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)
• Scrambling 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 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.

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 videos 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.

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.

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.
Its preferable to use 12V, because powering it with lower 5V has a problem.
