all about HD

High Definition Video generally refers to any video system of higher resolution than standard-definition (SD), i.e. NTSC, PAL and SECAM.

NEXT: Ultra High Definition TV in 2015

Super Hi-vision (Ultrahigh-Definition Wide-Screen System with 4000 Scanning Lines) is the technology developed by NHK Science & Technical Research Laboratories that delivers the images so real that viewers feel as if they were actually at the site of the broadcast and find themselves attempting to touch what’s on the screen. The large, wide-screen video images with the resolution equivalent to that of gravure printing strike viewers as a fresh surprise. The cutting-edge technology captures the attention of the international community.

- The system uses a video format with 7680 x 4320 pixels (16 times higher than standard HDTV system.) This world’s first video system with 4000 scanning lines delivers ultra-clear, realistic three-dimensional images that can be achieved only by ultrahigh-definition technology.

- The individual scanning lines are not visually noticeable even when relatively close to the screen, reflecting the high resolution of the system. What’s more, a wider viewing angle conveys a stronger sense of a reality.

- The new 3-D audio system with 24 loudspeakers dramatically enhances presence.

Super Hi-Vision, also known as Ultra High Definition Video, UHDV, Ultra High Definition Television, UHDTV and UHD is an experimental digital video format, currently proposed by NHK of Japan, the BBC, and RAI.

According to the Yomiuri Shimbun, the Japanese Ministry of Internal Affairs and Communications will be starting a public-private partnership to develop technology for UHDV in the hopes of setting an international standard for Super Hi-Vision in addition to broadcasting with it beginning in 2015.
