the creation of custom messaging in the form of static text, crawl
text, and custom logo insertion. Static text can be placed anywhere on the screen, and all
movement parameters for text crawls can be controlled. Customizable text properties include
position, font, size, color, background color, transparency, crawl speed, and the number of
times the crawl is repeated.
Logo Display
Multiple logos/images can be placed on the screen, with independent control over location,
transparency, and fade in/out for each graphic.
How the Visionary System Functions in an EAS Activation
During normal broadcasting, video is routed through the Visionary SDI input and output. Audio is
routed through the Visionary embedded in the SDI, or through the baseband audio or AES/EBU
inputs and outputs.
During EAS activations, the EASyCAST encoder/decoder sends EAS crawl and custom image
information to the Visionary over the Ethernet interface. EAS audio is supplied to the Visionary
baseband audio inputs, or sent over Ethernet as an audio file (.wav).
Using contact closure inputs, automation and commercial insertion equipment can be used to hold
off EAS messages during commercials or other important programming. The Visionary will hold
all messages in queue until automation equipment or an operator provides a trigger to release
queued messages. Operators can also trigger the Visionary using Ethernet commands from a
PC-based software application.
