Input: Tilt
Once a smaller window has been established by cropping the input signal, it can be moved vertically (
Tilt
,
expressed in lines) within the original image to place the desired portion of the image in view. By default, a
Center
check box beneath the Tilt scroll box forces the cropping window to be centered on the input window.
When it is checked, the necessary Tilt value will be calculated and displayed in the Tilt data window. You
cannot tilt if the cropping value is zero.
Input: Pan
Once this smaller window is established, it can be moved horizontally (
Pan
, expressed in pixels) within the
original image to place the desired portion of the image in view. A
Center
check box beneath the Pan scroll
box forces the cropping window to be centered on the input window. When checked, the necessary Pan
value will be calculated and displayed in the data window. You cannot Pan if the cropping value is zero.
Output sub-section
Output: Side Panels / Letterbox
This scrollable data entry box is used to shrink the width of the image so that the output image has blanked
areas on each side of the displayed picture, which occupy the indicated percentage of the screen width.
These areas are symmetric about the center, so a setting of 25% side panels would show a bar 12.5% of the
screen width on each side of the image. The same apply for letterbox.
Output: Position
This control allows the positioning of the output picture when side panels or letterbox are present. For side
panels, the picture can be moved totally to the left, centered or totally to the right. When letterbox is present,
the picture can be moved to the top, to the center or to the bottom of the frame. This control is not available
in Auto AFD mode or Forced AFD mode. The picture will be centered by default when an ARC Preset is
selected.
Output: Anamorphism
This control box allows the output image to be resized asymmetrically. Anamorphism is expressed in
percent, where positive values indicate an increase in width with respect to height, and negative values a
decrease in width with respect to height.
Locking
controls
Represented by padlock icons, these buttons allow the
V Crop
,
H Crop,
Anamorphism
and
Side Panels
controls to be “locked”. When a control is locked, user access to that control is disabled. Changes to
unlocked controls will not affect the data values of locked controls. There is some interactivity within the
locking function, as follows:
•
If
either
V Crop
or
H Crop
is locked,
Anamorphism
is unlocked.
•
If
either
Side Panels
or
Anamorphism
is locked, the other is unlocked, along with
V Crop
and
H Crop
.
Presets sub-section
For convenience in manual operation, several of the most common conversion situations are pre-
programmed into the XVP-1801, and can be quickly accessed. The available Presets change according to
the AFD mode and Output Format selections made using the pulldowns on the input and output screens.
The charts that follow illustrate graphically the effect of each preset on the input image.
•
Only those presets for which an output is shown will appear on the Video Output panel.
•
For example, when the input and output formats are the same, only the
Bypass
button will appear
•
In all cases, a button labeled
Custom
will appear, and will be selected whenever the parameter settings
do not correspond exactly to one of the available presets
