The document describes the specifications of the ST6000TBH wireless video transmitter and receiver. Some key points: 1) The transmitter uses COFDM modulation to provide stable transmission over long distances, up to 80km in line-of-sight environments. It supports MPEG-2 video compression for DVD quality video. 2) The transmitter operates on lithium battery power and supports mobile and non-line-of-sight transmission. It has AES 128-bit encryption for security and low latency. 3) The transmitter and receiver have modular, compact designs and can operate on several frequency bands including VHF, UHF, and L-band. They are waterproof and shockproof.
