Anti-piracy method for group scrambling and descrambling charging system

Abstract

The invention relates to a group adding descrambling charging system anti-piracy method. An anti-piracy program is disposed in group adding descrambling charging management system software. The method is characterized in that whole-network no scrambling periods and whole-network scrambling periods are set; a whole-network scrambling program or a whole-network no scrambling program is synchronously executed onto front-ends and users at different periods; during the whole-network no scrambling, authorized users can watch programs normally without starting the descrambling program and while users of piracy cannot watch programs normally. The advantages of the group adding descrambling charging system anti-piracy method are that the descrambling program of a descrambler does not need to be modified; the scrambling and the descrambling for the front-ends and the users can be performed at the same time; and only the authorized users and the front-ends can receive scrambling and descrambling synchronously while the watching of programs being not affected.

Description

technical field [0001] The invention relates to an anti-piracy method for a group scrambling and descrambling charging system, which belongs to the technical field of scrambling and descrambling of a television transmission system. Background technique [0002] In recent years, in the group scrambling and descrambling cable TV system, more and more unauthorized set-top boxes are illegally installed, and they can watch all TV programs without paying the viewing fee. The set-top box does not require front-end authorization, and executes the descrambling program under any circumstances. The general group scrambling and descrambling system cannot control its use, which brings huge economic losses to network operators. [0003] Chinese patent 03118152.X discloses an anti-deciphering, anti-stealing, anti-stealing broadcast addressable TV plus and descrambling charging management system. The scrambling and descrambling fee management system includes the scrambling part and the des...

AI Technical Summary

Problems solved by technology

In the above technical solution, the descrambling program for group adding and descrambling is written in the set-top box. To replace the descrambling program so that the unauthorized set-top box cannot work, all the set-top boxes must be returned to the network company to modify the program, and the workload is very heavy.
