Abstract
In order to enable film frames of a film standard in which the number of film frames per second differs from the number of video pictures per second of the television standard in use with a gain of playing time, to allow still-picture operation on every turn, and to enable the picture numbers to be inserted on one radius, it is proposed to record one film frame as two video fields in every turn of the disc and to bring the number of video fields reproduced per second into conformity with the specified number of film frames per second by means of a pattern of forward and/or backward jumps effected during reproduction from the disc.
