I've downloaded the iBOC standards (both AM and FM) and they seem to be
pretty detailed on the physical layer.  They don't mention the codec at
all, though.  It would be interesting to demod it to the point of
getting the bitstream out, for 2 reasons:  eventually there will be a
[probably non-free] software version of their codec, and there are data
portions of the stream which are not from the codec.
