7.7.1.2. Loss of AFD Timeout
This control enables the user to configure the action that the converter will take when incoming AFD
signals are lost or not present. When incoming AFD signals are lost or not present the module can revert
to a default ARC/Scaler setting or continue to use the last valid AFD received to steer conversions. The
user can set this action by selecting one of the options from the slider.
0 Frames (Use
When incoming AFD values are absent, ARC processing will revert to default
ARC processing as defined in the Scaler control tab.
Infinite
When incoming AFD values are absent, ARC processing will use the last valid
AFD code received to automatically steer ARC processing.
1 – 300 frames
When incoming AFD values are absent, ARC processing will use the last valid
AFD code for x amount of frames. If a valid AFD signal does not return for the
selected amount of frames the AFD will revert to default.
7.7.1.3. AFD Stamp Source
This control enables the user to set the source for output AFD stamping. The user may configure the card
to use the AFD value automatically generated by the scaler and its setting or to stamp a user defined AFD
value.
Use Scaler
AFD values stamped on the outbound video signal will be those AFD values
automatically generated by the scaler and its settings. The AFD Stamp control will
be disabled in the Scaler control tab and the AFD ARC control tab since AFD
values will automatically be generated by the scaler.
User AFD
Stamp
AFD values stamping on the outbound video signal will be the user specified AFD
value.
7.7.1.4. AFD 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.
4:3
AFD codes for SD outputs will be defined with a 4:3 output image raster AFD code.
16:9
AFD codes for SD outputs will be defined with a 16:9 output image raster AFD code.
