The first thing you should know is that cable descramblers come it two types: a single unit or a device with two units. The single unit device contains a converter and a descrambler that have been assembled jointly inside a single box. Nothing fancy so far and the unit is offering you the possibility of being easily installed and repaired. It comes in two models: one generic and one name brand model, depending on customers requests. This kind of cable descrambler has the advantage of being compatible to the systems used by the cable companies to service their networks.

On the other hand, the two-piece device comes into two separate systems - a converter and a cable descrambler which are interconnected and serve the same scope. This system has the advantage of making you pay less for every component compared to the single unit device. In case one of the units breaks down, you can repair or change it for a new one, without affecting the other component.

Cable TV companies use another type of cable descramblers, namely an addressable converter descrambler that can be effortlessly controlled by the cable company. This device is functioning on a simple scenario. The cable TV company is sending a coded message through its cable network. This coded message is reaching the device that every costumer has and the unit starts descrambling the premium or pay-per-view channels that the customer has previously paid for. This type of device is allowing the cable TV company to easily disconnect the costumers that are not paying the bill.

One thing that you should keep in mind when purchasing cable descramblers is the fact that they can not work anywhere. Cable descramblers are different from one cable network to another as cable TV companies use different scrambling systems of various brand name or model. Therefore you must purchase the exact type of cable descramblers that you cable TV company is using.

In case your cable descrambler is not working, the thing you should do is to contact your TV cable provider. It could be possible that your equipment is out-of-date and it may not meet the cable company requirements anymore.

And always stay away from bargain cable descramblers that are not being traded in specialized stores because you may end up spending you money for a good for nothing device.
