Motion sequence pattern detector for video
First Claim
1. A motion sequence pattern detector for detecting a periodic pattern of motion sequences within a video temporal signal stream, comprising first motion detector means for detecting the presence of motion by comparing spatial picture data to similarly located successive spatial picture data within the video temporal signal stream and for thereupon putting out a first motion detection signal for each comparison of said data, and logic means responsive to a sequence of first motion detection signals for detecting said periodic pattern of motion sequences within the video temporal signal stream.

Abstract
A motion sequence pattern detector detects a periodic pattern of motion sequences within a succession of video fields, such as film mode or progressive scan mode and comprises a motion detector for detecting the presence of motion from increment to increment within predetermined increments of the succession of video fields and for thereupon putting out a first motion detection signal for each said increment, and logic circuitry responsive to the first motion detection signal for detecting the periodic pattern of motion sequences within the succession of video fields.
