ABSTRACT:
A converter with which an extended definition (ED) video signal may be converted into a signal that may be recorded by a video recorder and with which a signal read out by a video reorder may be converted to an ED video signal. The ED video signal includes first lines having a first luminance signal (Y.sub.1) and a chrominance signal (C), and second lines having no chrominance signal but a second luminance signal (Y.sub.2) in the form of a modulated luminance signal with suppressed carrier. The converter includes a separation unit which receives the ED video signal from an input terminal and has three outputs. A first output couples the first luminance signal to a first output terminal via a first signal combination unit. A second output couples the chrominance signal to a second output terminal via a second combination unit. The third output is coupled to the first output terminal via a mixer circuit and the first combination unit.
