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 filter2)

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.
