ABSTRACT:
A control network and method for a color television receiver is described for enabling and disabling the limiting action of a conventional ACL (Automatic Color Limiter) circuit, for varying the threshold at which a color killer circuit inhibits reproduction of color images, or for effecting both functions simultaneously. In the preferred embodiment, the control network includes a two-position switch by which the viewer can either increase or decrease the value of a reference signal to thereby control the degree of amplification of a received color signal. An amplifier is responsive to a reduction in the amplitude of the reference signal for substantially disabling the limiting action of the ACL circuit and for causing the color killer to inhibit reproduction of color images when a relatively small amplitude color signal is received. When operation of the switch increases the amplitude of the reference signal, the amplifier responds by enabling the limiting action of the ACL circuit and causing the color killer to inhibit reproduction of color images when a relatively larger amplitude color signal is received.
