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

Figure 4 Typical GPI Connections
Typical GPI connections for the ticker job require only one set of wires. Ad insertion equipment
should have some sort of contact closure, GPI output, or relay that will make a low (0V) or
simple ground. The Protector reacts to the GPI based on how you program it in the Event
Controller covered later in this manual.
Most contact closure outputs from the ad inserters will be labeled + and -; in reality, the Protector
won’t care, but following these symbols will ensure proper connection.
Use the removable 10-pin plug (green Phoenix type). Strip your GPI contacts from the ad
inserter; insert stripped end into plug; tighten locking screws; plug 10-pin plug back into bottom
row of the GPI plug (labeled GPI).

INITIAL SETUP
Out of the box, the Protector is programmed to run video compression sequences triggered by
GPI pulses. You can make the video connections and the GPI connections, and have response
from the Protector, but it’s much more than that. The Protector software contains an Event
Controller that will allow you to set functions based on dates and times. Your Protector can then
“squeeze” video when you need it, and maintain full screen video when you don’t.
For initial installation, you will need to connect an SVGA (800 x 600 progressive scan) monitor,
a mouse (PS2 or USB) and a keyboard. Also, to utilize the full function of the unit, you should
take the time to connect it to your Local Area Network (LAN). With the Ethernet or LAN
connection, you have the capability to control the unit from any Internet connected PC
worldwide (so, while you’re off at NAB, and the ticker is running overtime, you can log on and
change the Protector’s settings to keep your viewers tuned in to your revenue generating ads).
Once initial setup is complete, you can remove the monitor, mouse, and keyboard…but leave the
LAN connected.
After you have connected the computer peripherals, power up the Protector as described in the
following paragraphs.
Please don’t hesitate to call or email us with any questions you may have, or just for general
assistance.

OPERATION
The Protector is a microprocessor-based system. The current operating system is running on a
500 MHz or greater CPU. The operating system is 2000 Professional. See appendix __ for
typical LAN software settings.
The main software engine of the Protector is the Graphical User Interface (GUI). The GUI is a
custom application that gives you full control over all features of the video scaling board and the
combining board. The combiner handles all of the general-purpose interrupt (GPI) function as
well as the mixing of foreground and background video. The unit also features two distributed
background outputs for use in other areas of your system (one of which is used as a genlock
signal for the foreground video). With the built in flexibility of the system and its GUI, the
system can serve many purposes, however, this manual will cover the most important facets of
the “stock ticker” application. So, let’s get started!
GETTING STARTED
Once you have every thing connected for initial setup we can configure the Protector for
operation.
Set the MAIN POWER SWITCH (fig. 1) to the ON position (noted by a visible white dash at the
top of the main power switch).
Once the operating system is up and running, you will get a network sign-on prompt. The initial
start up USER ID and PASSWORD are both the serial number of your Protector. The user may
change this once in and comfortable with the operation of the unit.

Once you successfully log on to a network, or CANCEL network log on if you choose to run the
system off-line, the Protector GUI will auto-run. The next thing you should see on your setup
monitor is the GUI’s request for you to choose a COMM PORT. For virtually all setups, select
COMM 1 (this is the default if you simply press enter at this point) and click OK. Note, if the
Protector has been configured to “auto-start” this page may not be seen.
The GUI will now verify the port you selected, and if all is correct will immediately take you to
the initialize routine.
INITIALIZE SYSTEM
You will now encounter three successive initialize screens that ask you to verify that you’re
ready to start the system and initialize the video processing boards. Click OK if you’re ready on
all three initialize screens.
Select Port 1
Click OK

