Io XT Installation and Operation Guide — AJA Control Panel Overview

AJA Control Panel, Block Diagram

Framebuffer—The framebuffer is the “engine” in Io XT where active video operations

take place using Final Cut Pro 7, other 3rd-party applications, or even Io XT itself. The

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

as defined in the Tabbed Windows or via external application software (such as the

“Easy Setups” in Final Cut). It is important to realize that inside the Macintosh many

applications can use the Io XT (as you switch from window to window) and it may not

always be obvious which currently controls it.

The Control Panel displays the name of the application controlling the Io XT. In some

cases, applications may not always properly “let go” of the I/O interface as another

takes over—you’ll be able to tell by looking at the Control Panel.

Primary Format—The video format currently assigned to Io XT. 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, say green for example, then you know that Io XT is

performing a format conversion in the video path.

Secondary Format—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 (i.e., the

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

than blue.
