RGSB - YSCRCBCOMPONENT VIDEO
Fig. 20
This input is suitable for a RGB video signal, or for a Component 
(YCrCb)  type,  with  composite  synchronisation  on  the  green 
signal (RGsB) or on the luminance (Y) signal (YsCrCb) through 
a cable with RCA/Phono type connector (Fig. 20).
RGB  or YCrCb signals can also have  H+V Composite Sync.
In  this  case  connect  the  R,  G,  B  (or  Y,  Cr,  Cb)  outputs  of  the 
source to the respective R/Cr, G/Y, B/Cb inputs of the projector 
(paying attention not to invert the positions) and the synchroni
-
sation signal to the HV input . When connecting the three sets 
of RCA connectors use the colours as a guide: connector R is 
red, G is green, B is blue and  HV is white.  By using a suitable 
SCART to RCA  connector adapter cable, an RGB video signal 
from  a  source  equipped  with  an  SCART  connector  can  be 
connected to this input.
Component signals are connected to inputs Y, Cr and Cb, taking

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).

of black objects alongside other dark coloured objects.
CONTRAST
Use  this  control  to  adjust  the  image’s  black  level  without  af-
fecting white areas.To ensure correct adjustment, it may prove 
useful  to  display  the  signal  relative  to  the  grey  scale,  within 
which the white level and the level immediately below it must 
be separately identifiable. Alternatively use a scene composed 
of  well-lit  white  objects  surrounded  by  light  coloured  objects 
with lower level lighting. 
COLOR
This control (also called Saturation) increases or decreases
the  picture  colour  intensity.  When  set  to  zero,  colour  images 
 
will  be  shown  in  black  and  white.  Increasing  the  value,  try  to 
 
find the point at which the colours look natural: suitable referen

re,  increasing  the  value  will  boost  the  green  tones.  For  this 
adjustment use skin tones or a test pattern image with colour 
 
bars as a reference. 
SHARPNESS
Use  this  adjustment  to  increase  and  decrease  the  level  of  
picture detail. 
When  the  sharpness  value  is  reduced  the  image  details 
 
appear  less  pronounced,  while  increasing  the  value  raises 
 
image definition, making the outline of objects sharper. 
Note that an excessively high value may result in a ‘noisy’ picture 
and the edges of objects may be unnaturally defined.
SHARPNESS MODE
This  allows  you  to  select  the  type  of  processing  associated  
with sharpness adjustment. In the case of a progressive or in
-
terlaced video signal 
VIDEO mode is advisable; with PC graphic 
signals use GRAPHIC MODE.
FILTER
This  allows  you  to  select  the  mode  in  which  the  input  signal  
is processed. Selecting the most appropriate value for a given 
input signal ensures the best horizontal and vertical definition 
and makes the picture sharper. 
These submenus are accessed by pressing the fl key, while  
exit and return to the upper level occurs by pressing 
MENU+/-. 
Press 
ESC  on  the  remote  control  or  keypad  to  interrupt  the

CINEMA MODE
In AUTO the deinterlacer recognises if the video signal source  
is a movie film (obtained from a Telecine device with 3:2 or 2:2 
pull-down)  and  applies  a  deinterlace  algorithm  optimised  for 
this type of signal.
If  the  video  signal  source  is  not  identified  as  a  film,  or  if  you 
select NO  the  deinterlacer  applies  a  Motion  compensated  al-
gorithm optimised for video camera signals.
VIDEO TYPE
Activates  a  filter  to  improve  stability  of  pictures  from  video 
recorders.  To  toggle  between 
NORMAL,  VCR1  mode  and VCR2 
mode press 
  on the remote control. 
NOISE  REDUCTION
This  adjustments  allows  to  choose  the  filter  value  for  noise 
reduction purposes.
As  soon  as  this  option  is  selected  on  the  menu,  the  image  is 
divided in two parts. In the left side the image is not altered by the filter, in the right 
part the filter is activated.
This allows you to compare the effect of the filter.
It  is  possible  to  deactivated  the  filter  (
NOT  ACTIVE),  to  use  the 
automatic  adjustments  (
AUTO)  or  to  manually  select  (MANUAL) 
the value suitable for the image with the VALUE adjustment.
In  case  of  using  the 
VALUE  adjustement,  it  is  enoght  to  select 
to cursor below and set the value with the 
fl / ‡ keys of the 
remote control.
Associated  to  the 
NOISE  REDUCTION  there  is  the  possibility  to 
use  the  specific  function 
(FLESH  TONE  CORRECTION)  to  make 
skin  tone  more  natural.  Often  the  use  of  noise  reduction  filter 
slightly degrades the image in those areas where skin tones are 
visible. With the use of this function it is possible to maintain an 
excellent image quality throughout the entire projected image.

