The author describes the general theory of TV standards conversion by fixed interpolation, temporal interpolation, vertical interpolation and adaptive interpolation. Factors considered include the scanning structure, video signal spectra, interpolation aperture frequency response, temporal component generation, aspect ratios and picture quality. Test results are given for up-conversion and down-conversion
