Why 4K? The Picture's Clear(er)
3-D TV sales have flattened, so the industry is moving on to “sharper and brighter” 4K – or Ultra High-Definition Television. Europe’s Canal Plus and Sky Deutschland are already planning dedicated UHTV channels, Michael Grotticelli reports. If you’re wondering, 4K has resolution of 3840 x 2160, but Japan’s NHK is already working on 8K (7680 x 4320). (This compares with current HDTV’s 1920 x1080). While 8K won’t be around for another eight years or so, 4K was already being demonstrated on the floor of the IBC show in Amsterdam this week.
