Source numberThe source number of a non-active file can be changed to any other source number. This makes it
possible to create a file for future source numbers.
Clamp positionClamping determines the black level of the signal. The clamp pulse can be related to the leading or
the trailing edge of the sync pulse. Use theENTERkey to toggle between [leading] and [trailing].
Clamp delayThe time between the leading edge of the clamp pulse and the locked edge of the sync pulse. Can be
any value between 0 and 255. Change the value by pushing the cursor key↑or↓.
Clamp widthThe width of the clamp pulse can be any value between 0 and 255. Change the value by pushing

Field polarityThe field polarity function is used for interlaced images. Both rasters of the image could be shifted in a
wrong way (double lines are visible in the image). This can be corrected by forcing the field polarity to
[neg] or [pos]. Use theENTERkey to toggle between [pos] and [neg].
Field selectDefault [both]
The field select is only used for interlaced images. One frame of an interlaced image contains two
fields, an even and an odd field. The choice exists to project [both] fields on the screen or only the
[even] or [odd] field. This can be useful for 3D projection. Use theENTERkey to toggle between
[both], [even] and [odd].
Vertical refresh
[sync/async]The way of updating the image information. Not available for PAL-NTSC-SECAM sources. This
option will be displayed in gray.
• For sources with a vertical frequency up to 60 Hz :the vertical refresh rate is the same as the
vertical frequency of the incoming source. This is a necessity to project moving images without
’motion artifacts’. For stationary images with a vertical frequency up to 60 Hz it is still possible
to use asynchronous refresh. When loading Pal, Secam, NTSC-files the synchronous mode is
default, for all other sources below 60 Hz asynchronous mode is default.
• For sources with a vertical frequency higher that 60 Hz : the vertical refresh is different than the
vertical frequency of the incoming source. Synchronous refresh cannot be used.

Film mode detection:
[On] or [Off]Detects in the [on] mode if the source is film or video. Use theENTERkey to toggle between [on] or [off]
When enabled, the hardware looks for tell-tale signs of 3:2 or 2:2 pull-down sequences. These are the
result of converting cinema material recorded at 24 frames-per-secondto the television frequencies of
60 or 50 interlaced fields per second respectively. When FILM conversion is detected, the original
24 frames-per-second are restored. This avoids deinterlacing artefacts, and results in a perfect
artefact-free display. Note that in some cases (video clips, scrolling newstickers,...) FILM and VIDEO
material are mixed on one screen. This may confuse the detector and cause it to go into FILM
restoration mode. This will cause jaggies or motion artefacts. In such cases, disabling FILM mode
processing is the best cure.
Banner Protect: [On]
or [Off]Only active when film mode detection is in the on position. Use theENTERkey to toggle between
[on] or [off].
FILM mode processing normally processes the entire display, but this may cause problems on sources
where video and FILM content are mixed. One very common example is scrolling banners at the
bottom of the screen (e.g. financial news). For those cases, the banner protect feature will force the
bottom quarter of the screen to be always processed in VIDEO mode, regardless of the rest of the
screen, which may be either video or FILM mode.
3:2 pull-down
Method used to map the 24 fps of film onto the 30 fps (60 fields) or 25 fps (50 fields), so that one film frame occupies
three video fields, the next two, etc. It means the two fields of every other video frame come from different film frames
making operations such as rotoscoping impossible, and requiring care in editing. Some sophisticated equipment can
unravel the 3:2 sequence to allow frame-by-frame treatment and subsequently re-compose 3:2. The 3:2 sequence
repeats every five video frames and four film frames, the latter identified as A-D. Only film frame A is fully on a video
frame and so exists at one time code only, making it the editable point of the video sequence.
2:2 pull-down
The process of transferring 24-frames/sec film format into video by repeating each frame (used for PAL DVD’s) as two
video fields. ( AD )
Artefacts
Undesirable elements or defects in a video picture. These may occur naturally in the video process and must be
eliminated in order to achieve a high-quality picture. Most common in analog are cross color and cross luminance.
Most common in digital are macroblocks, which resemble pixelation of the video image.

7.3.4 Color Space
Color space
A color space is a mathematical representation for a color. For example, the RGB color space is based on a Cartesian
coordinate system.
What can be adjusted ?
The color space (gamut), the collection of colors which can be reproduced by the projector, can be adjusted to 3 predefined stored
values (one projector specific and 2 international standards). Acustom adjustment is possible. The maximum color space which
can be displayed is the projector color space. This color space is measured at the factory and stored inside the projector.

7.3.6 Input Balance
Why adjusting theinput balance?
The input balance is normally correct adjusted in the factory. But dueto signal distribution or signal transmission, a color imbalance
can be the result. This imbalance can be adjusted source by source for color critical applications. These adjustments influence only
the actual custom adjustment file. This procedure is not so easy.
There are 2 different adjustment procedures, one for RGB (included Video and S-Video) and one for YUV input
signals.
Before starting the Input Balance function, generate a signal with dominant black and white areas.

7.3.6.1 Input Balance for RGB input signals
Step to be taken for RGB input signals
To adjust the input balance, the following steps have to be executed in the following order :
1. Start with the black balance.
2. Continue with the white balance.
The default values are normally loaded when selecting a source. If the image is not as desired, continue with
the next procedure.
