DCDi technology is primarily used for improving the image quality of low resolution images. The DCDi algorithm starts by deinterlacing images, using a number of techniques, including "Bad Edit Detection", which detects 24 frame/s film sources in 30 frame/s video streams, converting the stream back to 24 frame/s. The DCDi algorithm also employs edge detection to find the moving edges in a scene and adjust the angle of interpolation at each pixel so that the interpolation always follows the edge instead of crossing it. This eliminates staircasing and/or jagged edge artifacts.
These techniques won an Emmy Award from National Academy of Television Arts and Sciences in 2001.
