CEDIA EducationBy CEDIA Manufacturers are always looking for ways to improve their products, especially in the field of technology. With display resolutions, cables, discs and 3D technology being revamped and reworked, TV displays are becoming more detailed, lifelike and visually appealing. Ultra HD-4K technology makes use of higher pixel density, larger screens and the human eyes’ visual acuity to create a more detailed, in-depth image on display screens. This white paper is a companion piece to CEDIA’s consumer-oriented “What is Ultra High Definition and Why Does it Matter?” (see below) and will focus on what Ultra HD-4K technology is in greater detail, examine where the technology is heading and discuss what this means for CEDIA members. This white paper is free to CEDIA members, and costs £5.99 for non-members. cedia.co.uk/cda_whitepapers.php?action=view&id=QEM9HW990871&r=O6O13Q227551&sub=O6O13Q227551 What is Ultra High Definition and Why Does it Matter? (for Consumers) The term “high definition” is a now-ubiquitous phrase which took the consumer electronics world by storm in the late ‘90s and early ‘2000s when the digital transition began and televisions moved away from analog and towards digital. These days, a new term is emerging: “Ultra High Definition” or “Ultra HD.” But for many home viewers who have only recently adopted HDTV and grown accustomed to the superior picture quality, the features and advantages of Ultra HD might still be a mystery. To begin with, this paper will first address the terminology associated with this technology. There have been many terms used and can cause some confusion even for the technology enthusiast. Terms such as “ultra high definition,” “UHD,” “UHDTV” and “4K” are all flooding the market. CEA recently determined that “Ultra HD” should be the term used by the industry when referring to 4K and 8K resolution and will be used in this white paper. cedia.co.uk/cda_whitepapers.php?action=view&id=QEM9EE789921&r=O6O13Q227551&sub=O6O13Q227551
