KONA LHe Plus Installation & Operation Guide — Using The AJA Control Panel

AJA Control Panel, Block Diagram

Framebuffer—the framebuffer is the “engine” in the KONA LHe Plus where active video

operations take place using 3rd-party applications, or even the KONA itself. The

framebuffer has a format (called the “Primary Format” and color space that it follows,

as defined in the Control Panel or via external third-party application software).

It is important to realize that inside the computer, many applications can use the

KONA LHe Plus (as you switch from window to window) and it may not always be

obvious which is currently controlling it. The AJA Control Panel displays the name of

the application controlling the card in red text at the top right of the Control Panel

Screen. See “Who is Controlling KONA?” on page 53. If an application does not

properly “let go” of the KONA as another takes over-you'll be able to tell by looking at

the Control Panel.

Primary (Framebuffer) Format—the video format currently assigned to KONA LHe Plus.

This is the format that the framebuffer will use and is shown in the Control Panel

using the color blue. All icons in blue are the same as the Primary Format used by the

framebuffer. Also any text descriptions in the block diagram that appear in blue also

indicate that something is in the primary format. So, for example, if you see that the

input and output icons are blue, then you know that the same format is used

throughout the video path and that no format conversion is being performed. If a

different color is displayed on the input or output, green for example, then you know

that the KONA LHe Plus is performing a format conversion in the video path.

Secondary Format—any form

at 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 (i.e., the

“Primary Format”). This can be seen at a glance because the color will be different

than blue.
