On the "ashamed to be an engineer" aspect--look at the ARDG (Analog

be plenty of engineers who actually think this can be made to work,
for suitable definitions of "work".
Ooops, that should be http://www.cptwg.org
So, what if they actually get this stuff through, and all
analog-video-to-digital devices have a
"detect watermark and drop" mandated?
It seems to me, that given ifft(fft(x)) == x, then one could produce a
special form of spectral inversion
device by taking the bins of a suitable-resolution FFT, re-ordering
them to taste, then computing an
IFFT on the result. The "video-to-digital" converter would never see
its watermark, then you just
re-arrange the spectra back to the way it should be after the
"watermark detect" phase. But maybe I'm
all wet, as it were.
