I agree, Mark. I was going to make a posting similar to John's last night,
but I realized that I was engaged in legacy thinking; afd is just as useful
with a 4:3 set as a 16:9 one.
AFD permits, as Adam alluded to, the broadcaster to dynamically define the
active video frame, and it's not just usable for signaling 16:9 or 4:3, but
1:2.21 and any other as well, and gives the receiver enough information to
figure out how to render the largest possible image based on the screen size
of the receiver.
The lack of it being mandatory -- to this point, anyway -- is another one of
those 'mini-failures' on the road to digital broadcasting, along with the
dialnorm dropped ball, the effective banning of multiple audio decoders (in
otherwords, seriously limiting AC-3 flexibility), lipsync and [add your
own.]
As for the coupon-box lack of afd, what do you expect of 'government
cheese?'

And if a broadcaster decides to use AFD to intermix 16:9 and 4:3
material, what does a non-AFD box deliver?
TTFN,
