S-video
When the DVD player is connected to a television via S-video,
the brightness and colour signals are separated; this achieves
better image sharpness and less "colour noise“.
Colour noise refers to the overlaying of the colourful, usually
highly saturated parts of a video image with irregular, varia-
ble flaw patterns.
Composite video
Video signal or FBAS signal; this refers to a video signal that
contains both colour and brightness information.
Progressive scan
Normally TV sets and Video projectors with so called "Half
images" are controlled. This results in clearly visible line struc-
tures. In contrast, progressive scan refers to the supply of full
images (with this DVD player at the YPbPr output), progressi-
ve scan signals can only be processed by playback devices (pri-
marily large screen televisions, projectors) that offer this feature.
The image quality is significantly better than typical video signals.
YUV (component video out)
YUV refers to the component signal, which is available with
this device at the YPbPR output in the form of "half images";
as a rule this is the best signal for the control of large screen
televisions and projectors, which can not process Progressive
scan signals. As with RGB video signals, the YUV consists of
three separate video signals:
• the brightness signal "Y" and
• both colour difference signals "Pb/Cb" and "Pr/Cr"
Half images (interlacing) / full images (progressive scanning)
A standard television image consists of 576 visible lines; first
the odd then the even image lines are displayed in alterna-
tion. In other words, one half image is shown at a time. In
this way, only 30 full images (60 half images) can be displayed
per second. This method is referred to as "interlace" format.
Contrary to this with the so called progressive or "Progressive
scan" format all images are shown every time, that is to say
60 full images per second are displayed. This increases the
overall quality of the image; for example paused images and
text appear sharper.
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 sig-
nals).
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 for-
mat 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, in Central
and Western Europe (exception: France see the heading
"SECAM"), the most wide spread and common colour television
standard.
