A film cadence in a video signal (VA) is detected in the following manner Successive classification indications (BCN, BCN−1, BCN−2,•••) are generated for successive images within the video signal. A classification indication belongs to a particular image and indicates whether that particular image is an original image or a repeat image. A condition is checked for at least X successive classification indications, X representing a natural number in a given range. The condition is that each one of the at least X successive classification indications is equal to the X-th previous classification indication. If the condition is true, a pattern indication (PI) is provided, which corresponds with the natural number that X represents. If the condition is false, the condition is checked anew with X representing another natural number in the given range.
