ABSTRACT:
A method of converting interlaced video to progressive video can include a series of steps. The method can include receiving a video signal representative of at least one picture and determining whether the picture is progressive. If the picture is progressive, a vertical synchronization signal is modified to create an association with a first field of the picture. Accordingly, a progressive video signal can be converted to an interlaced video signal associated with the vertical synchronization signal and the interlaced video signal can then be converted to a progressive video signal in correspondence with modifications made to the vertical synchronization signal.
