A television signal processing apparatus is responsive to a received television signal for translating the frequency spectrum thereof to a frequency band characterized by a fixed frequency carrier signal frequency modulated in accordance with a baseband audio signal. The frequency modulated carrier signal is combined with an unmodulated CW muting signal having a frequency approximately equal to the frequency of the carrier signal to facilitate remotely controlled muting of the baseband audio signal in accordance with the FM capture effect.
