Abstract
Methods and systems for pre-processing a progressive scan signal comprise: receiving by a processor thea progressive scan signal; detecting an amount of vertical motion present in the progressive scan signal; low pass filtering the progressive scan signal in a vertical domain as a function of the amount of vertical motion present to generate a pre-filtered progressive signal; and interlacing the pre-filtered progressive signal to generate an interlaced signal having a minimal amount of artifacts.
