AV source device
A source device which supplies sound and picture sig-
nals. The sound signals may be generated in analogue
or digital form.
Center
Front loudspeaker between the two main speakers, lo-
cated below or directly adjacent to the TV set.
dB
The unit of measurement for electrical levels is the deci-
Bel (dB).
DSP (Digitaler Signal Processor)
The digital surround decoder employs a fully program-
mable signal processor. A DSP can process signals
using a program stored in the program memory. The
program can be updated at any time, which means that
the decoder can be kept abreast of new developments.
Front-speaker
Front pair of main loudspeakers, set up to left and right
of the television set.
Surround-speaker
Rear pair of loudspeakers, set up behind the listening
position, designed to provide spatial sound effects.
R
LINK
Universal control interface by means of which all the
components of a
system communicate, provided
that they are fitted with an R
RGB
High-quality picture norm, utilising separate wires for the
colour signals red, green and blue. This avoids the
problem of signal contamination; RGB playback pro-
vides the best possible picture quality.
SCART
Widely used standardised connection using a 21-pin
connector. SCART leads can transfer all picture norms
and additional control signals (e.g. for 3:4 / 16:9 picture
format switching). Adaptors are available in specialist
shops for connecting a SCART socket to other standard
connectors (Cinch or Hosiden).
Glossary
control socket.

STANDBY
The digital surround decoder can be switched on from
stand-by mode at any time by pressing a button on the
remote control handset.
Subwoofer
Loudspeaker designed for reproducing low bass signals.
It is used for special deep bass effects which are en-
coded on the LFE channel in Dolby Digital and dts mate-
rial. When combined with small satellite speakers they
also provide a full-range bass response.
S-VIDEO
High-quality picture norm with separate brightness and
colour signals. Better picture quality than standard video.
However, as the colours are not transmitted separately,
picture quality is not quite as good as with the RGB
method.
TASI
This standard
interface makes it possible to loop a
surround decoder between the source selector
switch and the volume control of the stereo amplifier. The
interface automatically detects the decoder when it is
connected. In surround mode the volume and tone con-
trols of the stereo amplifier are disabled, as these func-
tions are assumed by the decoder.
Update
Method of bringing the software used by the decoder's
main processor or signal processor abreast of new de-
velopments. Updating the software provides for future
expansion of functions and changes to meet new re-
quirements.
VIDEO
Standard picture norm: colour and brightness information
is transmitted by a single conductor. Standard video
connections are present on all AV devices.
