Aperture Correction
We provide a horizontal aperture corrector for the converted outputs which permits the
sharpening or softening of the SDTV outputs (a slight roll off in high frequency is a normal
part of the down conversion filtering process). The checkbox can be used to switch
aperture ON and OFF. (ON= Default). When set to ON a small preset amount of
correction is applied to produce a flat frequency response on the outputs. When set to
OFF all Aperture correction is removed.
The amount of aperture correction is adjustable (from the factory preset)
range + 30 to -80. Adjustments in the positive direction will sharpen the image and the
negative direction will soften the image.
SDI output routing
There are two small radio buttons which can be used to change the SDI digital outputs.
One selection takes the signal before the down converter and will provide two re-clocked
outputs of the incoming SDI signal. The other selection (default) provides two converted
digital outputs.
Output Standard
The output standard is indicated in green for the analog and digital outputs.
Note
The down converter will automatically select the correct output standard
depending on the connected input standard. For example if a 50Hz input signal is
detected then a 625 PAL output will be provided. Likewise if a 59.94Hz or 60Hz
input is detected then a NTSC 59.94Hz output will be provided.

conversion and proc functions
