Ernie:

While I will not comment one way or another on your speculation regarding the 
future of digital broadcasting, FCC 73.322 very specifically does not force a 
standard for FM stereo broadcasting. It does protect the 19 kHz pilot and 
mandates specific parameters IF that pilot is used. One could easily take a 
portion of a DRE bit stream and use it for L-R in conjunction with an analog 
mono L+R. Could probably be done with less than 24 kbps IF someone built a receiver.

The very same FCC takes a completely different approach to AM stereo in 73.128 
where AM stereo transmission is very specifically defined.
