Abstract
A method and apparatus for displaying a picture film via a video-disc which consists in analyzing the pictures of the film on a plurality of interlaced fields which are successively recorded onto a video-disc. These fields are then read simultaneously on this video-disc and the video signal thus obtained are used for modulating a display apparatus scanned according to a primary raster with a superimposed raster. A coding device is used for mixing the video signals and producing signals for synchronizing the display apparatus.
