VIDEO 3 IN loop-through output
Set the VIDEO 3 IN selectors as follows:
•

Using the line doubler
The line doubler function of this unit converts the input NTSC
or PAL signal into a digitally interpolated, high scan-rate
output signal. The output signal format becomes a non-
interlaced signal whose horizontal frequency is 31.5 kHz and
vertical frequency is synchronized to the input signal.
The line doubler up-converts the signal field by field by
interpolating information on two line signals vertically.
Therefore, a fast moving picture is reproduced as a natural
high-resolution picture.
• The converted signal is output from the RGB/component
output connector in the RGB format.
• The line doubler can be activated for the three inputs
separately.
Activating the line doubler
1
Press the OUTPUT FORMAT button to select 31.5k.
2
Connect a NTSC or PAL signal source and select the
input with the INPUT SELECT buttons.
3
Press the LINE DOUBLER button.
The indicator of the button lights, and the NTSC and 31.5k
or the PAL and 31.5k OUT indicators light.
