Vertical bandwidth
When down converting the vertical bandwidth can be optimised for a given application
by selecting the most appropriate vertical bandwidth filtering. There are four filters to
select from, ranging from the highest (sharpest) to the lowest (softest). Check the
radio button to select the chosen filter characteristics.
Aspect ratio control
There are four tabs, each associated with one of the four fixed aspect ratios -
Anamorphic, 16:9 Letterbox, 14:9 Letterbox and Centre cut. Each of these four tabs
when active allows the picture size to be adjusted and cropped, and the position on
the screen varied.
Aspect ratio status information is given to the right of each set of controls. An
illuminated LED indicates which aspect ratio selection is active, green being the
opened tab and yellow a tab other than the open one. If a status LED is showing
yellow, pressing Select will cause the open tab to become the selected aspect ratio.
Should the disable LED be illuminated red, aspect ratio conversion is prohibited.
Pressing the Cal button will return all slider control to their default value.
