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.
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.
Timecode: monitor RP-188 timecode and configure timecode window burn output
(Note: SMPTE 12M-2 is the updated name and specification for what was RP-188)
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)
