COFDM mODULATOR

COFDM stands for Coded Orthogonal Frequency Division Multiplexing.

Essentially, it uses a technology similar to European digital television (DVB-T) for efficient compression and encoding of 1080p video and audio, thus achieving high-quality, interference-resistant wireless transmission over long distances.

The mini, lightweight wireless video transmitter for drones, robot dogs, or unmanned boats uses COFDM technology and assembled by HDMI, CVBS, SDI, AHD video input encoding boards with the COFDM modulator.
