INTRODUCTION
The Protector is designed specifically for maintaining a background image while displaying a
compressed foreground image. The need for the Protector stemmed from CNBC
<
broadcasts of
a real-time stock ticker. When local cable affiliates insert local advertisements without the use
of the Protector or its predecessors, the CNBC
<
ticker would be covered for a period of time.
With the boom of day-trading, it became a nuisance to have your ticker covered when the local
ad was playing, since you’d have to wait until your stock listing made the rounds again—and as
the “law” goes, the local ad would come on exactly at the wrong time, covering the one stock
you’d been waiting to see…to buy…. to sell!
The Protector incorporates a state-of-the art digital video-processing device that is actually a full
frame sync/time base corrector, with video scaling capability. The Protector also features a built-
in video combiner for “picture-in-picture” effects (such as revealing a portion of a background
video source). In addition, the Protector serves the purpose of many other devices in former
installations—it replaces a separate timer device with its own graphical user interface (GUI)
event controller—it replaces a separate distribution amplifier with its own included distribution
system—it replaces a separate Vertical Blanking Interval (VBI) extractor/inserter with its own
VBI electronics (broadcast quality closed-captioning passes transparently through the device).
The Protector also provides the additional features of direct LAN interface, optional dial-up
control, and consolidated 2 rack-unit high chassis.
The Protector is well suited for the “ticker” job, and combined with its DVE features, it is a
versatile and proven device that will serve you well in any video combining installation you may
encounter.

CAUTION
The Protector is configured to auto-start as soon as power is applied and the master power switch
on the rear of the unit is switched on. This is to ensure the unit will automatically re-start should
you experience power fluctuations or loss. It is therefore critical that you connect all setup
equipment prior to initial power up. The operating system may not recognize keyboards or mice if
not connected prior to boot. Equipment damage could result from failure to follow this caution.
DO NOT CONNECT PERIPHRIALS WITH POWER APPLIED TO THE PROTECTOR
