Abstract

A method of determining one or more characteristics of a content stream (16) comprising a sequence (18) of frames (20), the method comprising the steps of receiving the sequence of frames, for each of a plurality of frames in the sequence of frames: measuring an attribute of one or more portions (34) of the frame, calculating a fingerprint (28) from the measured attribute (s), accessing a timetable (30) of predetermined fingerprints (28) for the content stream, and identifying the calculated-fingerprint (28) in the timetable (30). Finally, the process determines the (or each) characteristic of the content stream (16) (such as the speed and/or direction of the content streann) from at least two of the calculated and identified fingerprints (28).
