| Zusammenfassung: | An apparatus for carrying out the Y/C separation of a composite color video signal used in a television receiver, a video cassette recorder and other and for carrying out the Y/C separation of various signals superposed on the video signal in the vertical retrace interval thereof, without distorting the various signals is disclosed in which apparatus a switching operation is preformed so that the composite color video signal itself is used as a luminance signal in the teletext period of the vertical retrace interval of the composite color video signal, and a Y/C separator (25b) of the non-correlation type is switched to operate in the remaining period of the vertical retrace interval. |
