Options
Source number : The source number of a non-active source can be
changed to any other source number. This makes it possible to
create a file for future source numbers.
Clamp position : Clamping 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 the ENTER key to toggle between [leading] and
[trailing].
Clamp delay : The time between the leading edge of the clamp pulse
and the locked edge of the sync pulse.
Can be any value between 0 and 127. Change the value by pushing
the control stick to the left or to the right.
Clamp width : The width of the clamp pulse
Can be any value between 0 and 127. Change the value by pushing
the control stick to the left or to the right.
Field polarity : Default [auto]
[auto] = autodetection of the field polarity.
The field polarity function is used for interlaced images. Both rasters
of the image could be shifted in a wrong way (double lines are visilble
in the image). This can be corrected by forcing the field polarity to
[neg] or [pos].
Use the ENTER key to toggle between [auto], [pos] and [neg].
Field select : Default [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 the ENTER key to toggle between [both], [even] and [odd].
Vertical refresh [sync/async] : The way of updating the image
information on the LCD panels. For moving images, the vertical
refresh has to be done on a synchronous way, for still images,
asynchronous vertical refresh is possible.
Vertical sync polarity : [leading] or [trailing]
The vertical refresh can be synchronised with the leading sync edge
or trailing sync edge. Default on [leading].
Toggling to [trailing] is only necessary for special applications where
the trailing edge of the sync signal has to be taken as a reference.
Use the ENTER key to toggle between [leading] or [trailing]
Press EXIT to leave the Edit File Option menu.
A 'Confirm Edit File' menu will be displayed.
