FPV Video Scrambler Transmitter TX scrambling encryption module Receiver RX descrambling decryption module

 

Transmitter TX scrambling encryption module Receiver RX descrambling decryption module

Please don't share FPV videos with strangers, it's time to encrypt video!

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.

Troubleshooting

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" position.

2. If the video amplitude is still not enough, remove the resistor on the "2" position and short it.

FAQ

Q1: What is the added latency of these FPV Video Scrambler and Descrambler modules?

A: After adding our scrambler and descrambler modules, the delay may increase by 0.1 to 1 milliseconds.

Q2: What is MOQ for OEM for FPV Video Scrambler?

A:

1. For orders of more than 500 pieces, the PCB color and post-welding can be changed.
2. For orders of more than 5,000 pieces, the PCBA structure can be changed.
3. For orders of more than 15,000 pieces, the encryption Algorithm can be changed. It is a completely customized production and cannot be descrambled by others.
