• Alignment Offset Selector
Based on alignment selection selected above, offsets A-frame by amount
selected.
• Low-Latency PSF to Interlaced Control
Allows PsF to Interlaced conversions bypassing Scaler ARC and Pan
controls to enhance processing latency performance over that available
in normal mode.
• Disabled: This is “normal” setting that locks out the low-latency
processing function. Normal scaler processing latency (along with
full ARC and pan control) is available with this setting.
• Enabled (Use Both Fields): This setting provides a highest-quality
low-latency setting, and can be expected to provide an approximate
latency of 12 msec for North American frame rates.
• Enabled (Use Top Field): This setting provides the lowest
available latency with a slight reduction of motion smoothness due
to alignment not waiting for both fields. This setting can be expected
to provide an approximate latency of 6 msec for North American
frame rates.
Note: When either low latency mode is enabled, image ARC scaling and/
or panning is locked out.
• Standard Quick Set Aspect Ratio
Conversion Selectors
Selects between the standard preset Aspect Ratio Conversions (ARC)
shown below.
Note: This function is intended for aspect ratio adjustment of a particular
signal without AFD considerations.
- If ARC is being used on a case-by-case basis for a particular
signal, it is easier to use the Scaler ARC tools described here.
- If AFD is to be used to set and apply a standard AFD code label
for ARC, use Follow AFD Settings. Do not perform ARC here;
instead, perform ARC as described in the AFD function
description per AFD/WSS/VI Code Insertion Controls (p. 3-33).
• User-defined Aspect Ratio Controls
Aspect Ratio Horizontal and Aspect Ratio Vertical controls adjust
horizontal and vertical zoom percentage. Settings less than (<) 100%
provide zoom-out; settings greater than (>) 100% provide zoom-in.
(50% to 150% range in 0.1% steps; null = 100.0)

Buttons allow standard ARC presets
to be applied to output video. For any
setting, using the Horizontal or
Vertical controls allow user custom
settings.
Pressing any of the preset buttons
restores the ARC to the selected
setting and overrides any previous
custom settings.
