A method and an arrangement for manufacturing a high-resolution digital master for filing cinematographic films and their conversion into different TV and multimedia standards, in which the overall picture and sound information associated with the cinematographic film is high-resolution scanned, digitized and stored. For creating a high-quality electronic duplicate of a film master for the purpose of document-secure filing or for manufacturing different TV and multimedia versions, picture and sound data prescriptions derived from the film for processing steps and parameters associated with the corresponding film frames are additionally stored.

A digital color television signal has its chrominance component, which is in the form of color difference signals, resolved into color hue and color saturation signals which are used to address a function memory which provides a pair of correction signals that are supplied to calculator circuits which respectively receive the color hue signal, the color saturation signal and the luminance signal as well as predetermined control signals previously stored which relate to the color sectors adjacent to the color sector in which the color hue signal is located. The calculation circuits respectively supply corrected color hue, color saturation and luminance signals. The color hue signal is additively corrected by a color hue correction signal and the color saturation signal is multiplicatively corrected by a saturation correction signal.
