Video information is recorded and stored on an information carrier in the form of a signal sequence corresponding to a sequential scan of two images of a moving colored motif. The two images correspond to interlaced color extracts. The recorded signal sequence is divided into two, one for each of the two images and these split into three primary color signals for application to a domestic color television receiver set.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS As will be seen from FIG.
1, the motif 1 is reproduced in two images 4 and 5 by means of a lens 2 and an optical image splitter 3.
By means of two photo-electric scanners 6 and 7 these two images 4 and 5 are each converted into electrical signals.
In this way the space-related pictorial information is converted into time-related signal information.
By means of a commutator 8 a signal sequence is formed which contains the signal informations associated with the images 4 and 5 in sequentially interlaced- or intermeshed form.
The interlacing, or intermeshing may be arranged in such a way that, for example, the signal information in signal sequence 9 corresponds to one dot in one line, or to one half frame or picture, or to one full frame or picture of images 4 and 5.
The signal sequence 9 is recorded and stored on an information- or data carrier, such as a moving magnetic tape 10 as shown.
For reproduction, the recorded signal sequence 9 is picked up from the moving magnetic tape 10 and fed sequentially by commutator 11 to two different matrices 12, 13 The matrices 12, 13 are color signal separators as described with respect to matrix 35 of FIG.

30, 1979, the disclosure of which is incorporated herein by reference.
Such matrices process the signal information received into separate color signals of the kind required by a conventional domestic color television receiver set 15.
The color signals are fed to this set either directly, or, where applicable, through an intervening device 14, e.
g.
a PAL coder with subsequent high frequency modulation.
The device 14 performs its function by generating a composite video signal modulating the usual broadcast frequency carrier signal, as will be apparent to anyone skilled in the art.
The commutator 8 may actually be dispensed with if, as shown in FIGS.
7 and 8, the scanners 6,7 operate in such a way that only one of the two picture informations is effectively applied in sequential alternation
