Setting the Aspect Ratio Converter

The Aspect Ratio control sets the aspect ratio control that will be performed during the up/down/cross
conversion process. Many of the standard aspect ratio conversions are listed as pre-defined options
that may be selected. In addition to this, custom aspect ratio conversions can be defined using the
USER mode of operation. Once USER is selected, Input H Start, Input H Stop, Input V Start, Input
V Stop, Output H Start, Output H Stop, Output V Start, Output V Stop controls are used for this
purpose. The active region of the input raster is defined by the Input H Start, Input H Stop, Input V
Start, Input V Stop. The region defined by those controls is scaled to the output raster as defined by
the Output H Start, Output H Stop, Output V Start, Output V Stop. Colored image side panels can
be utilized to fill regions of the output raster that are outside the region defined by the output image
raster controls.

DESCRIPTION
Converts the full input raster to full
output raster. If the input and output
aspect ratios are not equivalent there
will be aspect distortion.
Converts the region of the active input
raster as defined by the Input H Start,
Input H Stop, Input V Start, Input V
Stop controls to the output raster as
defined by the Output H Start, Output
H Stop, Output V Start, Output V
Stop.
These settings convert the input picture
to 16:9 top and bottom cuts.
These settings squeeze common 16:9,
14:9 and 13:9 input aspect ratios to 4:3
side paneled images on a 16:9 aspect
raster.
