Abstract
A circuit for selecting one of a number of video signals to be processed by a television receiver. The circuit comprises diode means having inputs suitable for coupling to alternate sources of video signals. A bias source applies a bias voltage to the diode means and control means applies various control voltages to the diode means. The relationship of the control voltages to the bias voltage determines which of the alternate sources of video signals are coupled to the output of the diode means.
