Keying and YUV Color Space
The unit keys using a YUV color space, which is different from RGB color values, but allows more
control of the color selection.
The images below, which are included on the USB flash drive shipped with your unit, show the
UV color values for undefined values of Y. There are two images because different formulas are
used to represent color space for HD video (BT.709) as against SD video (BT.601). While the
difference is slight, it’s important that you use the correct color space to ensure you see desired
results.
Note: When using a video feed from a PC, the color space will generally vary
depending on the PC output resolution.
By default the unit is pre-configured to key through black.
A simple method of understanding the Keying color selection process is to first set the appro-
priate test image shown above to show Full Screen on your PC. Then connect your PC video
output to the unit as its Primary input.

Setup >Layers >Primary >Source >[your source] (Assuming both Primary and Back-
ground layers are defined and legal, and the Primary layer is Full Screen)
Enable Keying.
Setup >Layers >Keying >On
Note that in this example we begin with all three color components (Y, U & V) set to a range of 0-
255 (all colors). That means when Keying is enabled, the primary image will effectively disap-
pear as all colors are keyed through, as illustrated below using the gray fill:
Next we need to configure the Keying color:
Setup >Layers >Keying
For each Y, U, and V value there are 4 settings, listed consecutively on the Y, U,or V line of the
display:

lthe range minimum
lthe range maximum
lthe softness
lan invert control (which, when "On", keys through all colors outside your range rather than
inside it).
You can decrease the range of the U value to select the color you want to key through. In the
example below, the U range is reduced to between 50 and 83 and you will see the test image
reappear as the Keying range is reduced:
tvONEC2-2x55

Note: If you have chosen the incorrect color space image to use, you may observe
that when you reduce the color range the lines are curved, rather than straight as
illustrated in these images. That usually means you have selected the wrong image
as your template. If this happens, open the image with the other color space
template.
Now the Uvalue has been specified, you can decrease the range of your V values to further
define the color that you want to key through. In the example below, the V range is reduced to
between 48 and 87:

At this point, the U and V value selections are complete. When you replace this test image with
the real video, you will see the colors encompassed by the black box keyed through to reveal
the Background layer or Back Color, as configured.
Keep in mind that the color images used so far are created with calculated Luminance (Y)
values. At the moment, we are Keying through all brightness levels of our selected color.
The next step is to replace the test image with to the real video feed you want to use, and adjust
the Y, U and V values to further define the appropriate color.
Tip: If you find that you get jagged edges between your Keying color and the video
you want to remain visible, increase the Softness setting to blur the edges until it
meets your requirements.

Common Configurations
The C2-2x55 units are capable of operating in a variety of different configurations. This section
provides a quick setup guide to show you how to set up some common configurations. This is
not an exhaustive list, but should provide instructions to set up several of the most common
usages.

When you configure the Primary layer to be shown Full Screen with the Keying color set to blue,
at a Framelocked resolution, the output will look like this:
Using the OK button and arrow keys, select the options listed below to create the desired
configuration.

1. Choose the source for your Primary layer
Setup >Layers >Primary >Source >[your source]
2. Set the Primary layer to show Full Screen
Setup >Layers >Primary >View >Full Screen
3. Turn Keying on
Setup >Layers >Keying >On
4. Configure your Keying color
See "Keying and YUV Color Space" on page11
5. Set the Background Color
Setup >Layers >Back Color; press the ok button to access RGBvalues. Use the up
and down arrows to change the values; use the left and right arrows to move to the next
or previous field. The values are standard RGBsettings with a range of 0 to 255.
1. Configure the resolution with Framelock and hide the background
There are three ways you can configure the resolution. These instructions set the resol-
ution using Framelock - the Background input determines frame rate of the output.

Note: To use manually-set Resolution or use Genlock, see the appropriate
section.
1. Select the Background source that will define the frame rate:
Setup >Layers >Background >Source > [select your background source]
2. Select Framelock and hide the Background:
Setup >Layers >Background >View >Hidden (press right arrow) Fram-
elock
3. Set your Resolution to match the Background source's frame rate:
Setup >Outputs >Video >Resolution >[select same frame rate]
Note that both Background source and output video Resolution must be the
exact same frame rate and both must be one of the following:
NTSC(59.94) 720p50 1080i50 1080p50
PAL(50) 720p59.94 1080i59.94 1080p59.94

toCV/YCsignal type. The CV/YCsignal type is only available if the output resolution
is NTSCor PAL.
