Abstract:
A method for playback of film with an analog optical sound track the method comprises the steps of forming an image of only said analog optical sound track. Storing the image and representing part of the stored image as a spatial image. Processing the spatial image to form a median value and converting the median value of the spatial image to a signal representative of an audio signal represented in said sound track. Repeating the representing and processing steps to form median values for all of the image of the analog optical sound track.
