ABSTRACT:
Apparatus is provided for recovering, from a composite video signal which is reproduced from successive record tracks on a record medium, a frequency-converted chrominance component that is substantially free of cross-talk components. The frequency-converted chrominance components which are recorded in adjacent tracks have chrominance carriers which exhibit a frequency interleaved relationship with respect to each other. During reproduction, at least the frequency-converted chrominance component, together with an accompanying cross-talk component, is reproduced from the respective tracks. A cross-talk separating circuit, including a comb filter, is supplied with the reproduced chrominance component and separates the cross-talk component therefrom. A combining circuit functions to combine the separated cross-talk component and the reproduced frequency-converted chrominance component to produce a frequency-converted chrominance component that is substantially free of cross-talk components. In accordance with one feature, the cross-talk free, frequency-converted chrominance component is supplied directly to the recording circuit of a video signal recorder.
