Read AMDS
AMDS = automatic mode detection & synchronisation
During the installation of a file with LOAD, the system automatically measured the horizontal period, the total vertical lines and the interlaced
mode.
When selecting Read AMDS, the system remeasures the above indicated items.
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 255. Change the value by pushing the
cursor key è or ç.
Clamp Width : The width of the clamp pulse
Can be any value between 0 and 255. Change the value by pushing the
cursor key è or ç.
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 visible in the
image). This can be corrected by forcing the field polarity to [neg] or [pos].
Use the ENTER key to toggle between [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 informa-
tion on the LCD panels.
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.
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]
