A system for recording and reproducing an extended definition (ED) video signal in/from a track on a magnetic record carrier wherein an ED video signal, such as a PAL-PLUS 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 recording device includes a first signal path (11,31,32,16) for processing the first luminance signal, a second signal path (11,18) for processing the chrominance signal and a third signal path (10,30,32,16) for processing the second luminance signal prior to the three signals being combined (22) and recorded on the record carrier. The reproducing device also includes a first (48,50) a second (52,53) and a third signal path (48,73,83) for processing the first luminance signal, the chrominance signal, and the second luminance signal, respectively. Furthermore, a converter is described with which an ED video signal may be converted to a signal that may be recorded by a video recorder and with which a signal read out by a video recorder may be converted to an ED video signal.
