AV programme position
AV devices have one or more sockets, depending
on the model. These sockets are labelled on the
device, for example with AV1.
These sockets can be selected on the AV device
and the selected socket is shown on the display of
the AV device, for example A1 for socket AV1.
Code
The settings for the childlock are protected by a 4-
digit numerical code which you can set a desired.
Write down or remember the code you define. If
you forget the code, ask your local dealer for assi-
stance
CTI
The CTI (Colour Transient Improvement) circuit is
an electronic circuit which ensures precise transi-
tions between differently coloured parts of the pic-
ture, preventing the colour smearing which could
otherwise occur. The CTI function is active for pro-
grammes received via the antenna input and for
picture signals from AV devices.
Comb filter
2)
In conventional TV sets, the luminance signal and
the chrominance information are separated from
each other with a frequency separating filter.
However, this means that a certain amount of the
luminance signal is still included in the colour sig-
nal and can cause interference (cross-luminance)
and that a certain amount of the colour signal
causes interference in the luminance signal (cross-
colour). The comb filter prevents these problems.
Just like a comb, this filter extracts the colour sig-
nal, which is located in the gaps of the luminance
signal, without affecting the bandwidth of the
luminance signal. The result is a TV picture with
the maximum possible resolution and without
cross-colour or cross-luminance interference.
2) Available only on TV sets
which are equipped with this
option.
