care to observe the correspondence with the outputs on the
source. The video signals that can be connected to this input
can have horizontal scanning frequencies of 15 kHz (standard
video resolution), 32 kHz, or higher (progressive scanning
video, high definition video).
Some sources provide the facility to choose between a pro-
gressive signal or an interlaced signal. Although in general a
progressive signal is higher quality than an interlaced signal,
it is often preferable to perform the deinterlacing operation on
the projector rather than on the source because the projector is
equipped with Faroudja’s sophisticated directional correlation
deinterlacing technology (DCDi™).
HDMI™ INPUT
With this input it is possible to integrate the optimal quality of a
digital image with a multichannel audio signal.
The HDMI™ (High Definition Multimedia Interface) in fact in
-
tegrates a multichannel audio signal with the uncompressed
high definition video signal.
The interface also allows the exchange between the video
source and the HT system of control data to optimise the
quality of the projected image.
The HDMI™ input allows connection to video sources that use
the HDCP (High-Bandwidth Digital Content Protection) protocol
to protect their contents. This protocol is in fact incorporated in
the definition of the HDMI™ technology.
Once the video source has been connected to the HDMI™
input, internal processing by the projector separates the video
information from the audio information. This information is then
made available via an optical digital output with a female TO
-
SLINK connector in accordance with the S/PDIF standard.

The projector is equipped with two outputs (Voltage: 12 Vdc) for
motorised projection screen and screen masking systems. The
-
se 12V outputs should be connected to the appropriate screen
interface provided by the screen manufacturer
(Fig. 22).
The +12V output is activated when the projector is switched
on (green LED on) and is de-activated when the projector is in
stand-by mode (red LED on).
The output
can be used to control a screen masking system;
its output can be set with the Screen control adjustment in
the
Aspect menu. This output allows reduction in the area of
a 16:9 screen, into a 4:3 format, by activating a screen masking
system (refer to screen manufacturer for further information).
