projectors control or remote control. 
Primary Colors Colors usually three, which are combined to produce the full range of  
other colors within the limits of a system. All non-primary colors are mixtures of two or 
more of the primary colors. In television, the primary colors are specific sets of red, green, 
and blue.   
Progressive scan Computer images are all progressively scanned. Now, we are using 
this type of scanning for HDTV. Instead of having two fields and interlacing them together 
to form a frame or an image, we show each frame of a video image completely, from top 
to bottom, not interlaced. 
Q 
R 
RCA jacks RCA connections for RCA cables, carrying line-level audio signals and some-
times video signals. 
Resolution (A) A measure of the ability of a camera or television system to reproduce de-
tail. That is the number of picture elements that can be reproduced with good definition. It 
is a factor of the pickup device or the TV CRT characteristics and the signal bandwidth. 
(B) Generally called horizontal 
resolution. It can be evaluated by establishing the limit to which lines can be distinguished 
on a test pattern. A larger resolution value means a broader frequency band of the video 
signal. (C) A measure of the greatest amount of detail that can be seen, or resolved, in an 
image. Often incorrectly expresses as a number of pixels on a given line. More correct is 
the bandwidth. 
RGB, RGB Format, RGB System Red, Green, and Blue: The basic parallel component 
set in which a signal is used for each primary color; or the related equipment or intercon-
nect formats or standards. The same signals may also be call GBR as a reminder of the 
mechanical sequence of connections in the SMPTE interconnect standard. 
S 
SW -  Switch 
S-VIDEO - The generic name for Y/C video, applied to S-VHS or Beta ED 
Sampling A process in which an analog signal is converted into a series of digital values. 
Saturation The quantity of chrominance information present, (for example, the difference 
between red and pink is that red is more saturated than pink.) 
Set Up - A reference to the black level in the videotape signal, also known as pedestal. 
Signal A variation in an electrical current that represents either an audio signal or a video 
signal. 
Signal-to-Noise Ratio (S/N) - An S/N ratio can be given for the luminance signal, chromi-
nance signal; and audio signal. The S/N ratio is the ratio of noise to actual total signal, and 
it shows how much higher the signal level is than the level of noise. It is expressed in deci-
bels (dB), and the bigger the value is, the more crisp and clear the picture and sound will 
be during playback.  
Sub carrier Also SC, 3.58, 3.58CW - This is the basic signal in all NTSC sync signals. It is 
a continuous sine wave, usually generated and distributed at 2 volts in amplitude, and has 
a frequency of 3.579545MHz. Sub carrier is usually divided down from a primary crystal 
running at 4.318180MHz, and that divided by 4 is 3.579545. All other synchronizing sig-
nals are directly divided down from 
sub carrier. 
Sync Also Composite Sync - This signal is derived from a composite or combination of 
horizontal and vertical drives, with some slightly narrowed and delayed pulses as well as 
the addition of equalizing pulses. It is one of the more popular signals used in video

systems today, and when used, is usually accompanied by sub carrier. 
T 
Tape A medium capable of storing an electronic signal and consisting of backing, binder, 
and iron oxide coating. The orientation of the iron oxide determines whether the tape can 
be used for helical scan video recording. 
Tape Guides Guides that are replaced on a VTR that make sure the tape stays within the 
correct path from the supply reel to the take up reel. 
Test Signals Signals such as color bars, stair step, multiburst and cross hatch that are 
used in the setting up and checking out of a VTR. 
Time Code - A labeling system that is used to identify a specific frame of videotape. It can 
be an audio signal recorded on Track 2 or a video signal that is recorded in the vertical 
interval of a tape. 
Time Code Editing By recording a sequential time code along with the video and audio 
material, you can obtain a more precise reference for editing. Each frame has its own 
number or code, which tells the time in hours, minutes, and seconds, and includes a frame 
number. The world standard code is called SMPTE (Society of Motion Picture and Televi-
sion Engineers) and has also been adopted by the IEC (International Elecrotechnical Com-
mission). Time codes permit very fast and accurate editing. Automatic editing is possible 
under computer control. 
Tripod A three-legged stand on top of which a camera is mounted  
Tripod Head The top portion of a tripod where its legs meet and the camera is mounted; 
friction or fluid-head tripod designs are available. 
U 
UL - Underwriters Laboratory. 
Underwriters Laboratory (UL) A non-profit safety organization in the U.S. that inspects 
and certifies the products sold in the U.S. for their safety standards. 
V 
VCR - Video Cassette Recorder. 
VITC - Vertical Interval Time code 
VTR Video tape recorder 
Vertical Interval That portion of the video signal that includes the vertical blanking, the 
vertical sync pulses and the pre and post-equalizing pulses. It is also the area where other 
information that is carried with the television signal, such as captioning and satellite in-
structions, are inserted. 
Vertical Scan The action of the electron beam sweeping across the entire face of the dis-
play. 
Video Level A measurement of the video level or luminance level of the video signal. The 
video level should not exceed 100 IRE units. 
W 
Watt Is a unit of measurement of power. 
WFM (WAVEFORM MONITOR) - A type of oscilloscope that is used to display the lumi-
nance, chrominance and timing diagrams of the video signal. 
White Balance A method of setting a camera for the correct color temperature. 
X 
Y 
Y Signal The luminance portion of the color signal. 
Z 
Zoom Lens A lens with a variable focal length. Which allows you to adjust the size of the 
image on a screen by adjusting the zoom lens.
