Section 1: Introduction
RGB VIDEO
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. Refer
to TTL Video.
RS-232
A common asynchronous data transmission standard recommended by the Electronics Industries Association (EIA).
Also called serial communication.
RS-422
A less common asynchronous data transmission standard in which balanced differential voltage is specified. RS-422 is
especially suited to long distances.
S-VIDEO
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. Also known as Y/C.
SCAN FREQUENCY
The horizontal or vertical frequency at which images are generated. Also known as scan rate or refresh rate.
SCAN LINE
One horizontal line on the display.
SECAM
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.
SHOW SCRIPT
A small file consisting of automation cues in addition to a play list, triggering theatre events (action data), and possibly
including parameters that allow the program to be tailored for a specific venue or engagement. A show script is created
by the exhibitor or installer and provides automated presentations. Automation not yet available.
SNMP
The Internet standard protocol developed to manage nodes (servers, workstations, routers, switches and hubs etc.) on
an IP network. SNMP enables network administrators to manage network performance, find and solve network
problems, and plan for network growth.
SOURCE
The device (such as a server) connected to the projector for supplying incoming data.
SOURCE SETUP
Refer to Channel.
