I asked the same question when I first started looking into this but
there does not seem to be anything available.
It is part of the MPEG headers rather than the DVB data. The AFD tag is
similar to the one containing the normal MPEG 16:9/4:3 aspect
indication. I found the header parsing code for the aspect ratio in the
existing vdr-dxr3 driver and it was fairly easy to add another case to
decode the AFD header as well.
