Abstract
PURPOSE: To realize reduction of the dynamic range by transmitting the video signals with the polarity inverted with every horizontal synchronous signal.
CONSTITUTION: The DC level is set at DC level setting circuit 21 to the input signal sent from input terminal 1 at the transmission part to obtain the input signal for signal polarity inverting circuit 22. Switch 23 gives switching every synchronous signal to the signals sent from circuit 21 and the signals from circuit 22 via the synchronous signal given from horizontal synchronous circuit 24 in order to transmit these signals to transmission line 4. The signals sent from line 4 are applied to signal polarity inverting circuit 51 at reception part 5 as well as to switch 52. And switch 52 gives switching to the signals via the synchronous signal of synchronous circuit 53, thus obtaining the original signal waveform at terminal 7.
