• H Zoom and V Zoom Controls Individual H Zoom and V Zoom controls for each of the 12 AFD code
choices for both 4:3 and 16:9 coded input frames described above allow
adjustment of horizontal and vertical zoom percentage for each AFD
code.
(50% to 200% range in 0.1% steps)
Note: To apply H and V settings for a given AFD code using this card,
Scaler Aspect Ratio Conversion must be set to Follow AFD
Settings.
Note: Default zoom percentages use the following rules:
• The default zoom percentages displayed when this function is
accessed are the default percentages corresponding to the
respective AFD standard ratio definitions (for example, default
horizontal and vertical zoom percentages for 4:3 ratios are
correspondingly 133% and 100%, yielding a 4:3 aspect ratio). In
these cases, the null values for this definition are the default values
shown.
• In cases where a different aspect ratio is to be used for a given
received aspect ratio, the default ratio displayed is the null value
that results (assuming no H or V zoom modification). For example,
for a 16:9 signal and settings set for a 1111 (15) AFD code (“16:9
with 4:3 protected image”), the respective displayed default H and V
zoom settings of 100% and 75% protect the Protected Image Area.
• AFD Output Code Twelve drop-down lists that allow assignment of AFD codes to the 12
individual H Zoom and V Zoom tools described above.
Note: • The default AFD codes displayed when this function is accessed
show the SMPTE AFD code most closely reflecting the aspect
ratio when the corresponding default settings are applied.
• An AFD Output Code setting has no effect on aspect on ARC
performed by this card; it merely applies a selected AFD code to
the output video.

In this example, if a “0011” AFD code is received, the entered
H Zoom and V Zoom values corresponding to AFD code 0011
are applied to the image (133.0% and 100.0%, respectively, in
this example). The H Zoom and V Zoom values for any AFD code
can be changed as desired. When the card Scaler Aspect Ratio
Conversion is set to Follow AFD Settings, the H and V zoom
values set here are applied to the output video. In this example, with the AFD Output Code
drop-down set to 1000, if a 0011 code is received
on the input, an AFD code of 1000 is ouputted by
the card. (Note that the assigned output code has
no effect on ARC performed within this card.)
