9903-UDX-ADDA Function Menu List and Descriptions
(continued)
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).
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)
H Pan control shifts horizontal center of image left (negative settings) or
right (positive settings)
(-74% to 74% range in 0.1% steps; null = 0.0)
-74 0
V Pan control shifts vertical center of image down (negative settings) or
up (positive settings)
(-74% to 74% range in 0.1% steps; null = 0.0)
Adjusts the aggressiveness of sharpening or filtering applied to output
video. Optimum setting results in overall perception of increased
sharpness, while avoiding pattern noise artefacts.
(Range is 0.50 thru 1.50 in 0.01 steps; null = 1.00)
