ABSTRACT:
A method of detecting motion in a video image comprising the steps of connecting an MPEG compliant encoder to a video source that provides video images, compressing the video data in the video images and generating a compressed video image bit stream having a motion compensation component, receiving the generated compressed video image bit stream, comparing the motion compensation component to a threshold value, and indicating that motion has occurred if the motion compensation component is greater than the threshold value.
