Toshiba today announced their XDE, or “eXtended Detail Enhancement” technology, which upconverts standard video DVDs at 420i resolution to high-defintion video at 720p, 1080i or 1080p.
T abandoned their HD DVD rival to Blu-ray back in February 2008, but let it be known the following month that they will try to stay in the game via unconversion. The result is XDE which promises one of better sharpness, enhanced contrast or nicer blues & greens (as compared to reg DVD) … you can’t have all three.
While Toshiba did not provide any tech specs that explain just how they plan to perform all of this video scaling, we’re predicting failure mainly because it’s not that easy to guess at missing information … upconverting from 720×480 all the way to 1920×1080 (eg), requires the creation of 1,728,000 new pixels from 345,600 old ones.
