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 Icon
Conversion Icons—
when an input or output is a different standard than the framebuffer,
the Io XT may be up- down- or cross-converting the signal to the selected 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.
Color Meanings—
All items in the Io XT 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: the selected operation cannot be performed
Yellow: reference video (black burst or other reference source)
Green: indicates that Io XT is performing an active change to the video making it
different from the Primary Format (e.g., down-conversion).
Control Panel Screens
—The side area of the Io XT Control Panel provides different
information categorized by topics. Clicking on a topic—or a block diagram element—
displays an information screen corresponding to that topic. Screens that can be selected
are:
Control:
configures Io XT operation and output timing.
Format
:
select the framebuffer primary video format and any secondary formats for
conversion of inputs/outputs
Input Select:
view and edit input selections and how they are mapped
SDI Out:
select output format
HDMI:
configure the HDMI I/O
Analog Out:
configure the component/composite analog output
Video Setup:
configures Video such as composite black level.
Audio Setup:
configures Audio options such as analog audio monitor level.
DS Keyer:
setup and control the insertion of keyed video from the frame buffer or
graphics files with alpha channel.
Presets:
add or delete saved preset configurations (handy for setting up the Io XT for
certain workflows and then saving it as a canned configuration for easy later recall)
Firmware:
enables installation of AJA card firmware.
Info:
displays status information and firmware version # of the Io XT and how it
is installed in the host Macintosh. This information is generally intended for
troubleshooting/support.
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. The lines will also
