DMEs
Overview
DME (Digital Multi Effects) allows you to add three-
dimensional effects such as image movement, rotation,
magnification and shrinking, as well as a wide variety of
special effects.
You can use up to four channels as dedicated DME
channels.
Each channel can be used on its own or in combination
with other channels, which allows you to create advanced
effects with more complexity.
Note
For 4K format, the DME function cannot be used.
About DME Boards
XKS-8470 HD DME board
You can use a maximum of four channels (with two boards
installed in the switcher) of DME functionality.
Notes
• The signal that is input on DME Ext In (AUX bus
output) is set using the Setup menu (see page 416).
• The NMI input signal cannot be used on Ext In.
Transforms in Three-Dimensional
Space (Transforms)
A transform is the process of a DME placing a video image
in a three-dimensional space and subjecting it to
manipulation, such as movement, rotation, magnification,
or shrinking.
Three-dimensional space
Source space and target space
Images are placed in one of two types of space: source
space and target space.
Chapter
• Source space is a three-dimensional space using the
image itself for reference. The X- and Y-axes are defined
along the plane of the image, and the Z-axis is defined
perpendicular to the plane of the image. When you move
the image, the coordinate axes also move.
• Target space is a three-dimensional space using the
output monitor screen for reference. The X- and Y-axes
are defined as the horizontal and vertical to the plane of
the monitor screen, and the Z-axis is defined
perpendicular to the plane of the monitor screen. The
coordinates do not change even if the image moves.
Source space
For example, as shown in the following figure, the image
moves in a different direction when you move it along the
X-axis of source space and along the X-axis of target
space.
Source space
Local space and global space
The coordinates of an individual DME channel are called
its local space. The coordinates common to all channels are
called the global space.
By switching from local to global space, you can add new
movement to the movement of images in individual
channels, and also apply transform effects to multiple
channels that have been combined using global effects (see
page 255).
