ABSTRACT:
System and method for combining interlaced video frames. A method embodiment for displaying a de-interlaced video sequence includes receiving a video stream, decoding the video stream to produce a sequence of interlaced video fields, creating a first de-interlaced video frame by combining at least two interlaced video fields, determining a cadence of the first de-interlaced video frame, and outputting the first de-interlaced video frame in a next de-interlaced video frame display time slot if the first de-interlaced video frame has proper cadence, while if the de-interlaced video frame has a broken cadence, re-outputting a previously outputted de-interlaced video frame in the next de-interlaced video frame display time slot. A feed-forward control signal may be used to determine which de-interlaced video frame to output and helps to minimize latency as well as storage requirements.
