Abstract

In a method for encoding a non-interlaced signal (60P) into an interlaced signal (60I) and an auxiliary signal, the interlaced signal (60I) is generated in dependence on the non-interlaced signal (60P), and the auxiliary signal is generated by furnishing regerneration coefficients enabling a reconstruction of non-encoded lines (o: D) of the non-interlaced signal (60P) in dependence on the interlaced signal (60I: A, B, C) and the regeneration coefficients. The invention is preferably applied in a method of processing non-interlaced signals by means of equipment, such as studio equipment, developed for processing interlaced signals.
