Bandwidth The range of frequencies used to transmit information such as picture and sound.
Baseband Video An unmodulated video signal.
BG An unmodulated video signal.
Black Also color black, blackburst. A composite color video signal that has the composite sync, reference
burst, and a black video signal.
Blanking Processor A circuit which removes sync, burst and blanking from the program video and then
replaces it with sync, burst and blanking from the reference input. The process ensures constant sync
and burst levels on program video.
Border An electronically-generated picture member that is used in wipes to separate the two video
sources used in the wipe. It is of even thickness and has color produced by the matte generator.
Broadcast Legal Encoding video signal parameters to conform to prescribed limits for broadcast.
Encoding rules vary by NTSC, PAL, country and broadcast facility.
BTSC Broadcast Television Standards Committee. A US standard for stereo audio encoding in NTSC
broadcast television.
CAV Component Analog Video
CDP Caption Distribution Packet
CES Consecutive Errored Samples
Composite Video A single video signal that includes all color video and timing information. A composite
signal includes luminance, chrominance, blanking pulses, sync pulses and color burst information.
Chrominance The color portion of a video signal that represents the saturation and hue. Black, gray and
white have no chrominance; color signals have both chrominance and luminance.
CH Chroma
Chrominance/Luminance Delay (C/L Delay) A measurement that indicates the amount to which
chrominance and luminance are aligned with respect to each other. A low C/L delay figure can minimize
the effects of ghosts or color offset on the received picture.
Clipping The electronic process of shearing off the peaks of either the white or black excursions of a
video signal for limiting purposes. Clipping is often performed prior to modulation to limit the signal.
CMRR Common Mode Rejection Ratio
Color Burst The portion of a color video signal which contains a short sample of the color subcarrier. It is
used as a color synchronization signal to establish a reference for the color information following it and
is used by a color monitor to decode the color portion of a video signal. The color burst acts as both
amplitude and phase reference for color hue and intensity. The color oscillator of a color television
receiver is phase locked to the color burst.
Composite Sync A signal consisting of horizontal sync pulses, vertical sync pulses and equalizing pulses
only.
