The Video Deinterlacer converts live incoming interlaced video streams into progressive video streams. Interlaced images may have temporal motion between the two fields that comprise an interlaced frame. The conversion to a progressive format recombines these two fields into one single progressive scan frame. The combining of interlaced video streams results in unsightly motion artifacts in the progressive output image. For this reason, the Video Deinterlacer can be configured to use three field buffers and produce progressive frames based on a combination of spatial and temporal processing. This core is part of Video processing sub system, refer to the Video Processing Subsystem LogiCORE PIP Product Guide ( PG231 )for more information on this IP.
