With the progress of the times, televisions are constantly evolving. But a new problem has emerged: the average TV set-top box has to pay a high price. However, many rural families are reluctant to buy a TV set-top box, so they need to crack the TV set-top box. But will you break it? Let's learn together with Xiaobian.
Set-top box cracking works
The encrypted signal is input through the input terminal, and the interference signal (scrambling encryption) is cancelled by its internal circuitry, and the normal signal is output through the output terminal. There is an external condition for whether the decryption circuit works or not, that is, the signal fed back by the high frequency head of the television.
If this signal is not fed back to the set-top box, its descrambling circuit does not work and the undecrypted signal is output as it is, and thus cannot be viewed normally. The decrypted frequency band is divided into several segments for decryption. If the television is receiving 3 channels, the high frequency head of the TV will feedback the resonant frequency of the 3 channel to the set top box, and the set top box will output the normal signals of 1 to 5 channels, and so on.
First, the digital television set-top box crack ideas TV station to change the incoming television signal input digital encryption equipment, the television signal through the algorithm encryption output terminal after the decryption of the set-top box output of ordinary RF signals, and finally delivered to the terminal receiving equipment, Bring the picture out of the TV.
However, the television can only receive ordinary radio frequency signals, so it can only be decrypted and then input into the television. There are many kinds of cable television encryption methods, and here is the use of "scramble method." It is very difficult to succeed in illegally accessing the TV signal when encrypting and decrypting this line. However, the decrypted signal of the set top box can receive any television signal and play the picture through the television.
Second, digital TV set-top box crack method
Solution 1: Set up the set-top box on the top of one of the televisions (TV 1) so that it can be viewed normally, and then use the splitter to branch off the signal from the output to another TV. One disadvantage of this approach is that the other TV set can only receive 5 channels near the channel that TV 1 receives.
Solution 2: Use an off-or gate circuit or a 555 circuit to create an open multi-vibrator, whose resonant frequency can cover the entire frequency band of cable TV. Place this multivibrator next to the set-top box. Let the set-top box receive the signal from the vibrator, and then use the splitter to branch out from the output of the set-top box to multiple televisions, so that all televisions can receive channel signals.
Solution 3: Use a high-frequency transistor such as the 9018 as a high-frequency transmitter circuit, use the RF output to re-emit, as long as the small transmit power, so that the set-top box can receive it. Or use the coaxial video line branch access input or output, and then remove the outer shielded line, leaving only the middle of the line length of about 1 meter, the line around the set-top box, so that the signal leaked out to the set-top box receiver. Thus, the digital television set-top box signal is cracked.
Cable set-top box cracking method
1. Put the set-top box near the high-frequency head of one of the TVs (TV 1) so that it can be viewed normally, and then use the splitter to branch off the signal from the output to the other TV. One disadvantage of this approach is that the other TV set can only receive 5 channels near the channel that TV 1 receives.
2. Create an open multi-vibrator with a non-AND gate circuit or 555 circuit, as long as the resonant frequency can cover the entire frequency band of cable television. (Production costs about 6 yuan) Place this vibrator next to the set-top box. Let the set-top box receive the signal from the vibrator, and then use the splitter to branch out from the output of the set-top box to multiple TV sets. In this way, all TV sets can receive signals from all channels.
3, with a high-frequency transistor such as 9018 to do a high-frequency transmission circuit, use the RF output to launch again, as long as a small transmit power, so that the set-top box can receive it. Or use the coaxial video line branch access input or output, remove the outer shield, leaving only the middle of the line length of about 1 meter, this line around the set-top box. Let the leaked signal sense the set-top box to receive.
