Abstract
In a system in which alternate lines of one color television video signal normally are delayed half the period of the color subcarrier at a transmitting terminal to minimize the cross modulation of the color subcarrier with the color subcarrier of another video signal amplified in a common amplifier such as in a satellite transponder, an intermediate line delay unit at the receiving terminal is normally operative to delay intermediate lines of the one video signal half the period of the color subcarrier, and is automatically inhibited from delaying intermediate lines of the one video signal when the received alternate lines of said one video signal are for any reasons not delayed at the transmitting terminal.
