User Aspect Ratio Setting

There are four controls that set the portion of the input picture that will be used for conversion. These
controls are Input H Start, Input H Stop, Input V Start and Input V Stop. Effectively, these controls are
used to define input image cropping.
There are four controls that set the output image size. These controls are Output H Start, Output H Stop,
Output V Start and Output V Stop. Effectively, these controls are used to define the amount of scaling that
the module will perform. They also define the position of the active video within the total output image
raster.
Move the Input H Start/Input H Stop/Input V Start/Input V Stop and Output H Start/Output H Stop/Output V
Start/Output V Stop sliders to the left to decrease their values and move the sliders to the right to increase
their values.
As these parameters are adjusted, a real time pictorial representation of the conversion being manually
defined will be displayed as shown in Figure 7-31.
