Abstract

A video tuner (1), a video signal (recording and) reproducing arrangement (7) and a picture display unit (35) are coupled to each other via a switching circuit (9). The video tuner (1) can supply first and second video signals on its output (3), representing pictures having a first and a second aspect ratio respectively (4:3 and 16:9, respectively). These signals can be recorded and reproduced by the video signal (recording and) reproducing arrangement (7) and can be displayed with the correct aspect ratio by the picture display unit (35). In order to realize this, a control signal line (55) is arranged between a control signal output (4) of the tuner (1), a control signal input and output terminal (10) of the video signal (recording and) reproducing arrangement (7) and control signal inputs (36) of the picture display unit and (46) of the switching circuit and control signal detector (9, 45). The video tuner (1) produces a first or a second control signal (S1 and S2) on the output (4) depending on the aspect ratio of the pictures in the supplied video signal while the video signal (recording and) reproducing arrangement (7) produces a third or a fourth control signal on the control signal input and output terminal (10) depending on the aspect ratio of the pictures in the video signal being reproduced. The switching circuit and detector (9, 45) select between the control signals in such a way that if the first or the second control signal is applied, the output signal of the video tuner (1) is selected, and if the third or the fourth control signal is applied, the output signal of the video signal (recording and) reproducing arrangement (7) is transferred to the picture display unit (35). The picture display unit (35) selects between the control signals in such a way that video signals applied to the input (37) are displayed with the correct aspect ratio on the display screen (39).
