If i understand you correctly it does not show the full picture in degraded quality (more compression artifacts, framedrops), but it takes the center part of the image (so perhaps the center 70%) and upscales it to full size. With proper upscaling algorithms this would result in a slightly blurry picture, but with (as it uses only 70% of the image) no compression artifacts or framedrops. Sounds like a smart idea. However, i just skyped and noticed nothing of the sort. framedrops and compression artifacts galore. :-/
