High Quality Video on MultiMedia PCs

Displaying broadcast video on a MultiMedia PC, implies the use of video format conversion (VFC) techniques, as computer displays and television receivers use quite distinct scanning rasters. VFC consists of spatial scaling, deinterlacing and picture rate conversion. Although scaling is rather straightforward, the other two tasks are far from trivial, and advanced motion compensated interpolation techniques are necessary to achieve a performance level that can compete with that of a standard TV. This paper discusses the options for picture rate conversion, and shows how even advanced motion compensated algorithms can run real time on a currently available programmable device.
