Q: What is DCDi by Faroudja?

A: Directional Correlation De-interlacing (DCDi®) by Faroudja is a video mode algorithm. It was initially designed for fast action video-based material. Its general purpose is to reduce jagged edges along diagonal lines caused by interpolation. Utilizing this algorithm, DCDi does not simply weave together two fields of video that match; it has to create new information through interpolation which "smooths" the diagonal edges. DCDi constantly keeps track of (monitors) edge transitions and fills in any of the gaps that need smoothing.
