7.4.2.2. Setting User Defined Aspect Ratios

There are four controls for each input video standard that set the portion of the input picture that will be
converted. These controls do not have any effect when the pre-defined aspect ratios are used.
Changes to the Input H/V and Output H/V aspect ratio parameters will cause the
video output to be interrupted momentarily. The internal timing is automatically
adjusted to achieve the desired phase with respect to the reference.

There are four controls for each output video standard that define the size of the output image and where
to place the resulting image on the destination frame.

This parameter allows users to use menu settings from the Aspect
Ratio Mode menu items as a starting point to create user-defined
conversion settings.
Choose yes to load Aspect ratio mode settings to the Input and output
start and stop menu items.
The Input H start and Input H stop define where the first and last pixels
of the input image are within the source frame.
Source frame pixel of left side of input image (first pixel)
Source frame pixel of right side of input image (last pixel)
The Input V start and Input V stop define where the first and last lines of
the input image are within the source frame.
Source frame line of top of input image (first line)
Source frame line of bottom of input image (last line)
The Output H start and Output H stop define where the first and last
pixels of the output image are within the destination frame.
Destination frame pixel of left side of output image (first pixel)
Destination frame pixel of right side of output image (last pixel)
The Output V start and Output V stop define where the first and last
lines of the output image are within the destination frame.
Destination frame line of top of output image (first line)
Destination frame line of bottom of output image (last line)
