摘要:
Apparatus for the reproduction of video signals via an intermediate cine film includes a video signal source (1) and a marker generator (5) for marking the video signals. The marked signals are raecorded via a film recorder (9) onto a cine film (11) for archiving. Regeneration of the original video signal from the cine film (11) includes removing the marking from the film (11) using a scanner (33), a marker detector (39) and comparator (46) in order to provide unmarked signals for further broadcast, or the like.
