11.5.7 Scaler Config – Output Config
The Output Config functions define which of the supported aspect signaling standards defines
the input of the ARC.
11.5.7.1
Conversion Scaling
Conversion Scaling enables you to set fixed ARC output aspects.
•
Fit to Height:
Scales the image to fit the height of the screen while maintaining the
aspect ratio.
•
Fit to Width:
Scales the image to fit the width of the screen while maintaining the
aspect ratio.
•
14:9:
Can scale either a 4:3 image for viewing on a 16:9 screen, or a 16:9 image for
viewing on a 4:3 screen. This is a compromise in order to maintain the aspect ratio of
the image, but will crop some of the image in the process (top and bottom when
viewing 16:9 and left and right when viewing 4:3).
See see section 11.5.8 for a list of possible ARC conversions using input signaling and a
combination of SD Output Format and Conversion Scaling controls.
11.5.7.2
SD Output Format
When the output video is SD, this control enables you to set fixed output aspects for the ARC.
•
Normal:
Default aspect ratio.
•
Anamorphic:
Horizontally squeezes a widescreen image to fit a standard 4:3 aspect
ratio.
11.5.8 Input Signaling ARC Conversions
It is possible to manually fix the output aspect of the ARC when using input signaling. The
input to the ARC is then defined by the dynamic input signaling.
The following sections show the ARC conversions possible using input signaling and a
combination of SD Output Format and Conversion Scaling controls. For each of the
conversions there are four columns of images. The first column shows the source image in
various formats, with each format described in the accompanying input signal. The next three
columns show the output image format when the Fit to Width, 14:9, or Fit to Height
Conversion Scaling controls are selected.
