Format Descriptor (AFD). It is
recommended to set AFD to WSS if
Aspect Ratio is WSS.

that can be sent in a MPEG video
stream that provides information
about the aspect ratio and picture
characteristics within the stream.
AFD compatible display or STB/IRD

Aspect Ratio. Aspect Ratio defines
pixel aspect ratio as encoded. AFD
is used by downstream decoding
devices to properly display pixel
aspect ratio on displays with
differing aspect ratios.
