VEM Video Encryption Equipment
1：Principle of video encryption：
After collect CVBS videos and perform AD (analog-to-digital) conversion. The converted digital signal is encrypted through FPGA, and the video image is reprocessed. Then perform DA(digital-to-analog) conversion to generate a standar CVBS and output to the transmitter as shown in Figure (1)
Principle diagram as below:
