- I am sure there are a few different ways that cable companies do this.
- But in recent meetings with major brand converter sales reps, they told
- me that most modern addressable converters have an additional register that
- triggers when it receives a special code on an illegaly authorized box.
- Scrambled channels are then switched to a channel carrying a message to
- call the cable company to report service problem so and so. Smart thieves
- are forced to throw away the box. Incredibably, many absent-minded thieves
- actually call their cable companies.
