Abstract
Given an incoming stream of interlaced video, data for each field is analyzed to detect a progressive frame cadence. If a progressive frame cadence is detected, a set of instructions is generated to instruct a de-interlacing unit which fields were mastered from the same progressive frame. The similarity in motion between two consecutive fields and the correlation between two consecutive fields is used to detect the presence of cadences and breaks in cadences. Breaks in cadences are continuously detected in order to characterize the source as video and prevent false detection of cadences.
