Abstract
A system for processing a video data stream has a data input to receive a video data stream with first and second fields of interlaced scan lines. The system has a resizing and filtering component to remove the first field of interlaced scan lines, thereby reducing the quantity of video data by one-half. The resizing and filtering component then resizes the remaining second field of interlaced scan lines by averaging pairs of sequential scan lines to produce averaged line pairs. Thereafter, the resizing and filtering component filters the averaged line pairs to remove any unwanted interlace flickering.
