Abstract

A description is given of a system for recording and reproducing an extended definition (ED) video signal in/from a track on a magnetic record carrier. An ED video signal, such as a PAL-PLUS video signal, comprises first lines having a first luminance signal (Y1) and a chrominance signal (C), and second lines comprising no chrominance signal but a second luminance signal (Y2) in the form of a modulated luminance signal with suppressed carrier. The recording device in the system comprises 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 in the system 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. Various recording devices and associated reproducing devices are described. Furthermore, converter means are 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.
