DScaler project is an ongoing attempt to get the best possible video quality from a Windows PC. DScaler is an application that resizes the video by using a PC with high performance and BT8x8 TV capture card. This software turns a PC into a line doubler with high quality. It captures interlaced video and deinterlaces into progressive scan streams for scaling to any resolution to use on your computer screen or projector. The interlaced video is a device such as VCRs, laserdisc and output game consoles. Unlike most existing software for use with TV cards, DScaler implements very sophisticated algorithms. These algorithms ensure that each type of video source is treated differently. It provides high image quality that PC owners have never seen before.
