Kedu ka FPV analog video encryption-decryption modul na transmitter-nnata iji chebe nzuzo

Transmitter TX scrambling encryption module Receiver RX descrambling decryption module is our FPV video encryption and decryption module.

I will show you how it work at the above video.

First let us see our encryption module, it has an video input and 12 volt input. At the another side, there is an video out. One video cable is connecting the output to our 1.2Ghz analog transmitter. The TTL serial port is connecting to the computer.

This is our 1.2Ghz FPV video receiver, It receives video wireless from the video transmitter. It’s video is connecting our decryption module. This is the 12 volt power input, the video output to our monitor after decryption.

Now the scrambled video on the monitor is not seen well. Becaues our encryption key is 600 and the decryption key is 6000. The encryption code is different, so the video is not seen.

Then let’s change decryption code to 600, keep the code are the same on the transmitter and receiver. Then we set it, when I click the write, it shows write error! Then close the connection, and open it again. When you see, welcom to you, then click write. “Write successful”. Now we have successfully set it, the video is received normally.

Now let’s change the encryption code to 6000, to change different encryption code, to see the video is seen or scrambled.
Then let’s set, look, our video on the monitor will immediately show this garbled video, you can’t see anything, It’s all garbled.

Ugbu a, then we set it back. The decryption is also set to 6,000. Let’s set it again, the setting is successful, Our video will start to work properly.

One more thing, adding encryption code is not add any delay.

ajụjụ: Why do transmitters and receivers need to support encryption and decryption functions?

A na-agbasa vidiyo FPV gị, Ndị ọzọ na-enyocha vidiyo gị dị ndụ n'otu oge?
