Video Setup
Optimum picture quality is only possible if the picture
norms of all the video components in the system are set
up to match each other, and if the correct cables
(SCART, video-coax) for the selected picture norm are
used. In the
'Video Setup'
you can set the picture norm
for all the decoder’s video inputs and outputs to match
the capabilities of the devices connected to it. Many AV
source devices can generate a picture signal using dif-
ferent picture norms (Video, S-Video, RGB), and in this
case the picture norm you wish to use must often be set
in a menu on the AV source device. If you are not sure of
this, study the operating instructions supplied with the
source device and the TV set.
There is a large number of different picture norms on the
market, but not all of them are supported by all AV
source devices and TV sets. The decoder is designed to
handle the most widely used picture norms: Video, S-
Video and RGB; RGB provides the best picture quality.
The least problematic arrangement is for all the compo-
nents to use the same picture norm. If the TV set con-
nected to your surround system has a priority RGB cir-
cuit, mixed operation is also possible (e.g. DVD player

RGB, Set-top box
«
Video; VCR
«
S-Video);

TV out:
RGB / Video
For TV sets with RGB or Video sock-
ets.
S-Video
For TV sets with S-Video sockets.
DVD in:
RGB / Video
If the DVD supplies an RGB and Video
signal.
S-Video
If the DVD supplies an S-Video signal.
Set-top in:
RGB / Video
If the set-top box supplies an RGB and
Video signal.
S-Video
If the set-top box supplies an S-Video
signal.
VCR in:
Video
If the video recorder
only
supplies a
Video signal
S-Video
If the video recorder supplies an S-
Video signal
Example:
In the example mentioned above, the
TV out
output
should be set to
RGB / Video
. The decoder automati-
cally converts the incompatible S-Video signals to the
Video format.
Note:
Some AV source devices make available a switch volt-
age at their SCART output which switches the TV set
connected to it from television reception to SCART pic-
ture and sound reproduction; it can also be used to
change the picture format (4:3 / 16:9). Different makes of
TV set interpret the switch voltage in different ways; see
your TV operating instructions for details.
•
In
RGB/Video
mode the switch voltage produced by
the source device is passed on to the TV out socket
unchanged.
•
In
S-Video
mode the decoder switches on the switch
voltage at the TV out socket permanently.
If compatibility problems arise between the TV set and
the AV source devices connected to the system, we
recommend that you use the standard Video norm for all
the machines, as this is generally supported by all de-
vices. Look at
