The invention discloses a safe wiring method for a PCB board to prevent a signal from being stolen. The PCB board comprises an insulating substrate. A chip, a data bus, an address bus, a testing point, through holes, a socket and the like are arranged on the substrate. The chip connected with the data bus and the address bus adopts BGA encapsulation. The data bus and the address bus are provided with less through holes as possible, and the through holes are hidden under a BGA encapsulating body, and are away from pads connected therewith. The data bus and the address bus are provided with less matched resistors as possible. If a resistor array is needed, discrete resistors are used instead of the resistor array, and the resistors are numbered randomly and are scattered. No socket or testing point is connected with the data bus and the address bus. The safe wiring method for the PCB board can effectively prevent a hacker from stealing signals, greatly improves the safety of signal transmission ...

The invention discloses a method for protecting a satellite television LNB from short circuit. The method comprises the steps of: firstly starting H/V control voltage output in the process of detecting the LNB short circuit, wherein the H presents horizontal polarization and the V presents vertical polarization, waiting for a period of time till the output voltage is stable, reading a short circuit detection level value immediately, keeping the started H/V control voltage output and then turning back to the beginning point and re-detecting the short circuit if the LNB short circuit is removed, or immediately closing the H/V control voltage output while displaying an OSD prompt message showing LNB short circuit on a video output if the LNB is short-circuited, and then turning back to the beginning point for detecting the short circuit after delaying a period of time. The technical solution of the invention is that the system can detect the short circuit in 100 milliseconds and cut off the ...
