APPENDIX E: GLOSSARY OF TERMS
DDC (Display Data Channel)
Notes
EDID
A communications link between the source and projector. DDC is used on the HDMI inputs. The link is used by the source to read the
stored in the projector.
Deinterlacing
The process of converting
interlaced
video signals into
progressive
ones.
DHCP (Dynamic Host Configuration Protocol)
A network protocol that is used to configure network devices so that they can communicate on an IP network, for example by allocating an IP
address.
DMD™ (Digital Micromirror Device™)
The optical tool that transforms the electronic signal from the input source into an optical image projected on the screen. The DMD™ of a
projector has a fixed resolution, which affects the
aspect ratio
of the projected image.
A Digital Micromirror Device™ (DMD™) consists of moving microscopic mirrors. Each mirror, which acts as a pixel, is suspended between
two posts by a thin torsion hinge. It can be tilted to produce either a bright or dark pixel.
Edge blend
A method of creating a combined image by blending the adjoining edges of two or more individual images.
Edge tear
An artifact observed in
interlaced video
where the screen appears to be split horizontally. Edge tears appear when the video feed is out of
sync with the refresh rate of the display device.
EDID (Extended Display Identification Data)
Information stored in the projector that can be read by the source.
EDID is used on the DisplayPort and HDMI inputs, allowing the source to automatically configure to the optimum display settings.
