摘要：
A method (500) of converting interlaced video to progressive video includes receiving a video signal (505) representative of at least one picture and determining whether the at least one picture is progressive (510). Responsive to the progressive picture determination, a vertical synchronization signal is selectively modified to identify whether a field previously sent and a field to immediately follow are from a same progressive picture (615, 640).
