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 Identifi cation Data)
Information stored in the projector that can be read by the source.
EDID is used on the HDMI, DVI and VGA inputs, allowing the source to automatically confi gure to the optimum display settings.
EDTV (Enhanced Defi nition Television)
A progressive digital television system with a lower resolution than HDTV.
Field
In
interlaced video, a part of the image frame that is scanned separately. A fi eld is a collection of either all the odd lines or all the even lines
within the frame.
Frame
One of the many still images displayed in a sequence to create a moving picture. A frame is made of horizontal lines of
pixels. For example,
a 1920x1080 frame consists of 1080 lines, each containing 1920 pixels. In analog video frames are scanned one at a time (progressive
scanning) or split into fields for each fi eld to be scanned separately (interlaced video).
Frame rate
The number of
frames shown per second (fps). In TV and video, a frame rate is the rate at which the display device scans the screen to
“draw” the frame.
Frame rate multiplication
To stop low
frame rate 3D images from fl ickering, frame rate multiplication can be used, which increases the displayed frame rate by two or
three times.
