Correct value
What is already available during start up?
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.
Do not adjust these settings on an active file, they are used to identify the input source file.
How to find the correct values for the item in the Edit file menu?
Horizontal Total Pixels
If the value for "Horizontal Total Pixels" is wrong, sampling mistakes (small vertical bars with noisy
and unsharp data 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.
Active Pixels
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.
Vertical Total Lines
already filled when an active file is selected to be edited
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.
AMDS INTL [ON/OFF]
Still [On/Off]
•
On interlaced files switching the STILL option ’ON’ or ’OFF’ turns the de-interlacing on or off.
•
For video files the default setting will be ’ON’. This increases the perceived image quality by
reducing the flicker (caused by the interlacing) and improves the interpolation (better sharpness
with less artefacts). However when the image data is moving very fast, in other words when
there’s almost no correlation between succeeding field data in a certain area, one might prefer to
put the still mode ’OFF’ to avoid motion artefacts.
•
In interlaced data files, the option for that type of files would be set to ’OFF’ by default. In that
case the user might still prefer to put the still option ’ON’ when applying test patterns.
•
On non interlaced files it turns the so called despeckle mode on or off. The default setting for non
interlaced files is ’OFF’. This option is useful to reduce many kinds of variable disturbances,
even clearly visible spikes in the video data signal or unstable phase situations when using high
frequency pixel clocks or bad sources. This is done using a statistical filter which eliminates
disturbances that only occur in one field. The still mode reduces (potential) image disturbances
but can introduce motion artefacts.
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 remeasures
the above indicated items.
