The development most are hoping will do the trick is a display technology known as Ultra High-Definition, which offers four times the resolution of today's most advanced "1080p" HDTV sets. No question, Ultra HD provides stunning images--at least when displaying content created in the new "4K" video format. Unfortunately, only a handful of feature films (including "The Amazing Spider-Man", "Prometheus" and "The Hobbit") have been shot with 4K-capable cameras. Will 4K follow 3D's fate? It is far too early to say. But 4K television--far more than 4K cinema--faces some formidable obstacles. As with 3D television, the new 4K television format takes its lead from Hollywood. The existing wide-screen digital format used in cinemas is 1,998 pixels wide and 1,080 pixels tall. The 4K film standard has twice the resolution vertically and twice horizontally--ie, 3,996 pixels across the frame and 2,160 down--making it four times sharper all round. By contrast, the 4K format used in television is slightly narrower, having 3,840 pixels across and 2,160 pixels down. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
