Abstract: An input digital video signal is converted to an output digital video signal having a different frame rate and a different number of pixel lines per frame. A first series of progressive scan format frames is formed from the input signal. Then a second series of frames is formed from the first series of frames using motion compensated temporal interpolation between successive frames of the first series in producing at least some of the frames of the second series so as to provide the difference in frame rate. Before or after the second series of frames is formed, vertical spatial interpolation is performed so as to provide the difference in the number of pixel lines per frame.
