Providing content that allows subscribers to select program packages they are interested in instead of providing larger amount of channels has become a reality. Customers require choice and are ready to pay for the high-quality content.
To achieve the requirement where every customer has to contact the service provider and sign a contract for receiving additional content, the signal must be obfuscated in a way that only subscribed users can receive it. Devices that encode signals this way, are scramblers and devices that are located at the customers’ premises are descramblers.
TotalCrypt Management Software is the software that runs on a designated server and allows multiple users with their credentials to manage what content can each of the end-users receive. It works in a combination with TotalCrypt Scrambler which is a hardware device that does the scrambling.
Pay TV services are becoming even more popular with the growth of High Definition Channels due to their special licensing scheme.

System runs on a dedicated server with replicated database. This allows multiple users to have their accounts and sub-accounts with their own assigned stock. It allows very easy-to-use channel, packet (groups of channels) and user management. Different data exports are also available to use the data for billing purposes.

The TotalCrypt scrambler, developed by CableWorld solves the descrambling function at the receiving side by using the standard Common Interface (CI), thus any set-top box or later digital TV set equipped with CI can be used for reception.
The gist of the TotalCrypt system is converting the set-top boxes or digital TV sets into addressable descramblers by inserting TotalCrypt descrambler modules in their CI slots. Each TotalCrypt descrambler module is equipped with an individual address, and the scrambler in the headend controls the descrambler modules by special data embedded in the transport stream. The descrambler modules receive from the transport stream both the descrambling algorithms and the signals authorizing the subscribed programs, thus both enabling and disabling the reception can be controlled in an easy way.
The TotalCrypt Pay TV scrambler is used in the headend for scrambling the ASI signal going to the
QAM modulator. The scrambler is not integrated into the system, thus it can be included or excluded at any time. The scrambler is not bound to CableWorld device environment; it can be used in the headend of any manufacturer. The scrambler does not change the data rate; the space for embedding the control data has to be provided in form of null packets. The quantity of the necessary control data depends on the number of subscribers and the required recovery time of the set-top boxes, and it can be programmed in a wide range.
The TotalCrypt descrambler module is DVB and CI compatible however the scrambling is made not according to the standard but in a special system developed by CableWorld, that makes hacking even more difficult. The descrambler modules receive continuous individual control by their identification numbers from the transport stream. The scrambling system provides scrambling up to 64 elementary streams within the transport stream and their individual authorizations.
