ABSTRACT:
Prerecorded video discs will generally be provided with a program which has originally been recorded on film, which program is transformed into a television signal by scanning the film frames. Owing to the difference between the standards for film and television employed in the United States consecutive film frames always result in sets of unequal numbers of fields on the record carrier. Preferably an indication signal is added to each set of fields on the record carrier. The read apparatus comprises detection means for detecting said indication signal. This signal is used to ensure that in the still-picture mode, during which the same two fields on a track circumference of the record carrier are repeatedly read, two fields are read which belong to the same set and consequently stem from the same film frame.
