Format Tab Screen
The Formats screen shows the video format currently in use by the Io XT framebuffer (called
the
Primary Format
) and allows you to change it. All throughout the Control Panel, choices are
always presented based on what Io XT can do with the signals available and the inputs/
outputs selected. For example, on the Format screen, if the output or inputs are a different
format than the primary, then you’ll see an additional information pane that allows you to
view and edit the secondary format—including control over whether up/down/cross
conversion is employed.

Video Format (Primary and Secondary)
—these pull-down menus show the currently
selected formats. If you select an alternate value in the Primary Format using the pull-
down, it will change the format used by Io XT's framebuffer. When a change is made via
the Video Format pull-down or by clicking an icon (widget) and selecting a new format
via a contextual menu, the block diagram will change to reflect the new format. In the
case of a Secondary Format, the formats available can vary based on what the Primary
Format is and the input signal (frame rates of input sources limits the to/from conversion
choices). The “Secondary Video Format” pull-down menu lists all compatible formats for
selection (incompatible formats are not shown). This allows you to see what you've
chosen, and also see those formats that are compatible with the selected Primary format.
The
RGB Range
pulldown menu allows you to select either Full range (0-1023) or SMPTE
range (typically 64-940) for RGB color output.
