Ultrahigh-definition television (UHDTV) is now being studied as the most promising candidate for next-generation television beyond HDTV. It consists of extremely high-resolution imagery and multichannel 3-D sound to give viewers a stronger sensation of reality. Various aspects should be taken into account when determining UHDTV image format. Of those, it is believed that user visual experience is ... View full abstract»

This paper introduces a new wide-gamut RGB primary set and a new color-encoding method that are developed for ultrahigh-definition television (UHDTV). The extended gamut RGB-primary set compared with the conventional CRT-centric gamut is proposed in favor of inclusion of real-world surface colors and in consideration of the current and prospective colorimetric characteristics of flat panel display...

Color management has been well established for still images and professional videos but not for consumer videos. It is necessary to develop color management that is suitable for consumer videos. A color management system (CMS) renders reproduced color or preferred color on a display through video signal processing. A complete color management workflow includes color processing from a camera to a d... View full abstract»

Liquid crystal display (LCD) technology will struggle to display high resolution on screens as big as whiteboards. Yet there is demand also for less power consumption, 3-D images, and that the display should be able to see gestures and feel touch. Most of these features are possible with projection and wedge light guides make projection slim, but picoprojectors are so dim that many will be needed ... View full abstract»

High-definition television (HDTV) images are now commonly available and the recent trend of video applications is toward even higher spatial resolutions with higher pixel rates. To make such high-resolution video images possible, the sensor must have a line time, or one row time, of less than a few microseconds with a pixel rate greater than gigapixels per second. In this paper, the basics of comp... View full abstract»

Research and development of ultrahigh-definition imaging systems that go beyond high-definition television (HDTV) have converged in the field of “4K” and “8K” imaging systems. The 4K imaging systems are used for digital cinema, while the 8K systems have been developed for use in next-generation TV broadcasting systems. The latter at 60 frames/s represents the highest pi...

Japan Broadcasting Corporation (NHK) promotes research and development of Super Hi-Vision (SHV), an ultrahigh-definition TV system with 16 times the number of pixels of HDTV and with a 22.2 multichannel sound system. So far, three types of SHV displays have been developed, using liquid-crystal-on-silicon (LCOS) projection technologies. The three types are the pixel-offset method, the dual-modulati...

It is widely accepted that the emerging concept of immersive media is one of the key technologies for future entertainment. One feature of immersive media is to use large panoramic screens with ultrahigh resolution. This technology requires a completely new production grammar that is not necessarily compatible with conventional production formats. Against this background the paper describes a new ...

This article will describe the progress since 2000 on research and development in 2-D and 3-D scalable resolution display walls that are built from tiling individual lower resolution flat panel displays. The article will describe approaches and trends in display hardware construction, middleware architecture, and user-interaction design. The article will also highlight examples of use cases and th...

To help pave the way for Super Hi-Vision (SHV) broadcasting, we have developed a new codec system that can encode and decode SHV signals in real time. This is the third generation of SHV real-time hardware codec. This efficient compression system maintains high picture quality by using eight 1080/60p (60 frames/s) encoding units and a video format converter with signal compensation processing that...

Digital cinema is a promising application that utilizes high-speed optical networks to transfer super-high-definition (SHD) images. The networks are primarily used for distributing digital cinema contents in packet data form, and are also used to support new services such as the live streaming of musicals and sport games to movie theaters. While current transfer services offer high-definition (HD)... View full abstract»

This paper describes the recent progress of research and development on transmission technologies for Super Hi-Vision (SHV), which is the form of ultrahigh-definition television (UHDTV) with the highest resolution class. The paper covers the transmission systems for SHV program production and satellite broadcasting. For short-haul transmission, an optical digital interface for video equipment was ...

The growth in digital, stereographic motion pictures has been surprising and strong, providing a new revenue generator for the industry. After a sluggish start for the digital cinema industry, 3-D movies have become the primary driver of digital cinema adoption. Those experienced in digital stereographic techniques are clamoring for more tools and capabilities to support their creative visions. Me... View full abstract»

Three-dimensional imaging is still not in the full commercial stage, but its application is widening due to its capability of creating real-world-like environments. This capability is especially important in realizing reality communication and telepresence operations in medical and unreachable places. For these applications, technologies for interacting with objects in the 3-D image should also be... View full abstract»
