Abstract

A video-disc recording and replay equipment is used to record and reproduce coloured pictures. The recorder comprises a television camera (111) which can produce three video signals corresponding to the three primary colours. It also has a switching unit (112), a video-disc recorder (113), a video disc reader (115) a picture screen (116), an identification unit (117) and a synchronisation unit (118). The camera (111) produces a signal (T) which drives the synchronisation unit (118). This unit (118) operates the switch unit (112) which gives one of the video signal to the next unit, and eventually to the disc, at every sixth frame of the picture.
