發射器TX加擾加密糢塊接收器RX解擾解密糢塊

Please don’t share FPV videos with stranger, it’s time to encrypt video！

功能

• Lightweight design
• Pair use (one add at the FPV transmitter, another add at the video receiver)

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.

Parameter settings

1: Open the configuration software, find the corresponding serial port number, select and open the serial port and click “read” to read the current device parameters.

2: 選擇 “Scramble” 或者 “Descramble” mode and enter the required scramble or descramble sequence.

3: Press “Write” to write data.

故障排除

Special case description: Due to the differences in the video amplitudes of cameras, 視頻發射器, 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” 位置.

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