The GUI should now be loaded, and you’ll see one of the main screens on your setup monitor.
(Fig. 5).
The Protector is calibrated for video levels and timings at the factory, but you may wish to tweak
these values to perfectly match your system. These adjustments are made on the MAIN form.
(Fig. 5)
MAIN SCREEN
Use this form to adjust your proc amp settings (color, bright, contrast, hue, and timings). This
form also contains controls for the remaining features of the Protector video processing board
set. The Protector is set to broadcast standards at the factory. You can fade video to black, mix
video between foreground and background, as well as other functions. These functions are not
used in the stock ticker job, and we STRONGLY recommend you don’t change any of the
settings that you don’t need! But, just in case, should buttons be “clicked” to just take it for a
spin…you can always recover to original settings by clicking RECALL POR or as a last resort,

re-booting the system. Use caution when “test driving” the system, for if you do press the
STORE POR button, whatever settings you’ve changed will be the new default state.
If you have made changes that you wish to save, simply click STORE PROC (to store the proc
amp settings) and then click STORE POR (to store the default state).
Using the menu bar at the top of this, and all other major screens within the software, you can
immediately access any of the other forms.
The next form of some interest would be the KEYFRAME FORM. Click KEYFRAME on the
menu bar.

First, a little definition of a Keyframe: A Keyframe is a conglomeration of several settings
within the VP boards. It consists of size, position, transition frame count, transition mode,
border and crop settings. You can store 10 different keyframes within the Protector, and you can
transition between them. The style of transition can either be a cut or a mix, or be of several
different modes.
Each keyframe must be stored as either a start, stop, continue, loop, or pause keyframe. Forward
transitions always begin with a start keyframe. For a more detailed discussion of the Keyframes
and transition sequencing, see appendix ___ covering processor board function.
In general, for the stock ticker job, you will use only Keyframe 0 and Keyframe 1. Keyframe 0
is preset at the factory to be a full screen, no borders, and no crop, start keyframe, that is set to
transition within 1 frame (or transition in 1/30th of a second). Keyframe 1 is factory preset as a
picture-in-picture effect, designed to display compressed foreground video, and reveal the
bottom 1/3 of the background video (the stock ticker). Keyframe 1 is a stop keyframe set at the
same position as Keyframe 0, but the vertical size is adjusted down to 195 lines (as opposed to
242 lines for a full screen display). Keyframe 1 is also set to transition within 1 frame.
The Keyframe screen gives you the ability to change a variety of settings.
The six buttons across the top allow you to manually run transitions between keyframes. You
can use this function to force a transition. Use the Forward and Reverse buttons to transition
between keyframe 0 and 1 (fig. 7).

The larger black directional arrows give you the ability to change size and position of the
foreground video (IN FROM INSERTER). You can also manually type in desired sizes and
positions at the bottom of that frame, and click ENTER to immediately change the size and
position of the foreground video (fig 8).
Border and crop are not used in the stock ticker job, but if you wish to test drive, you’ll need to
“squeeze” the foreground video down some, and move it so that all 4 edges are visible. You can
then “play” with the border and crop settings to add full color borders to your foreground, and/or
crop the foreground to mask unwanted parts of the foreground (such as blanking interval
differences usually visible on the left edge of a “squeezed” foreground).
Alpha Key Mode and Background Modes are further explained in Appendix ____. Again, they
are not used in the stock ticker installation, but changing these settings could change the display
to an undesirable state. Remember, to recover, press RECALL POR or re-boot the system.

TRANSISTION SCREEN
The TRANSITION screen is accessed by clicking TRANSITION on a main screen’s menu bar.
This screen is a small sized screen, with a blue background, that will allow you to manually
create a transition from the current keyframe, or video state, to a new state, over a time that you
manually type in the FRAME COUNT block (fig. 9).
A quick way to recover from a size and position setting that are not what you want, is to return to
the KEYFRAME SCREEN and press the JUMP BACK ( Bh ) button at the top left of the screen
(fig. 7).

GPIO
The GPIO screen (fig. 10) can be accessed through the Main screen menu bar. Click on GPIO.
This screen allows for manual setting of the GPI and GPO functions. Each GPI and GPO has
multiple states of operation. For the ticker job however, only two are of significant
consideration.
As shown in figure 4, the GPI consists of a two-wire contact closure link from the video inserter
device. In the GUI, you want only GPI 1 to be used, and you have two states in which the GPI
should be set. GPI #1 Sequence Follow, and GPI # 1 Off. As you will see in the Event
Controller section of this manual, GPI #1 Sequence Follow will force the Protector to react to is
contact closures from the ad inserter. The Protector will “squeeze” the foreground (local ad
insert) while the GPI is low (or the contact closure is closed) and will return to full screen when
the GPI is high (or the contact closure is open).
Setting the GPI to OFF, will force the Protector to ignore GPI inputs. This mode is used when
you don’t want the Protector to compress the local ad (at times when the stock ticker is not on
the network feed—nights, weekends, holidays).

