FPV 비디오 스크램블러는 동일한 주파수 수신기에서 비디오를 어떻게 숨깁니까??

드론 매니아로서, 가장 먼저 이해해야 할 것은 비디오가 드론에서 지상으로 전송된다는 것입니다., 무선으로 전송된 영상은 암호화되거나 복호화되지 않습니다, 이는 동일한 주파수를 사용하는 다른 사람들도 귀하의 비디오를 수신할 수 있음을 의미합니다., 항공기 운영자에게 큰 안전 위험을 초래.

비디오 스크램블러와 디스크램블러를 사용해야 하는 이유?

우리는 귀하의 개인정보 보호가 얼마나 중요한지 잘 알고 있습니다., 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, 오직 4.4 그램, 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, 제발 연락하다 우리를.

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.

FPV 비디오 스크램블러를 테스트하는 방법?

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.

CVBS 비디오 스크램블링 작업 단계

CVBS 비디오 신호 입력

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 비디오 스크램블링 프로세스:

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.

키 또는 코드 신청

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

출력 신호:

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

CVBS 비디오 디스크램블링

사실은, 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.

예시 애플리케이션

무선 아날로그 비디오 전송

• 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 감시

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

케이블 TV

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

방송

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

아날로그 비디오 스크램블링의 장점

• 보안: 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.
