• HD: Aspect Ratio Conversion Selects between the standard preset Aspect Ratio Conversions (ARC)
shown here, as well as User Defined and Follow AFD Settings.
• User Defined settings allow custom user-defined H and V aspect
ratio control.
• Follow AFD Settings sets the output aspect ratio to track with AFD
settings performed in AFD (p. 3-17).
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 on page 3-17.
• HD: User-defined aspect ratio (Horizontal) and (Vertical) controls adjust horizontal and vertical zoom
percentage. Settings less than (<) 100% provide zoom-out; settings
greater than (>) 100% provide zoom-in.
(50% to 200% range in 0.1% steps; null = 100.0)
• HD: Top line suppression Selects the number of lines suppressed at the beginning of video. In this
manner, the image is scaled proportionally to replace the top few lines
suppressed using this control. Using this control can hide unwanted
closed caption or timecode data.
(Range is 0 thru 10 lines.)
• Detail Enhancement Controls Sharpness Level, Threshold, and Noise Reduction controls (individually
described below) which can be used to tailor output video sharpness per
program material and aesthetic preferences.
Note: Detail enhancement controls apply to both SD and HD inputs.
• Sharpness Level Control Adjusts the aggressiveness of sharpening applied to MPEG video.
Optimum setting results in overall perception of increased sharpness,
while avoiding pattern noise artifacts.
(Range is 0 thru 255)
• Sharpness Threshold Control Adjusts the point at which sharpening rules become active. Data below
the threshold setting is passed unaffected.
Higher settings allow for a more subtle sharpness enhancement
(especially with content showing motion). Lower settings allow more
content in general to be acted upon by the enhancement process.
(Range is 0 thru 255)
• Noise Reduction Control Adjusts the amount of statistical low-pass filtering applied to the data.
Using this control, regular pattern noise artifacts from the sharpening
process can be reduced, resulting in subjectively smoother raster
backgrounds and detail boundaries.
(Range is 0 thru 63)
