While I don't know exactly what Al meant with "good information"
exactly, here's maybe a way to interpret it: The information that is
removed with lossy compression is in the best case exactly that
information that is redundant with respect to human perception. It would
be "good" in the sense that this redundant information would be a great
place to hide watermarking. With a "perfect" lossy compression scheme,
there's no bandwidth left to alter the signal without the human
perception noticing.. So any watermark would be audible.
