KONA Capture, Display, Convert v15.2 28 www.aja.com
Secondary Format
NOTE: A secondary format is not available on a KONA 4 operating in 4K Mode, or on the
KONA 5 or KONA 1 cards.
Any format other than the currently selected Primary Format is a secondary
format. As described previously, this means that either the Inputs or Outputs are
somehow different from the framebuffer’s assigned format—the Primary Format.
A conversion is readily apparent because of the color change from blue.
In some cases the application you use with the KONA will automatically set the
Primary Format, overriding the user’s selected primary format in the AJA Control
Panel.
Conversion Icons
When an input or output is a different standard than the framebuffer, the KONA
may be up- down- or cross-converting the signal to the selected standard. This
may be automatic, because it has detected an input signal that differs from
the standard currently selected, or because you’ve explicitly told it to convert.
In either case, the block diagram will show the conversion by displaying a
conversion icon in between the input/output and the framebuffer.

Controlling Application
It is important to understand that your computer may contain many applications
that can use the AJA device (as you switch from window to window) and it may
not always be obvious which currently controls it. In the top right corner, the
Control Panel displays the name of the application controlling the unit.
Figure 24. Control Panel In Use Message (in red)
KONA is very flexible and most controlling applications perform the necessary
housekeeping so they work correctly when they’re active and when they’re not.
This means that the application that is “active” (in front) will be granted control
of the KONA video output. Generally, when you switch to a different application,
the previous application lets go of the video output and the new application gets
control.
In some cases, however, applications may not always properly “let go” of the I/O
interface as another takes over. If this occurs you’ll be able to tell by looking at the
Control Panel's in use application name.
