Product Description The data controller located at the front end of
the system generates digital signal via its microprocessor andsend
scrambling order to scrambler. The end user descrambler descrambles
after receiving proper descrambling data and fee-controlling data.
The system is succeed in signal-descrambling and image restoration,
and it is widely used in the full channel scrambling as well as
partial channel scrambling of CATV.
Only one data controller is needed In front of this system, but
scrambler can be fixed in many proper points according to needs.
This system also can solve the PTV billing problem effectively.
