lation of a file with LOAD)

Total vertical lines (is automatically adapted during the installation

of a file with LOAD)

Active vertical lines

Vertical start in lines

Interlaced : toggle on/off (is automatically set to its correct position

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 in the menu table. These values will be available

when starting up the EDIT procedure of an active file.

(Caution : 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" : number of pixels between the beginning of the

input signal and the start of the video information in the signal.

"Horizontal Period" : already filled in with the correct value when

active file. (see caution above).

The "Vertical Total Lines" are already filled when an active file is

selected to be edited (see caution above).

The "Active Lines" : 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 : 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, 1 frame contains 2 fields).

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.
