A method and apparatus uses a spatial filter for a television recording and playback system using a spectral folding process, wherein the signal is modulated onto a folding carrier of (f h/2, f v/2), for separating the two-dimensional image spectral domain of the television signal into first and second regions that are either passed or attenuated, the partition between the regions being selected such that every point in the passed region has a mirror point mirrored about (f h/4, f v/4) in the attenuated region: and reconstructing the passed region after playback.
