DME
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. DME is the general name for all of these effects.
You can use up to eight 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.
Functions that can be used differ with the models of DME. For details, see
“Functional Differences With Models of DME” (page 1014).
MVE-8000A Multi Format DME Processor
The MVE-8000A is a “Digital Multi Effects” with multi-format support.
An optional input/output board (MKE-8021A) is available as a dedicated
interface for use of the MVE-8000A together with a switcher.
MVE-9000 Multi Format DME Processor
The MVE-9000 is a “Digital Multi Effects” with multi-format support.
An optional input/output board (MKE-9021M) is available as a dedicated
interface for use of the MVE-9000 together with an MVS-8000 series switcher.
Three-Dimensional Transformations
Transformation is the process of placing a video image in a three-dimensional
DME coordinate space and subjecting it to manipulations such as movement,
rotation, magnification or shrinking.
Three-dimensional coordinate space
Source coordinate space and target coordinate space
Images are placed in one of two types of coordinate space: source coordinate
space and target coordinate space.
• The source coordinate space is a three-dimensional coordinate space with
reference to the image itself. The x- and y-axes are defined parallel to 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.
• The target coordinate space is a three-dimensional coordinate space with
reference to the output monitor screen. The x- and y-axes are defined parallel
