The AFD flag is implemented differently in HD and SD:

In HD, the AFD flag (SMPTE 2016) is sent as an ancillary packet, normally found on line 11 in the vertical ancillary
space.

In SD, the AFD flag is sent as a Video Line Index (VLI) signal (RP 186), as a Wide Screen Signalling (WSS) signal
(ITU-R BT.1119-2) for 625 only, or as an AFD packet (SMPTE 2016).
Note that in HD only AFD can be extracted. Switching from SD and HD will automatically extract the
configured aspect ratio source in SD and AFD in HD.
Mode
Follow
Metadata: Select the code extracted from the input signal and process (scale) the video accordingly. If there
is no aspect ratio code Forced mode code will be used.
Forced: Select the FORCED HD selection (e.g.: 16:9_8) when an HD signal is present or the FORCED SD
selection (e.g.: 4:3_8) to process (scale) the video accordingly.
Note that there is a 1 frame response time when there is an aspect code change if Follow Metadata is
selected.
Forced HD
Select the AFD code that will be forced for an HD input video signals when the scaler is set to anything but Off.
