NTSC FPV Video Scrambler Transmitter Receiver Decryption Encryption Module

• CVBS video stream encryption and decryption module, paired for use (one for transmitter, one for receiver)
• FPGA digital encryption and decryption processing with high-strength 32-bit password (up to 2³² combinations)
• Minimal video latency (under 1ms) for encryption/decryption processing
• Supports PAL and NTSC analog video streams including FPV cameras and thermal imaging cameras
• Single hardware module configurable for encryption or decryption via dip switch
• Password configuration through serial port interface
• Compatible with all FPV VTX systems, compact square layout for easy integration
• Enhances FPV security and prevents unauthorized viewing of private video feeds

The module collects CVBS video and performs analog-to-digital conversion. The digital signal is then encrypted through FPGA processing, with the video image being reprocessed before digital-to-analog conversion outputs standard CVBS to the transmitter.

The received CVBS video signal undergoes analog-to-digital conversion, with the digital signal being decrypted through FPGA processing. After image reprocessing and digital-to-analog conversion, the module outputs standard CVBS to the display.

The SAC module measures 34.5×34.5mm with a top height under 3mm and bottom height under 1mm. Board thickness is 1.2mm with four corner mounting holes (2.5mm diameter). Total weight is 4.3 grams.

The switch determines module function: "ON" position (left) for encryption, "I" position (right) for decryption.
