How to find the correct values for the displayed item?
During the installation of a file with LOAD, the horizontal period, the total number of vertical lines
and the interlaced mode are automatically measured and filled in the menu table. These values will
be available when starting up the
EDIT procedure of an active file.
Do not adjust these settings on an active file, they are used to identify the input
source file.
If the value for Horizontal Total Pixels is wrong, sampling mistakes (small vertical bars in the
projected image) will be seen in the image. Select
Total and adjust the pixel quantity. Adjust for
zero bars (hint: if the number of bars increase, adjust in the other direction).
The
Active Pixels determine the width of the window on the screen. This value is normally given
in the source specifications. If not, adjust until full image is displayed (no missing pixels).
Horizontal Start gives the number of pixels between the beginning of the input signal and the start
of the video information in the signal.
The
Horizontal Period is already filled in with the correct value of the active file.
The
Vertical Total Lines are already filled when an active file is selected to be edited.
Active Lines is the number of horizontal lines determining the height of the projected image. This
value is normally given in the specification of the source. If not, adjust until full image height is
displayed (no missing lines)
Vertical start gives the number of lines between the start of the input signal and start of the image
on the screen.
Interlaced [On] or [Off]: this selection is automatically filled when active file has to be edited. If
the image is wrong due to mismeasurement, use the
ENTER key to toggle between [On] and [Off].
(for interlaced images, one frame contains two fields).
Read AMDS (AMDS = automatic mode detection & synchronization): 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 re-measures 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 lead-
ing 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
right or left.
Clamp Width
The width of the clamp pulse. Can be any value between 0 and 255. Change the value by
pushing the cursor key
left or right.
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].
