Decoder
The sound on DVDs with home theatre sound is saved on the
DVD in encrypted (encoded) form. Different encryption formats
exist for several purposes, for example AC-3 for the playback
of Dolby Digital Surround Sound.
To playback the encrypted sound the playback device (i.e. the
DVD player) and/or the audio component connected to it (i.e.
Surround system) must have a so called Decoder that can
turn the encrypted signal back into music and/or sound.
The Silvercrest KH 6510/KH 6511 DVD player is equiped with
an AC-3 Decoder (for Dolby Digital 5.1 Surround Sound signals).
Dolby Surround
Dolby Surround is an analog audio format with which the
two channels of a stereo audio signal are used to store sur-
round sound information for an additional channel. Dolby
Surround decoders convert the signals back into sound or
music and send the audio to two additional speakers that
are situated behind the listener.
Dolby Prologic
In comparison with the Dolby Surround audio format, Dolby
Prologic uses an additional channel in the stereo signal; this
is the "center" channel. The corresponding center speaker is
situated directly between the stereo speakers. The deepest
tones are sent to a low range speaker, called a "subwoofer".
The subwoofer can be placed at any location in the room; the
reason for this is that the deep tones emitted by the subwoofer
cannot be precisely localised by the human ear.
Dolby Digital (5.1)
Dolby Digital, also referred to as AC3, is a digital audio format
with which up to six separate audio channels can be transmitted.
On most current DVDs, the audio is stored in "Dolby Digital
5.1" format; the "5" in the name "5.1" stands for the three
front and two rear surround sound channels, the "1" stands
for the subwoofer channel.
DTS
DTS is short for "Digital Theatre System" and is designated
one of the most conventional Surround Sound formats for
DVDs. As with Dolby Digital 5.1, DTS uses three front and two
rear surround sound channels as well as a subwoofer channel.
What are PAL, NTSC and SECAM?
PAL
PAL is short for "Phase Alternation Line". PAL is the typical
and most common colour television standard in Central and
Western Europe (exception: France see the heading "SECAM"),
the most wide spread and common colour television stan-
dard.

NTSC
NTSC is short for "National Television System Committee".
NTSC is a colour television standard that is used primarily
in the USA and Japan.
SECAM
SECAM is the abbreviation for the French "système en couleur
avec mémoire". SECAM is currently the typical and most com-
mon colour television standard in France and many Eastern
European countries.
Audio CDs
Audio CDs contain only audio data; they are also available
in the sizes 8 cm and 12 cm (diameter). The playback time
for the audio data stored on CDs is 20 minutes (8 cm size)
or 74 minutes (12 cm size). Audio data is stored on audio
CDs in the CDA format.
MP3
MP3 refers to a method or format for compression of audio
files developed by the Fraunhofer Institute. In MP3 format
compressed music is only a fraction of its original size, whereby,
for example, on CD-Rs/CD-RWs far more music can be stored
than on standard audio CDs, on which audio data is stored
in CDA format.
WMA
WMA ("Windows® Media Audio") is a data format develo-
ped by Microsoft® for Audio data.
JPEG
JPEG ("Joint Photographics Expert Group") refers to a widely
used graphics format developed by the organisation of the
same name, with which colour and gray scale image data are
compressed.
Nero Digital
NERO is a dta compresion program, which can compress all
video formats to less than 20% of their original size, while
still maintaining a high qualiyt. CDs, which have been recor-
ded with NERO, can contain chapters and sub-titles in two
languages. The CDs are operated via the normal buttons that
are used for DVDs. Data, which are not created with the
NERO Digital "Standard Profile", may not play immediately
or only with restrictions.
DivX
DivX is a coding format for videos and multi-medial data,
invented by DivX Networks, Inc.
MPEG
MPEG ("Moving Picture Experts Group") refers to a Video
compression format.
USB memory sticks
The term USB memory stick refers to a plugable USB device,
which is approximately the size of a cigarette lighter. The ex-
pression is only colloquial and not a designation for a type of
product. For the most part with this expression is meant a
USB device that serves as an interchangeable storage media.
