Automatic zoom
When the automatic zoom function is active, pro-
grammes broadcast in "widescreen format" (such
as those in the 16:9 format) are expanded to fill
as much of the screen as possible.
If this function is inactive, the format of such pro-
grammes is not adjusted automatically.
AV programme position
AV devices have one or more connection sockets,
depending on the model. The designations of the-
se sockets are marked on the device (e.g. AV1).
On the AV device, you can select which socket
you want to use. The selected socket is shown on
the display of the AV device (e.g. A1 for socket
AV1).
Code
The settings for the childlock function are protec-
ted by a four-digit code: you can enter any des-
ired code, but you should note it for future use. If
you have forgotten your code, please consult your
local dealer.
Comb filter
2)
In conventional TV sets, the brightness signal is
separated from the colour information with the aid
of a frequency filter.
However, such a filter cannot prevent a certain
amount of the brightness signal from being mixed
with the colour signal, causing interference (so-
called cross-luminance interference). Similarly a
certain amount of the colour signal is mixed with
the brightness signal (so-called cross-colour inter-
ference). The comb filter does away with these
shortcomings. Just like a comb, it extracts the
colour signal (which is carried in the gaps of the
brightness signal) without affecting the bandwidth
of the brightness signal.
2) Possible only on sets equipped with this
function.
