Addressable Pay TV System Solution , Scrambling System Solution;

The scrambling technology is unique and advanced: the system adopts more group of numbers scrambling technology is unique and advanced: the system adopts more group of numbers combination technology basing on radio frequency in the front, and can scramble 45 to 750MHz at the same time. The terminal adopt group de-scrambling technology, and communication adopt computer addressable authorization way. Integrated with digital technology, analog technology, radio frequency and communication technology, the scrambling system makes it be the most advanced one among similar products at present. Moreover, scrambling and coding adopt digital/ analog combination technology, and greatly improve reliability and security of system.

       The image revivification is high: Because this  kind of scrambling is done only on the radio frequency, and de-scrambling is done directly on radio frequency, not including modulation and demodulation (don't touch the video structure), the quality for de-scrambled image is high. Any scrambling modes set about from video without exception on the market at present: the synchronous head compressing, row cutting, polarity reversing etc. will certainly cause influence on image video quality and S/N.

       High secrecy, security and reliability for system: Because of adopting more groups of numbers scrambling modes and scrambling time after time, possibility that the translator obtain the de-scrambled data will be stopped fundamentally in this way. Even if parts of them are decoded, the front only needs to change scrambling program, and the translator will be unable to de-scramble. Therefore, secrecy and security for system is extremely high.

      The management for System is scientific: The system uses the computer intelligent administrative software, as well as WINDOWS interface. It has authorized charge, inquiry, systematic maintenance and so on for front users; and it is easy to operate and use.

       Low costs: with Radio frequency scrambling, the front devices are less (there needs a computer, a addressing machine, a scrambling machine and a charge administrative software respectively). Cost for user de-scrambling device is low, which not only reduce user's cost of investment, but also carry on scientific management to the network.
