A-5
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 relatively rare asynchronous data transmission standard in which balanced
voltage is specified. RS-422 is used for exceptionally long distances only.
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
usually represents a percentage.
The device, such as a computer or VCR, connected to the projector for display.
A source is identified as
,
,
or
, or as other user-defined
numbers. Sources have corresponding channels recognized by the projector.
See Channel Number.
See Channel.
The diameter of the smallest dot that can be generated by a CRT projector.
VistaGRAPHX 2500 has a fixed spot (pixel) size.
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:
1)
"Composite sync": the horizontal and vertical components are together on
one cable.
2)
"Sync-on-green": the sync is part of the green video.
3)
"Separate sync" or "H.SYNC and V.SYNC": the horizontal and vertical
components of the sync are on two separate cables.
The duration of each sync pulse generated by a computer. The sync width is part
of the blanking time.
A type of RGB video with digital characteristics.
A wire connecting a single video source to a display device, such as a projector,
must be terminated by a resistance (usually 75
S for video).
