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).
