Circuit Descriptions, Abbreviation List, and IC Data Sheets
2 Carrier Sound. Analog stereo sound
system used, e.g., in Germany.
NTSC 4.43; Sound carrier is on 5.5
MHz.
Audio / Video. Video is CVBS.
Analogue to digital converter
Scaler chip manufacturer
Automatic Frequency Control.
Automatic Gain Control: algorithm that
controls the video input of the feature
box
Amplitude Modulation.
Monochrome TV system. Sound
carrier = 5.5 MHz. Also system H
(Belgium) is included.
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.
Board Level Repair
Broadcast Television Systems
Committee. Multiplex FM stereo sound
system. Originating from USA and
used, e.g., in LATAM and AP-NTSC
countries.
Component Level Repair
Composite Video Blanking and
Synchronization
Component Video Input
Monochrome TV system. Sound
carrier = 6.5 MHz.
Digital to analogue converter
Electrically Erasable and
Programmable Read Only Memory
East West, related to horizontal
deflection of the set
External (source), entering the set via
SCART or Cinch. Can either be Ext.1
or Ext.3
Frequency Modulation.
Early European broadcasting
standard for high-definition television,
proposed in the late sixties and
abandoned in 1993.
Monochrome TV system. Sound
carrier = 6.0 MHz.
Integrated IC bus
Intermediate Frequency
Light Emitting Diode.
Monochrome TV system, Sound
carrier = 6.5 MHz (France), L' is Band
I, L is all bands except for Band I
Loudspeaker
Monochrome TV system. Sound
carrier = 4.5 MHz.
Main Control Unit
Not Connected
Near Instantaneous Compounded
Audio Multiplexing. This is a digital
sound system, mainly used in Europe.
National Television Standard
Committee. Colour system mainly
used in North America and Japan.
Colour carrier NTSC M/N = 3.579545
MHz, NTSC 4.43 = 4.433619 MHz
(this is a VCR norm, it is not
transmitted off-air)
Non Volatile Memory: IC containing
TV related data e.g. alignments
Open Circuit
On Screen Display
PAL Phase Alternate Line. Colour system
used mainly in Western Europe (PAL
= 4.43361875 MHz) and South
America. (PAL M = 3.57561175 MHz;
PAL N = 3.58205625 MHz).
PB Play Back. Some colour systems
cannot be received on air. The sound
carrier is on a different frequency.
However via External (PB) the sound
is offered in base-band, so via Ext. the
picture and sound are O.K.
PCB Printed Circuit board
PFC Power Factor Correction
PLL Phase Locked Loop. Used for e.g.
FST tuning systems. The customer
can give directly the desired
frequency.
QSS Quasi Split Sound. Sound IF
application used for stereo sound.
RAM Random Access Memory
RC Remote Control handset
RC5 Remote Control code standard.
RGB Red, Green, and Blue video signals
ROM Read Only Memory
S/C Short Circuit
Scart Peri television interconnection 42-pin
or 21-pin euro connector
SCL Serial Clock
SECAM Colour system used e.g. in France.
Colour carriers: F0R = 4.40625 MHz;
F0B = 4.25000 MHz
SIF Sound Intermediate Frequency
SRGB A Standard RGB (Red Green Blue)
colour space, created by Hewlett-
Packard and MicroSoft.
TBF To Be Fixed.
Tint By the user selectable white tones for
different colour temperatures.
TXT Teletext.
UOC Ultimate-One-Chip; all important
functions in one package.
uP Microprocessor.
XTAL Quartz crystal.
YC Luminance (Y) and Chrominance (C)
signal.
