Do you remember where you read that? I'm finding it really hard
to believe. The wavelet transform, wavelet packet transform, etc.
are in use all through the sciences. There is currently alot
of wavelet software out there (see my wavelet page at
http://www.amara.com/current/wavelet.html).

There are elements in the wavelet field that are being patented. I
know that some folks at Yale are applying for a patent on the best
basis algorithm for selecting wavelet packets.

Replacing JPEG and MPEG with wavelets is a good idea. It's more
robust and handles signal degradation alot better.
