Io XT Installation and Operation Manual — 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, 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.
