A technique for detecting original scan lines is disclosed. The technique involves receiving a deinterlaced signal with even scan lines and odd scan lines. After the deinterlaced signal is received, a determination is made as to whether the even scan lines or the odd scan lines are the original scan lines. In certain embodiments, an interlaced signal can be generated from the original scan lines. In other embodiments, an optimized deinterlaced signal can be generated using the original scan lines.
