People who have seen UHDV in operation have commented that the image quality is so good that it approaches the experience of "being there." Some observers even reported vertigo from observing fast-changing images without the accompanying sensation of physical motion. UHDV was developed by engineers at the Japan Broadcasting Corporation (NHK). In a UHDV video image, there are 4000 scanned horizontal lines per frame. This compares with 1000 lines per frame in HDTV images, and 625 lines per frame in conventional analog TV broadcasts. In experiments conducted by NHK, a charge-coupled device (CCD) camera has been used to provide the necessary detail in the captured images. The storage requirements are considerable. For example, 18 minutes of UHDV programming requires approximately 3.5 terabytes of disk space. ______________________ RELATED TERMS: resolution http://whatis.techtarget.com/definition/0,,sid9_gci212895,00.html?track=NL-34 pixel http://whatis.techtarget.com/definition/0,,sid9_gci212793,00.html?track=NL-34 high definition television http://whatis.techtarget.com/definition/0,,sid9_gci213996,00.html?track=NL-34 charge-coupled device http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci295633,00.html?track=NL-34 ______________________ SELECTED LINKS: CDFreaks.com describes a demonstration of UHDV and provides more technical details. http://www.cdfreaks.com/news2.php?ID=8067 ______________________ TODAY'S TECH NEWS: CRITICAL WINDOWS, EXCHANGE ALERTS ISSUED Microsoft issued five critical alerts today, four for Windows and one for Exchange 2000 Server. http://searchsecurity.techtarget.com/originalContent/0,289142,sid14_gci932286,00.html?track=NL-34 SIEBEL GETS ACQUISITIONS FEVER Two weeks after unveiling its own hosted software, the CRM market leader is buying out hosted provider UpShot.
