IC Integrated Circuit
IF Intermediate Frequency
IIC Inter IC bus (also called I2C)
Interlaced Scan mode where two fields are used
to form one frame. Each field contains
half the number of the total amount of
lines. The fields are written in "pairs",
causing line flicker.
IO In/Out
IR Infra Red
L Left audio channel
L/L’ Monochrome TV system. Sound
carrier distance is 6.5 MHz. L' is Band
I, L is all bands except for Band I
LATAM LATin AMerica
LED Light Emitting Diode
LOT Line Output Transformer (also called
FBT); The transformer in which the
EHT is generated

Progressive Scan Scan mode where all scan lines are
displayed in one frame at the same
time, creating a double vertical
resolution.
PTC Positive Temperature Coefficient, non
linear resistor (resistance increases if
temperature increases)
PWB Printed Wiring Board (also called PCB
or CBA)
