Overview This COFDM transmitter module features HDMI/AV inputs with COFDM
modulation technology and H.265/H.264 encoding for high-speed
motion and non-line-of-sight (NLOS) video transmission with low
latency. The module consists of two boards (video codec encoder
board and COFDM modulation board) connected via flat cable, and
includes one transparent transmission UART interface. Technical Specifications | Input/Output Interface |
