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 KONA?” later in this chapter for more advanced information on how applications
interact with KONA 3G.
Block Diagram Screen—The top area of the Control
Panel shows a visual picture representing the
processing (if any) that’s currently occurring,
including inputs/outputs, 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 because an input or
output isn’t selected. The lines will also show
whether the outputs are video or video + key.
Icon objects on the block diagram screen (input/output icons, fram e 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.)

Framebuffer—The framebuffer is the “engine” in KONA 3G where active video operations
take place using Final Cut Pro 7, other 3rd-party applications, or even KONA 3G itself.
The framebuffer has a format (called the “Primary Format” and color space that it
follows, as defined in the Tabbed Windows or via external application software (such as
the “Easy Setups” in Final Cut). It is important to realize that inside the Macintosh many
applications can use the KONA 3G (as you switch from window to window) and it may
