Patty, they have to letterbox any HD programs that they rebroadcast, unless they crop the picture, because their SD programs are all in 4:3 AR. I don't know why they don't use 16:9 AR 480p for down-converted HD programming, which is certainly a legal ATSC format, instead of sticking with 4:3 AR all the time. Perhaps it has to do with lowest-common-denominator DTV compatibility.

I suffered through KQED.Inc. experiments switching formats on the fly prior to the Analog NTSC Shutdown. They tried if I remember correctly on both RF 30 and RF 50.

It did not work at all IMHO and they learned their lesson quite well as when they made the switch in 2008 they have never tried again.

Now if you are talking about what Cozi is sending, the answer is that the amount of 16:9 programming is small compared with the amount of 4:3 programming still.

Spoiler!
