Set-top boxes are now the most commonly used type of household appliances. Previous televisions were able to watch as long as they were installed with wires, but now basically two set-top boxes are minimal for each household. Today, Xiao Bian will talk with you about the latest cracking methods for cable and digital set-top boxes. 
Cable set-top box crack
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. Use an off-or gate circuit or 555 circuit to create an open multi-vibrator, whose resonant frequency can cover the entire frequency band of cable TV. (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. Use a high-frequency transistor such as the 9018 as a high-frequency transmit circuit, and use the RF output to transmit again. As long as the small transmit power, 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.
Digital set top box crack
1. Make an open multi-vibrator with a non-AND gate circuit or 555 circuit, place it next to the set top box, and let it receive the signal from the vibrator, and then use the splitter to branch out from the output of the set top box. TV can be.
2. There is a branching device that can branch the signal received by the television to another station by first placing the set-top box near one of the television sets so that it can receive the signal and then branching the signal to the other TV using the branching device. . This method has the drawback that other televisions can only receive 5 channels near the first TV channel, which is very limited.
3, the use of high-frequency emission circuit RF output re-signal, as long as the set-top box can receive it.
4. Remove the outer shielded cable from the coaxial video cable, and connect it to the corresponding input or output. The middle cable stays about one meter long. Wind the cable around the set-top box and let the set-top box receive the signal from the leak.
