line-doubler, video scaler, de-interlacer.Basically, a scaler/line-doubler turns the interlaced NTSC signal from the DVD player into progressive video, in the process removing the scan lines, or at least making them a lot less noticeable. That's why the picture from a line-doubler is often called "cinema-like."
Many monitors nowadays have built-in line doubler circuitry, but the best performance is assured from a separate unit such as the DVDO iScan Pro. Better line-doublers will have a feature called "3:2 cinema pull-down" (or similar wording) that corrects the problems (motion artifacts, etc.) that result when the 24 fps of cinema are converted into 30 fps (60 when interlaced) on conventional video. It's a complicated subject--you can read all about it here (see link).
