AFD
Allows assignment of AFD (Active Format Description)
codes to the SDI output video, and allows unique ARC
settings to be applied for each AFD code.
When an appropriate AFD code is received by this card,
this function can be used to apply the AFD-directed
re-aspecting, resulting in a properly scaled and cropped
image area on 4:3 displays.
