The wireless communication module 22 is used for sending and receiving signals of the set-top box protection system 2. The mobile communication module 31 is used for sending and receiving signals of the operator mobile terminal 3.
As shown in fig. 2, the hardware encoding module 26 stores the production code of the set-top box internal hardware. The instruction intercepting module 23 intercepts signals input into the set-top box from the outside and prevents the main control program 4 from interacting with the outside, and the instruction intercepting module 23 outputs request signals input into the set-top box. The start request module 24 receives the request signal output by the instruction interception module 23 and calls the production code stored by the hardware code module 26, and the start request module 24 outputs the request signal and the hardware code.
