Product Description
Wireless Video Transmitter Module COFDM Modular Mainboard With HDMI CVBS AV Input
Key Features
- COFDM modulation for NLOS (Non-Line-of-Sight) wireless video transmission
- H.265/H.264 video encoding supporting multiple video formats
- Dual video input via HDMI and AV interfaces with simultaneous compression and transmission
- AES256 encryption for data security
- Supports high-speed mobile transmission up to 800km/h, ideal for UAV/drone applications
Product Overview
This COFDM modular transmitter features HDMI/AV inputs with advanced COFDM modulation technology and H.265/H.264 encoding for reliable video/audio transmission in high-speed motion and NLOS conditions with minimal latency. The system comprises two interconnected boards (video codec encoder board and COFDM modulation board) with a flat cable connection, plus a transparent UART transmission channel.
