Instruction manual

Input/Output Icons—the input and output icons are triangles that together with

their color show all the input and outputs and their status (selected, not

selected, input present or not, format, etc.). A complete video path is shown

when inputs and outputs are connected with lines going to/from the

framebuffer.

Input/Output Icons

Conversion Icons—when an input or output is a different standard than the

framebuffer then the Io HD may be upconverting, downconverting or

crossconverting the signal to the proper standard. This may be automatic,

because it's 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. In the case of cross-

conversion, the type of crossconvert will be shown under the icon (in the

example that follows, it's “1080 to 720”).

Down, Up, and Cross Conversion

Icons

Color Meanings—all items in the AJA Control Panel block diagram are color-

coded to show what is happening in realtime. This applies to both icons and

text. These colors have the following corresponding meanings:

Blue: video is same format as the Primary Format (framebuffer)

Red: there is no video, the selected operation cannot be performed, or an

invalid selection has been made

Yellow: reference video (black burst or other reference source)

Green: indicates that Io HD is performing some kind of active change to the

video, to make it different from the Primary Format (e.g., up/down/cross

convert, SD-SD aspect change, etc.).
