Abstract

An apparatus (2) for use in the transmission of a video information signal by twisted pair conductors (6), comprises input means (31) for matching the impedance of a video in formation signal source (4), driving means (40) for respective conductors of a twisted pair (6) including a pair of differential line drivers, one being an inverting amplifier (42) and another a non-inverting amplifier (41), each amplifier (41, 42) being fed with the signal from the signal source (4) output and means (43) for matching the impedance of the twisted pair conductors (6). Signals carried on the twisted pair conductors (6) are thereby balanced to promote immunity against inductive and/or capacitive interference. <IMAGE>
