How does the FPV Video Scrambler hide your video from the same frequency receiver?

As a drone enthusiast, the first thing you should understand is that if your video is transmitted from the drone to the ground, the wirelessly transmitted video is not encrypted or decrypted, which means that other people using the same frequency can also receive your video, posing a huge safety hazard to the aircraft operator.

Why you need to use video scrambler and descrambler?

We understand the importance of privacy to you, so all our digital videos can be set with AES128-bit bank-level encryption and decryption. For analog video, we also attach great importance to it and have designed video scramblers and descramblers with up to 7679 algorithms feed.

We have adopted a special processing method. You can continue to use your FPV VTX and VRX. We only interfere with the video so that others cannot peek into your video and privacy. Sometimes this can protect your reputation and life. Please pay attention to your video privacy.

Although our video scrambler and descrambler tool is powerful, it is small in size and light in weight, only 4.4 grams, and will not add extra weight to your drone.

Although our video scrambler and descrambler tool is very simple to connect and only needs to be connected to your video cable, it has magical functions. As long as one end is added to it and the scrambling algorithm serial number you know is set, the video will be locked. Even if others receive your video through some special reception or frequency, it will still be a distorted screen without any content.

Our video scrambler and descrambler tool is powerful, small in size, and very cheap, making it affordable for anyone who values ​​video privacy.

Our FPV composite video scrambler is used in pairs. One is installed on the drone camera video output line and connected to the front of the VTX video transmitter. The video coming out of the camera has been scrambled. The other is installed behind the receiver on the ground to descramble the received video signal so that the video can be displayed normally on the display or the glasses.

We can customize the drone analog composite CVBS video scrambler, please contact us.

To make our FPV analog video scrambler lighter and smaller to reduce the weight of the drone. So our composite video scrambler is just a small module, it has no metal shell to protect the exposed circuit board, we’d better wear an anti-static ring during use to reduce the damage of static electricity on the human body to the circuit board.

For the same purpose of reducing weight, the interface of our circuit board is very small pins. When you use the USB serial port tool to connect it to the computer, there will often be poor contact and connection failure. So during the use of CVBS Scrambling Assistant software, if it prompts connection failure or write failure, you need to check whether its interface or pin is loose.

To reduce the weight of the analog video scrambling module on the drone, these FPV video scrambling modules are exposed without a shell. When we operate them, we need to pay attention to prevent static interference. It is best to wear anti-static gloves and wristbands.

How to test the FPV Video scrambler?

A video scrambler module works by deliberately altering the analog video signal (such as CVBS, or composite video) to make it unwatchable or unintelligible to unauthorized viewers. The process involves modifying key components of the video signal, such as the luminance, sync signals, or frequency, in a way that can only be reversed by a corresponding descrambler with the correct decoding algorithm or key.

Steps for CVBS video Scrambling work

CVBS Video Signal inputs

The video input of the cvbs video scrambler module connects to your video sources’s output, which typically adheres to the PAL, NTSC video standards.

CVBS Video Scrambling Process:

The scrambler alters the signal based on the selected scrambling method. Common methods include:

• Sync Suppression
  • Removes or distorts the horizontal and/or vertical sync pulses, preventing unauthorized TVs or devices from locking onto the signal. This results in a rolling or distorted picture.
• Inversion of lines
  • This effect inverts specific lines within the video signal, impacting luminance and/or chrominance.
  • Without a descrambler, the image looks like a mess of lines.
• Shifting the frequency
  • It changes the video or color signal frequencies to make them unidentifiable.
• Adding random noise overlay
  • The video has a noise signal added to it.
• Advanced Encryption
  • Parts of the signal are digitally encoded with encryption keys, necessitating a specific key for decoding and descrambling.

Key or Code Application

Some scramblers apply encryption keys or codes to control access. For example, only authorized receivers with the correct decryption key can descrambler the signal.

Output Signal:

The module outputs the scrambled CVBS signal, which is transmitted via coaxial cables, RF systems, or other wireless video transmission FPV VTX.

CVBS Video Descrambling

In fact, our scrambling module and descrambling module are the same, You should set the working role in the configuration software. To restore the original video:

A descrambler applies the reverse process:
Restoring sync pulses.
Reversing inversion patterns.
Using the correct descrambling feeder which you also set in the scrambling module. If the descrambling parameters feeder is incorrect, the output remains garbled.

Example Applications

Wireless Analog Video Transmission

• Used in drones or FPV VTX to protect video feeds. Otherwise other person can get your private video at the same wireless frequency. It is very dangers.
• Elevator video surveillance: Because many high-rise elevator surveillance uses wireless video transmission, in order to protect the privacy of users and ensure that only authorized people can receive, view and save elevator videos, the elevator’s wireless video needs to be scrambled.

CCTV Surveillance

Scrambling ensures security by preventing interception of video feeds over shared or unsecured lines.

Cable TV

Scrambling prevents unauthorized access to premium channels. Subscribers use a descrambler box to decode the signal.

Broadcasting

Protects content from being accessed by non-paying users or competitors.

Advantages of analog video Scrambling

• Security: Prevents unauthorized viewing or recording.
• Bandwidth Efficiency: Ensures only legitimate receivers process the signal.
• Cost-Effectiveness: Simple analog scrambling methods are cheaper compared to full digital encryption. Analog Video scrambler module cost at USD38, but with the digital AES128 encryption video transmitter cost at USD890.
