Abbreviation List
2CS
2 Carrier Sound. Analog stereo sound
system used, e.g., in Germany.
4.43
NTSC 4.43; Sound carrier is on 5.5
MHz.
A/V
Audio / Video. Video is CVBS.
ADE
Scaler chip manufacturer
AFC
Automatic Frequency Control.
AGC
Automatic Gain Control: algorithm that
controls the video input of the feature
box
AM
Amplitude Modulation.
B/G
Monochrome TV system. Sound
carrier = 5.5 MHz. Also system H
(Belgium) is included.

Black Stretch
The lowest value of the video signal is
measured during the scanning time.
The black stretch shifts this level to the
nominal black level within limits.
