  • NICAM compatible television signal converter
    Patent number: 5220602
    Abstract: A NICAM compatible baseband television signal converter is provided. A television signal including a NICAM digital audio subcarrier is converted to baseband and the NICAM subcarrier is filtered therefrom. The video and analog audio portions of the baseband television signal are demodulated. The demodulated video is descrambled and the demodulated analog audio is descrambled and/or volume controlled. The demodulated video and analog audio signals are then remodulated onto respective video and analog carriers. The filtered NICAM digital audio subcarrier is mixed with the video carrier to provide a modulated NICAM carrier. The remodulated video and analog audio signals are combined with the modulated NICAM carrier for output to a video appliance such as a television or video recorder.
