'
The maximum number of alternate white and black horizontal lines that can be
distinguished on a screen when a photographic target is placed between the lens and a
light source and illuminated by that source.
'
The maximum number of pixels that the projector can display horizontally and
vertically across an image, such as 1024 x 768 (called XGA).
'
The minimum time required for a CRT projector to move the position of the scanning
spot from the right edge to the left edge.
'
The time required by the video amplifier of the projector to increase its output from
10% to 90% of the maximum value.
'
The video output (analog or digital) of most computers. Analog RGB video can have
3, 4, or 5 wires — one each for red, green, and blue, and either none, one or two for
sync. For three-wire RGB, the green wire usually provides sync. (See TTL Video).
'
A common asynchronous data transmission standard recommended by the
Electronics Industries Association (EIA). Also called serial communication.
'
A less common asynchronous data transmission standard in which balanced
differential voltage is specified. RS-422 is especially suited to long distances.
'
The output from certain video tape players and video equipment. S-Video separates
sync and luminance from color information, typically producing a higher quality
display than composite video.
'
The horizontal or vertical frequency at which images are generated.
'
One horizontal line on the display.
'
A video output format of some video tape and disk players (used primarily in
France). SECAM (Sequential Couleur á Mémoire) signals are similar in resolution
and frequency to PAL signals. The primary difference between the two standards is
in the way color information is encoded.
'
A slidebar is a graphical display of an adjustable setting. The numerical setting often
represents a percentage but can be a specific unit such as degrees Kelvin.
'
The device, such as a computer or VCR, connected to the projector for display. A
source may have numerous corresponding channels defined and recognized by the
projector. See Input.
'
See Channel.
'
A signal selector that can be connected to a projector for the purpose of adding more
sources.
'
This term refers to the part of the video signal that is used to stabilize the picture.
Sync can occur in three forms:
"Composite sync": the horizontal and vertical components are together on one
1)
cable.
2) "Sync-on-green": the sync is part of the green video.
