1. A method for receiving an interlaced color video signal, and processing said signal to produce a progressively scanned video signal, comprising the steps of:

  • scan converting, by field combining and high pass filtering, the luminance component of the received signal, to obtain a progressively scanned high pass luminance component;

    deriving, from said luminance component of the received signal, a low pass luminance component;

    scan converting, by line rate conversion, to progressively scanned format, the chrominance components of the received signal and said low pass luminance component; and

    combining the progressively scanned low and high pass luminance components.
