Not and still work reliably.

Actually, my experience is that that is not true.  I suspect because
the television studios know that this is a remarkably decent method of
commercial detection.  Indeed, I expect one day that there will be no
black frames between commercial segments and the program.

Or rather, broadcast television will be encrypted (there are already
moves afoot in the US by the television broadcasting interests to have
free-to-air HDTV encrypted) and you will only be able to decrypt it
with approved devices, much like the current state of trying to watch
a DVD.

Devices that are approved to watch broadcast television or record it
will not be able to skip commercials, and any device that is produced
that is not approved will be a DMCA violation and the inventor will be
thrown in jail.

And don't you Euros think the DMCA does not apply to you.  There is a
DMCA coming to a living room near you.  From what I can understand,
similar DMCA-like laws are being floated in the EC.

Like I said, it will not be reliable.  It is not uncommon for there to
only be 2-5 frames black.

Not really.  Not mis-detections but non-detections.