Using the GPIO screen can be useful if the Protector has entered an incorrect mode (such as,
being in SEQUENCE FOLLOW mode when it should have been GPI OFF mode…you can use
this screen to manually force the unit into the correct mode).
A second possible time you may want to use the GPIO screen is during special coverage from
the network. It has occurred during erratic market swings, that the network ran the ticker after
normal hours and through weekends. For this occurrence, it would be beneficial to force the
Protector into the SEQUENCE FOLLOW mode for GPI #1, rather than changing you normal
programming in the EVENT CONTROLLER. So, when normal schedules resume, the Protector
will still be programmed correctly.
With this basic knowledge, we’re ready to examine the most important part of the GUI for the
stock ticker job—the EVENT CONTROLLER.

EVENT CONTROLLER
To access the EVENT CONTROLLER, click on EVENTS on a main screen. A blue background
event controller programming screen will appear (fig. 11).
Figure 11

The event controller is capable of an infinite number of programmings, but for the ticker job, the
10 that initially appear on the screen are more than enough. In fact, only two are absolutely
necessary.
To program an event, you must first know exactly what you want the unit to do. For the stock
ticker job, you more than likely want the local ads to be compressed during times that the ticker
is present on the national feed, and you want the local ads full screen when no national ticker is
present.
This makes programming very simple. You will program EVENT #1 to send the Protector GPI
#1 into SEQUENCE FOLLOW mode during ticker times. You will then program EVENT #2 to
send the Protector GPI #1 to OFF mode during non-ticker times.
So, let’s take a look at what you have to do to make this happen!
Across the top of the Event Controller form, you will see five white text boxes (fig. 12).
The first box is for selecting a specific date. You may want to select a specific date to program a
certain day differently than most days, such as a holiday. For our purposes though, you will
want to make a couple of events that run the same every weekday, so DESELECT EVENT
DATE box by clicking on the checkmark, and ensuring the checkmark disappears (fig. 13).

10 July 2000
Move to the next white box, the EVENT TIME box. Since you are setting the on event first,
you’ll want to select the time in this box at which you want the Protector to begin compressing
the local ad (this should be the time when the national ticker begins in your area). We’ll use 5:00
AM for this example, but you can set it to any desired time for your locale. Change the time in
this EVENT TIME box by placing the cursor over the hours, minutes, seconds, or AM/PM
consecutively. Use the up and down arrows that are part of this box to change the event time to
your desired time. Ensure your AM/PM is set correctly (fig. 14)!
Once you have the proper “on” time set, move to the EVENT MONTH box. For normal ticker
operations, you’ll want to set this at EVERY MONTH by pressing the down arrow on this box,
and clicking on EVERY MONTH. You want this setting of course, because the ticker happens
every month (fig. 15).

10 July 2000
Next, move to the EVENT DAY OF THE WEEK box. Here, you’ll want to use the down arrow,
and select WEEKDAYS ONLY. This selection is made because in the vast majority of
instances, you will only want the local ads compressed during normal business days, and full
screen on the weekends (fig. 16).
Now, move to the SELECT EVENT (1 – 10 ) box. Since we are setting up the “on” condition,
you will want to select GPI 1 SEQUENCE FOLLOW. Ignore the other options; they aren’t
necessary for this ticker protector job!
Review the white boxes at the top of the Event Controller--you have preset the Protector for the
on conditions—from left to right, you should see that the EVENT DATE box is de-selected (no
checkmark); the EVENT TIME box should contain the time at which you want local ad
compression to begin; the EVENT MONTH box should read EVERY MONTH; the EVENT
DAY OF THE WEEK box should display WEEKDAYS ONLY; and the SELECT EVENT box
should read GPI 1 SEQ FOLLOW (sequence follow) (fig. 17).
