Setting the Output SD Aspect Ratio

This control enables the user to define whether SD outputs should be stamped with an AFD value that
indicates a 16:9 or 4:3 output image raster. To set the aspect ratio, use the Output SD Aspect Ratio drop
down menu to select the appropriate aspect ratio.
AFD codes for SD outputs will be defined with a 4:3 output image raster AFD code.
4:3
16:9 AFD codes for SD outputs will be defined with a 16:9 output image raster AFD code.
7.9.5.

Configuring the AFD Output Enable Control

This control enables and disables the insertion of AFD packets in the outgoing video signal.
Disable AFD codes will not be inserted into the outgoing video signal.
Enable AFD codes will be inserted into the outgoing video signal.
7.9.6.

Setting the AFD Output Line

This control defines the line on which AFD packets will be inserted into the outgoing video signal when
AFD packet insertion is enabled. The user can set the output line using the AFD Output Line slider. Drag
the slider right to increase the value or move it left to decrease the value of the AFD Output line. The valid
range is from 7 to 24 with a default of line 9.

7.10. CONFIGURING THE AFD ARC CONTROLS

The AFD ARC control tab is the key control tab that enables the user to define the automatic steering of
Aspect Ratio Conversions in response to incoming AFD values. For each incoming AFD code, the user
may specify a unique scaler operating mode and a unique output AFD code. In this way, incoming AFD
codes are effectively treated as "virtual GPIs" that recall scaler specific card presets.
To properly configure the 7812DCDA2Q series cards for AFD, select an AFD code using the AFD Select
drop down menu. This corresponds to the inbound AFD value to which a specific scaler response must be
defined. In the Conversion section, select the specific ARC processing that you would like to occur every
time that specified input side AFD code is received. Further, specify the outbound AFD code in the AFD
Stamp section. Note that the AFD Stamp control is enabled only when the AFD Stamp Source is set to
User AFD Stamp. Once all settings are selected, press the APPLY button on the top of the control tab.
Perform this process for each possible incoming AFD value.
