Super Hi-Vision

Television has progressed from black-and-white TV, to color TV, to HDTV. Hi-Vision has become the global standard, and STRL is now expanding its research on Super Hi-Vision (UHDTV:Ultra high-definition TV), a television system for the future with audio and video providing a heightened sense of reality exceeding that of HDTV.

1995-Envisioning the New World of Super Hi-Vision

Super Hi-Vision

Although STRL began conducting R&D on a 2000 scan-line system in 1995, it quickly moved on to the goal of developing a 4000 scan-line system that would include cameras, recording equipment, and projectors. The prototypes were presented to the public for the first time in 2002.

In 2005, a Super Hi-Vision video system with a 22.2 multi-channel audio system was shown to the public at Expo 2005 in Aichi, Japan. The world's first permanent Super Hi-Vision theater, "Theater 4000", opened at the Kyushu National Museum in Dazaifu, Fukuoka Prefecture in October of that same year. Super Hi-Vision has since been shown at various broadcasting trade shows, including NAB, IBC, BCA and CEATEC, and proceedings are underway to standardize it internationally.

During this time, improvements were made to the camera, projector, and recording equipment, new compression and encoding technologies were developed, and transmission tests using fiber optics and satellites were conducted.

The Super Hi-Vision video format has 16 times more pixels per frame than Hi-Vision (7680 x 4320, or about 33 Mega-pixels) and a progressive-scan frame rate of 60 Hz. The audio format is 22.2 multi-channel, and it reproduces sound in all six directions surrounding the viewer (in front, behind, left, right, above and below). Standardization of Super Hi-Vision is going forward at ITU-R and SMPTE (ITU-R recommendation BT.1769, SMPTE 2036).

The current goal is to begin test broadcasting in 2020, and STRL is developing the necessary broadcast systems to distribute Super Hi-Vision programs and receivers, including home displays and audio equipment. Super Hi-Vision requires a wide range of new elemental technologies, and the results of such R&D will have applications in various new media.
