How does a digital cable descrambler/filter work?
There is NO SUCH THING AS A DIGITAL CABLE DESCRAMBLER. There are TONS of ads for these “digital descramblers”. They are NOTHING MORE THAN A HIGH PASS FILTER! They do not work! What these things do is prevent a cable modem or digital cable box from talking back to the cable company, therefore it will not report Pay-Per-View purchases back to the cable company. Here’s the catch though: The cable company is constantly polling the digital box for signal levels, purchases, and troubleshooting information. If it doesn’t hear back from the box, they will flag your account and roll a service call truck on it. Since there is no way for you to clear the PPV purchases out of the boxes’ memory, you’re going to end up getting charged someday anyway. Don’t waste your money.
