OEM Wireless COFDM Video Transmitter Module With HD-SDI Video Input H.265 Encoder
Brief introduction:
The COFDM video transmitter module has SDI/AHD (AV compatible) input interface, adopts COFDM modulation and H.265/H.264 encoding technology, which can complete video audio transmission with low latency in high-speed movement and non-line-of-sight (NLOS) conditions. The transmitter module consists of two boards (video encoder board and COFDM modulator board). It also provides one transparent transmission serial port (unidirectional).

The COFDM video transmitter module can operate in various functional modes with different firmwares. Settings can be clearly stated before shipment. The default regular functions as below:
The default normal function of the COFDM video transmitter module will be paired with our HD5 receiver module. The delay of the HD video displayed on the HDMI screen from the transmitter input to the receiver is about 200 ms to 250 ms.
