Random Access Memory
Remote Control transmitter
Remote Control system 5 (6), the
signal from the remote control receiver
Radio Data System (European); This
is an MPX signal carried in FM radio
channels (87.5 ... 108 MHz)
RESET signal
Real Flat (picture tube) or Radio
Frequency
Red, Green, and Blue colour space;
The primary colour signals for TV. By
mixing levels of R, G, and B, all colours
(Y/C) are reproduced
Red, Green, Blue, Horizontal sync,
and Vertical sync
Reduced Instruction Set Computer; A
processor architecture based on ultra-
high speed processing technology that
uses a far simpler set of operating
commands than a normal
microprocessor does
Root Mean Square value
Read Only Memory
Surround channel or mono surround
channel (audio)
System Application for Low Segment
of Analogue TV
Service Alignment Mode
Secondary Audio Program; Generally
used to transmit audio in a second
language
Surface Acoustic Wave

from sync signals
Syndicat des Constructeurs
d'Appareils Radiorécepteurs et
Téléviseurs; This is a 21-pin connector
used in EU, that carries various audio,
video, and control signals (it is also
called Péritel connector)
Scan Velocity Modulation; Advanced
beam control technology, which
results in sharper edges on all images
for outstanding clarity
