We have developed a new motion detecting method for nonstandard speed play of a composite VTR. We introduce a new technique using temporal filter for nonstandard speed play and motion detection by level comparison. A picture quality in nonstandard speed play of VTR has been improved by using this method and motion-adaptive inter-field signal processing.
