DScaler

DScaler is a piece of software that grabs analog, interlaced video, and deinterlaces it to make it a progressive scan feed, then allows scaling to any resolution for use on your computer monitor or projector. Analog, interlaced video are devices like VCRs, laserdisc, and game consoles output. Unlike most existing software for use with TV cards, DScaler implements sophisticated deinterlacing algorithms. Using such algorithms makes sure that each kind of video source is handled a different way. It provides the user with a level of image quality unknown to PC owners until now. Some of the techniques are: video source deinterlacing; inverse telecine detection: 2:2 (for PAL movies) as well as 3:2 (for NTSC movies) pulldown; automatic aspect ratio control; judder elimination. The image quality resulting from those complex operations is high and allows some people equipped with data capable projectors to feed them with progressive scan images.