IMAGE
This  menu  features  adjustments  relating  to  picture  position, 
aspect ratio, etc.
ASPECT
This  adjustment  allows  you  to  change  the  dimensions  and 
aspect  ratio  (relationship  between  width  and  height)  of  the 
displayed image. There are five preset aspects available and 
three  personalised  aspects  (with  user-settable  parameters). 
You can select a different aspect for each source: the selected 
aspect ratio will be automatically called the next time the relative 
source is called.
You  can  also  select  the  required  aspect  ratio  by  repeatedly 
pressing the
  key, or by pressing  and a numerical key 
(1...8). The following aspects are available.
NORMAL:  projects  the  image  occupying  the  full  height  of  the 
screen  while  maintaining  the  aspect  ratio  of  the  input  signal. 
When the input signal aspect ratio is 4:3 black vertical bands 
are displayed on the right and left of the picture.
ANAMORPHIC: allows a 16:9 picture to be displayed correctly.
LETTERBOX: serves to display 4:3 letterbox image (with source 
signal having black bands above and below the picture) so that 
it fills the 16:9 screen and maintains the correct aspect ratio. 
PANORAMIC: this aspect stretches the 4:3 image, slightly crop-
ping the upper and lower parts.
Panoramic is ideal for displaying a 4:3 image on the 16:9 screen 
of the Display.
 
PIXEL TO PIXEL: this aspect displays the image as it is input without 
adapting it to the screen. 
The image is projected in the centre of the screen and if its ho
-
rizontal and/or vertical dimensions are smaller than the display, 
it is bounded by vertical and/or horizontal black bands.
USER 1, 2, 3:  When none of the preset formulas are suitable, the 
User  formulas  are  available,  with  the  facility  for  continuous 
horizontal and vertical adjustment of picture size. 
SCREEN CONTROL
For  each  aspect  chosen,  the  SCREEN  CONTROL  command 
allows  you  to  reframe  the  screen  to  a  variety  of  aspect  ratios 
and screen size, using an appropriate screen-masking interface 
connected to the 12 V output socket (please refer to the screen 
manufacture’s manual)
COLOR TEMPERATURE
The color temperature adjustment is made by positioning  the 
white point inside CIE cromaticity diagram.
The systems allows to choose from 36 predefined white points  
inside the neutral color area 
(Fig.29).

The correlated color temperature varies  along horizontal lines,  
low temperatures are present in the right side (where the red 
component  is  increased),  in  the  left  side  of  the  diagram  you 
can  find  high  temperature  values  (  in  which  blue  component  
is  higher).  The  points  along  the  lower  horiziontal  line 
(Fig.30) 
represent colors that  belong to the black body curve.

Along  vertical  lines  the  color  temperature  is  constant  but  is  
different    from  black  body  curve,  which  mean  if  you  select 
point from the high part of the  diagram you increase the green 
componet,  while  low  part  of  diagram  cause  an  increase  of 
purple component.
GAMMA CORRECTION
Determines the system’s response to the grey scale, emphasi-
sing or attenuating the different grades of brightness (blacks, 
dark, medium, light grey, whites) in the projected image. 
There  are  availabel  up  to  12  degamma  curves,  using  these 
curves it is possible choose the best curve for the signal  and 
the image in use.
OVERSCAN
Remove  noise  around  image.  Some  sources  can  produce  a 
picture with noise along edges, thanks to the overscan function 
it is possible to drop such imperfections outside the projected 
area.  The  overscan  value  can  be  included  between  0  (no 
overscan)  and  32  (maximum  value).  The  image  maintains  in 
any case the aspect.
POSITION
Use  this  adjustment  to  position  the  image  vertically  and  ho-
rizontally. Determines the aspect ratio of the projected image.
These parameters do not normally require adjustment because 
the system checks the input signal and automatically sets the
most suitable values. 
However, if the image is not perfectly centralised it may prove 
useful to request the system to repeat the input signal analysis  and image positioning, calling the automatic control procedure 
from the AUTO button on the remote control or keypad. When 
this procedure is called it is helpful to have a white or light co
-
loured background on the screen in the current picture. 
FREQUENCY/PHASE
These  adjustments,  available  for  progressive  signals  and  for 
signals from PC, ensure correspondence  between the number 
of pixels making up the signal and the number of pixels making 
up the projected image.
These parameters do not normally require adjustment because 
the system checks the input signal and automatically sets the 
most suitable values. 
However, if the image appears disturbed (loss of position within 
the  equidistant  vertical  bands  or  instability  and  lack  of  shar
-
pness  on  the  narrow  vertical  lines)  it  may  help  to  prompt  the 
system  to  repeat  the  input  signal  analysis  and  determination 
of  the  best  parameters  by  calling  the  automatic  adjustment 
procedure  with  the 
AUTO  key  on  the  remote  control  or  on  the 
keypad. 
If the automatic procedure fails to have the required effect, enter 
the  frequency  and  phase  values  manually  and  approach  the 
screen sufficiently to observe the effects of the adjustments.
Y / C DELAY
In the case of Video and S-Video signals, it may be necessary 
to correct horizontal colour misalignment within the projected 
image. For a given video standard (e.g. PAL or NTSC) the stored 
value does not normally require further fine-tuning, unless the 
source or connection cable has changed.
