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. Technical Specifications | Input/Output Interfaces |
