Chroma – The characteristics of color information, independent of luminance intensity. Hue and saturation are qualities of chroma. Black, gray, and white objects do not have chroma characteristics.

Chrominance Signal – Part of a television signal containing the color information. Abbreviated by “C”.

Coaxial Cable – A two-conductor wire in which one conductor completely wraps the cable.

Component Video – Our color television system starts with three channels of information; Red, Green, & Blue (RGB). In the process of translating these channels to a single composite video signal they are often first converted to Y, R-Y, and B-Y. Both 3-channel systems, RGB and Y, R -Y, B -Y are component video signals. They are the components that eventually make up the composite video signal. Much higher program production quality is possible if the elements are assembled in the component domain.

Composite Sync – A signal consisting of horizontal sync pulses, vertical sync pulses, and equalizing pulses only, with no signal reference level.

Composite Video – A mixed signal comprised of the luminance (black and white), chrominance (color), blanking pulses, sync pulses and color burst.

Contrast – The range of light and dark values in a picture or the ratio between the maximum and the minimum brightness values. Low contrast is shown mainly as shades of gray, while high contrast is shown as blacks and whites with very little gray. It is also a TV monitor adjustment which increases or decreases the level of contrast of a televised picture.

Crosstalk – Interference from an adjacent channel which adds an undesirable signal to the desired signal.

Crosstalk Isolation – Attenuation of an undesired signal introduced by crosstalk from an adjacent channel.

CRT Cathode Ray Tube – A vacuum tube that produces light when energized by the electron beam generated inside the tube. A CRT has a heater element, cathode, and grids in the neck of the tube, making up the “gun”. An electron beam is produced by the gun and is accelerated toward the front display, or screen surface of the tube. The display surface contains phosphors that light up when hit by the electron beam. The CRT is more commonly known as picture tube.

dB Decibel – The standard unit used to express gain or loss of power. It indicates the logarithmic ratio of output power divided by input power. A power loss of 3 dB is an attenuation of half of the original value. The term “3dB down” is used to describe the “half power point”.

DC Direct Current – The flow of electrons in one direction.

D Connector – A connector with rounded corners and angled ends, taking on the shape of the letter “D”. Commonly used in computers and video.

Decibel – See dB.

Decoder – A device used to separate the RGBS (Red, Green, Blue and Sync) signals from a composite video signal.

Differential Audio – See Balanced Audio.

Distribution Amplifier (DA) – A device that allows connection of one input source to multiple output sources such as monitors or projectors.

FCC – Federal Communications Commission – A unit of the U.S. Government that monitors and regulates communications.

Field – In interlaced video, it takes two scans on a screen to make a complete picture, or a “Frame”. Each scan is called a “Field”. Sometimes these are referred to as “field 1 and field 2”.

Flicker – Flicker occurs when the electron gun paints the screen too slowly, giving the phosphors on the screen time to fade.
