Instruction manual

You can even access the AJA Control Panel application without exiting the

application by ﬁrst holding down the command key (Apple key) before mouse

clicking on the AJA Control Panel application on the desktop.

For this reason, it is useful to leave the AJA Control Panel application on the

desktop while you work in applications and simply command click into it to

access it if you are unsure of a setting or wish to make a change.

Control Panel

Basics

Although the Io HD auto-detects the input format depending on the input

presented, and the Control Panel intuitively shows at a glance much about what

the Io HD is doing—there is even more information presented that may not be

obvious. To ensure you make the most of the software, run the AJA Control Panel

application and look at its display. Then refer to the “Basics” described here to

better understand what you're seeing and learn how to view and change the Io

HD system conﬁguration.

Before we go into too much detail, here are some basic deﬁnitions you should

know (please refer to the ﬁgure that follows for reference). After studying the

basics, read “Who is Controlling Io HD?” later in this chapter for more advanced

information on how applications interact with the Io HD.

Block Diagram Screen—the top area of the AJA Control Panel shows a visual

picture representing the processing (if any) that's currently occurring,

including inputs/outputs, any up/down/cross conversion, reference source,

and system status. Lines between inputs, the framebuffer, and outputs, show a

video path. Where there are no lines, it shows there is no connection; this can

be either because an input or output isn't selected or because no video is

present at the selected input.

Icon objects on the block diagram screen (input/output icons, frame buffer,

etc.-also called “widgets”-indicate their status by color (explained later) and

can be clicked for context-sensitive information and choices. (These same

choices can also be made from the tabbed Control panel screens.)
