If it doesn't descramble any more, perhaps the cable company broadcast control signals that the descrambler is designed to listen for, and it will shut off when it receives the right code. >How in the hell can they do this? I could understand on the new two-way >systems, but on the old A/B one-way systems, how could they "zap" a system? basically, certain descramblers are built to stop working if they get told the secret-magic-auto-destruct sequence (you know, same way Capt. Picard can lock out the helm with the right code words :-) I don't _know_ of any that actually destroy themselves, or at least permanently damage themselves; but they could easily do it by making the descrambler turn on a voltage that erases all its microcode, or blow a fuse... > If they can do this, how could one defeat it? build/hack a descrambler to ignore or bypass it. > >****************************************************************************** >Rick Eames My Opinions Are My Own (not >Apple's) >athos@apple.com >Don't blame me, I didn't vote for Boxer. >****************************************************************************** -- __________________________________________________________________________ John Paul Morrison | University of British Columbia, Canada | Electrical Engineering | .sig file without a cause jmorriso@ee.ubc.ca VE7JPM | ________________________________________|_________________________________
