Note(s): PATENT STATUS: Granted. Method and apparatus are disclosed for receiving an interlaced color video signal, and processing the signal to produce a progressively scanned video signal. An embodiment of the method of the invention includes the following steps: 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 the 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 the low pass luminance component; and combining the progressively scanned low and high pass luminance components. In a disclosed embodiment, the step of deriving, from the luminance component of the received signal, a low pass luminance component, comprises scan converting the progressively scanned high pass luminance component to an interlaced scanned high pass luminance component, and subtracting the interlaced scanned high pass luminance component from the luminance component of the received signal to obtain the low pass luminance component.
