  • Wide band VCR with comb filter inhibition
    Patent number: 4831443
    Abstract: A super VHS VCR includes a comb filter for separating luminance and chrominance signals from a composite video signal to provide improved frequency recording characteristics. A timing circuit detects the television signal vertical interval, finds the horizontal lines that bear encoded Teletext data and inhibits comb filtering during the active video portion of the selected horizontal lines to protect any Teletext data from corruption by the comb filter action.
