VDM Video Decryption Equipment
1：Principle of video decryption：
We perform AD (analog-to-digital) conversion with the CVBS video signal received by the receiver, decrypt the converted digital signal through FPGA, reprocess the video image, and then output it for DA (analog-to-digital) conversion to convert it into standard CVBS and output it to the display as shown in Figure (1)
Principle diagram as below:
