Video Encryption Principle
We collect CVBS video and perform AD (analog-to-digital) conversion, encrypt the converted digital signal through FPGA, reprocess the video image, and then output it for DA (digital-to-analog) conversion, and convert it into a standard CVBS output to the transmitter.

Video Decryption Principle
We convert the CVBS video signal received by the receiver into AD (analog-to-digital), decrypt the converted digital signal through FPGA, reprocess the video image, and then output it for DA (digital-to-analog) conversion, and convert it into a standard CVBS output to the display.
Parameter settings

Special case description: Due to the differences in the video amplitudes of cameras, video transmitters, and video receivers produced by different manufacturers, the video brightness may not be enough during use. If this happens, please follow the steps below to modify the module.
1. First remove the resistor on the “1” nafasi.
