(PhysOrg.com) -- With their immersive 3D capabilities, virtual-reality environments (VEs) provide the kind of intense visual experience that two-dimensional digital televisions could never to live up to. But digital TVs outperform VEs in one important way: They can play high-resolution video in real-time without a hitch, while VEs have trouble rendering the data-heavy video clips at a constant frame rate. http://www.physorg.com/news152981636.html Technology Wed, 04 Feb 2009 14:55:59 EST news152981636 Converter boxes.
