The balanced (or differential) Audio system is made up of 3 conductors: the plus (+), minus (-) and ground. The + and - are of opposite phases so that it can drive a very long length of cable without any noise.
Range of frequencies that a signal can pass through a product without any distortion or loss of quality. The higher and wider the bandwidth, the better the resulting signal. The bandwidth is the difference between the highest and the lowest frequency of a signal, usually at -3dB of attenuation (0.7) from its maximum level.
Composite video signal, with a black picture used to synchronize (GENLOCK) certain video equipment together, therebyaligning the output. The signal is made up of vertical and horizontal sync. and Chroma burst information (1 wire).
This is the darkest level that an image can be. Usually, the adjustment of black level is set by the brightness control. The Black level is also the level of the video signal, which involves the blanking.
Part of a signal, being the interval between the end of one line or frame and the beginning of the following one. For example, it represents the turn off of a CRT display's beam (non visible) between 2 horizontal lines (horizontal blanking) or between 2 vertical frames or fields of a picture (vertical blanking). See Reduced Blanking.
Coaxial connector that can easily be locked. These connectors are widely used for video broadcast interconnections.
Amplified output to drive heavy loads or long coaxial cables.
Device that enables long distance signal driving. Can also provide several outputs (see Distribution Amplifier).
When the audio and video signals from the same source can be separated and used independently.
Intensity of the video level being the quantity of brightness emitted by the display (offset of a visible part of the video picture).
Electronic device with a unity gain, that allows an input signal to be "isolated" from the output signal.
Technology for compensating the High Frequency quality losses in long distance cable applications.
Closed captions. Text information carried in an unused part of television signals, not applicable for computer signals. Also see EMBEDDED.

Closed Circuit TV or Closed Caption TV. See CC.
Comformité Européenne (European Compliance). CE label is assigned to a product complying with the European Union (EU) directive for EMI, RFI Interference and Safety.
Color Graphic Adaptor – Standard computer format consisting of 320 x 200 pixels. The aspect ratio is 16:10.
Color signal (RGB) whose the value will replace a video signal from another source.
Color information contained in a video signal. The chrominance is independent from the luminance. A video picture without any chrominance would be Black and White.
Push-on connector (coaxial) mainly used in Audio and Video. See RCA®.
A feature exclusive to Analog Way. Clean Cut® freezes the image during a transition and switched (CUT) by another image (Using one scaler only).
A feature exclusive to Analog Way. Clean Fade® freezes the image during a transition and dissolved (FADE) by another image (Using one scaler only).
Common Mode Rejection Ratio, ratio of useful & noise signals expressed in dB. In this case, a useful signal is "differential", noise is "common mode" (see Balanced)
Cyan, Magenta, Yellow and Black are colors used for printing. It is the opposite in Video that instead of adding colors to make white subtracts colors to make white. If C=M=Y=K=0, it is white (no ink).
The amount of color versus white brightness. "Dark Blue" is more saturated than "Light Blue"
Improved video delay line filter for separation between the Luma and the Chroma. It is called a comb filter because its frequency response looks like a comb.
Video signal (also called YUV / Y, R-Y, B-Y / BETACAM™, DVCAM™ (Sony) / MII™, DVCPRO™ (JVC, Panasonic)) widely used in broadcasting. The quality level is better than Y/C and Composite Video signals. The advantage is that the Y luminance is separated from the Chrominance U&V. The Component Video signal is transmitted with 3 coaxial cables.
Signal made of Horizontal and Vertical synchronization pulses that does not contain Chrominance and Luminance information. Sometimes it can also be called "C.SYNC", "SYNC", "COMP" (1 coaxial wire).
Video signal that combines the modulated Chrominance, the Luminance and the Sync. pulses. The signal is transmitted by a single coaxial cable. It is usually called PAL, SECAM or NTSC.
Used for On/Off remote control of basic functions. Opens or closes the circuit as a signal.
The range of the minimum and the maximum brightness values.
Also called Digital U,V.
Diaphony between luminance and chrominance in Composite video signals. Often seen on fine verticals lines of a TV set (High Frequencies transitions).
Cathode Ray Tube. Vacuum tube for displays, in which electrons are projected onto a phosphor screen to produce light and further images. This technology is used in televisions and computer monitors.
Connector generally used with computers. DB or D have 2 rows of pins (see also HD connector).
Term used to define the computer or display monitors that cannot display TV/Video signals (15 kHz). A Data monitor's starting frequency is of about 31 kHz or more (VGA, SVGA, SXGA, UXGA...).
The Display Data Channel or DDC is a collection of digital communication protocols between a computer display and a graphics adapter that enables the display to communicate its supported display modes to the adapter and to enable the computer host to adjust monitor parameters, such as brightness and contrast.
Logarithmic ratio of two "powers" or "voltage" in term of losses or gains (1/10 of a Bel). It is commonly used in Audio systems: OdB is a gain of unity and -3dB is a gain of 0.7.
Video (TV scan) device that transforms a Composite or Y/C signal into an YUV or RGB baseband, with no change in Horizontal and Vertical frequencies.
Way of coding an analog signal. A Digital signal uses sampledamplitude and Discrete Time Coding manners for example of arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. A DLP or LCD projector uses digital coding for displaying an image (Compare to ANALOG).
Deutsche Industrie Norm. Connector that exists in different versions: 4, 5, 8, etc. pins. The S.Video signal generally uses a 4 pins mini DIN (Y/C) connector. Some computer keyboards use DIN or Mini DIN connectors.
DisplayPort is a digital display interface standard produced by the Video Electronics Standards Association (VESA). DisplayPort is designed to replace Digital Visual Interface (DVI) and Video Graphics Array (VGA). DisplayPort can also provide the same functionality as HDMI but is not expected to displace HDMI in high-definition consumer electronics devices. The DisplayPort signal is not directly compatible with DVI, HDMI, or VGA. It is backwards compatible only one Single Link and never with the Dual Link (For example: DisplayPort to Dual DVI on a Radeon© HD Card). Some graphic cards don’t include few chips for the management of the DisplayPort to HDMI Port or as well the problems in the Multi-Mode management for the resolutions. (DP++ Signal). In this case, an active adaptor is always necessary.
Device enabling the signal connected to its input to be multiplied and amplified. Also enables several display devices to be connected to the same source. Also called BOOSTER or SPLITTER.
