Method and apparatus for discriminating between movie film and non-movie film and generating a picture signal processing mode control signal
First Claim
1. A method of generating a control signal indicating whether a received picture signal originated from a movie-film source or from a non-movie-film source by a video camera for controlling a picture signal processing mode for the received picture signals, comprising the steps of:
- (a) determining first motion vectors for a first field of the received picture signals,(b) determining second motion vectors for a second field of the received picture signals,(c) comparing said first and second motion vectors and based upon said comparison generating a control signal indicating whether the received picture signal originated from a movie-film source or from a non-movie-film source by a video camera.

Abstract
In a method of controlling a picture signal processing mode, first and second motion vectors are determined (ME, DT) for first and second fields, and a picture signal processing mode control signal is obtained by comparing (DT, -, COMP-R) the first and second motion vectors. The control signal may be transmitted along with, for example, a HDTV signal to give an indication to a TV receiver whether the signal originated from movie-film or from non-movie-film or be generated within the receiver.
