Video Encryption and Decryption Module Description USB to TTL not included Feature Lightweight design Pair use (one add at the FPV transmitter, another add at the video receiver) S crambling and descrambling modules are the same. Users can define the scrambling or descrambling function in the software. Some buyers need 10 scrambling modules but only one descrambling module on the ground. 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-Encryption-Principle-for-Transmitter-TX-scrambling-encryption-module-Receiver-RX-descrambling-decryption 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. FPV Video Scrambler and Descrambler Connection Video-Encryption-Principle-for-Transmitter-TX-scrambling-encryption-module-Receiver-RX-descrambling-decryption Q6: What encryption and decryption algorithm does your video scrambler use? Is it AES128? A6: It is not encryption or decryption. It is video scrambling. Simply put, it completely scrambles the video’s queues through an algorithm. In our test video on YouTube, you can see that if we input the same encryption algorithm serial number, we can see the video. If we input a different encryption algorithm or do not use a descrambler, the video content is abnormal. Q7: How to quickly test your FPV video scrambler and descrambler without an FPV VTX VRX? A7: Please check the below two pictures. We just connected one CVBS analog camera, one scrambler module, one descrambler module, and one monitor to verify the function. how to test the analog fpv video scrambler from camera to monitor how to test the analog fpv video scrambler descrambler from camera to monitor In the picture on the left, the camera passes through the video scrambler, and the picture output to the monitor is striped or garbled, and the real picture is not clear. In the picture on the right, the camera passes through the video scrambler, and then the descrambler is added, and the picture output to the monitor is clear and real. Q8:Do you have any new designs or features of your FPV Analog Video encryptor decryptor module? A8: We will continue to improve our products based on the problems encountered and feedback from customers in FPV and actual usage scenarios. The following figure is our latest version in October 2024. https://ivcan.com/p/fpv-analog-video-scrambler-and-descrambler-module/In addition, if you have any hopes or suggestions, please let us know, and our engineers will carefully evaluate and continuously optimize. 2025 New FPV Analog Video scrambler Encryptor Decryptor descrambler module Q9: Does this module work on 1.2-1.3ghz Analog frequency? A9: Yes. Our FPV analog video scrambling module performs scrambling and descrambling on the video signal. It has nothing to do with the FPV VTX frequency. So it can work with any transmitter frequency. Q10: Can you tell me the minimum and maximum voltage supply need? A10: 5-12V. The minimum voltage required is 5V.It’s preferable to use 12V, because powering it with lower 5V has a problem. Software Show more
