The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 or wider and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840 × 2160.[5][6] In 2015, the Ultra HD Forum was created to bring together the end-to-end video production ecosystem to ensure interoperability and produce industry guidelines so that adoption of ultra-high-definition television could accelerate. From just 30 in Q3 2015, the forum published a list up to 55 commercial services available around the world offering 4K resolution.[7]
The "UHD Alliance", an industry consortium of content creators, distributors, and hardware manufacturers, announced during a Consumer Electronics Show (CES) 2016 press conference its "Ultra HD Premium" specification, which defines resolution, bit depth, color gamut, high dynamic range (HDR) performance required for Ultra HD (UHDTV) content and displays to carry their Ultra HD Premium logo.[b]
Alternative terms
Ultra-high-definition television is also known as Ultra HD, UHD, UHDTV, and 4K.[13][14][15][16][17] In Japan, 8K UHDTV will be known as Super Hi-Vision since Hi-Vision was the term used in Japan for HDTV.[18][19] In the consumer electronics market companies had previously only used the term 4K at the 2012 CES but that had changed to "Ultra HD" during CES 2013.[16][17] "Ultra HD" was selected by the Consumer Electronics Association after extensive consumer research, as the term has also been established with the introduction of "Ultra HD Blu-ray".[20]
UHDTV-1 is 3840 pixels wide by 2160 pixels tall (8.3 megapixels), which is four times as many pixels as the 1920 × 1080 (2.07 megapixels) of current 1080pHDTV (full HDTV).
Also known as 2160p, and 4K UHD. Although roughly similar in resolution to 4K digital cinema formats, it should not be confused with other 4K resolutions such as the 4096 × 2160DCI 4K/Cinema 4K. The total number of pixels of RGB stripe type is 8.3 megapixels.
UHDTV-2 is 7680 pixels wide by 4320 pixels tall (33.18 megapixels), also referred to as 4320p and 8K UHD, which is sixteen times as many pixels as current 1080pHDTV, which brings it closer to the detail level of 15/70 mm IMAX.[14][23][24]NHK advertises the 8K UHDTV format with 22.2 surround sound as Super Hi-Vision, which can be broadcast with H.264 codecs.[25]
Color space, dynamic range, frame rate and resolution/aliasing
The human visual system has a limited ability to discern improvements in resolution when picture elements are already small enough or distant enough from the viewer. At some home viewing distances and current TV sizes, HD resolution is near the limits of resolution for the eye and increasing resolution to 4K has little perceptual impact, if consumers are beyond the critical distance (Lechner distance) to appreciate the differences in pixel count between 4K and HD. One exception is that even if resolution surpasses the resolving ability of the human eye, there is still an improvement in the way the image appears due to higher resolutions reducing spatial aliasing.
UHDTV provides other image enhancements in addition to pixel density. Specifically, dynamic range and color are greatly enhanced, and these impact saturation and contrast differences that are readily resolved greatly improve the experience of 4KTV compared to HDTV. UHDTV allows the future use of the new Rec. 2020 (UHDTV) color space which can reproduce colors that cannot be shown with the current Rec. 709 (HDTV) color space.[18]
In terms of CIE 1931 color space, the Rec. 2020 color space covers 75.8%, compared to coverage by the DCI-P3digital cinema reference projector color space of just 53.6%, 52.1% by Adobe RGB color space, while the Rec. 709 color space covers only 35.9%.[18] UHDTV's increases in dynamic range allow not only brighter highlights but also increased detail in the greyscale. UHDTV also allows for frame rates up to 120 frames per second (fps).[15][26]
UHDTV potentially allows Rec. 2020, higher dynamic range, and higher frame rates to work on HD services without increasing resolution to 4K, providing improved quality without as high of an increase in bandwidth demand.
History
2001–2005
Prototype camera head (2006)Prototype camera head (2009)
The first displays capable of displaying 4K content appeared in 2001, as the IBM T220/T221 LCD monitors.
NHK researchers built a UHDTV prototype which they demonstrated in 2003.[27] They used an array of 16 HDTV recorders with a total capacity of almost 3.5TB that could capture up to 18 minutes of test footage.[27] The camera itself was built with four 2.5-inch (64 mm) CCDs, each with a resolution of only 3840 × 2048.[27] Using two CCDs for green and one each for red and blue, they then used a spatial pixel offset method to bring it to 7680 × 4320.[27][c] Subsequently, an improved and more compact system was built using CMOS image sensor technology[28] and the CMOS image sensor system was demonstrated at Expo 2005, Aichi, Japan, the NAB 2006 and NAB 2007 conferences, Las Vegas, at IBC 2006 and IBC 2008,[29]Amsterdam, Netherlands, and CES 2009. A review of the NAB 2006 demo was published in a broadcast engineering e-newsletter.[30] Individuals at NHK and elsewhere projected that the timeframe for UHDTV to be available in domestic homes varied between 2015 and 2020 but Japan was to get it in the 2016 time frame.[31]
On December 31, 2006, NHK demonstrated a live relay of their annual Kōhaku Uta Gassen over IP from Tokyo to a 450 in (11 m) screen in Osaka. Using a codec developed by NHK, the video was compressed from 24Gbit/s to 180–600Mbit/s and the audio was compressed from 28Mbit/s to 7–28Mbit/s.[33] Uncompressed, a 20-minute broadcast would require roughly 4 TB of storage.
The SMPTE first released Standard 2036 for UHDTV in 2007.[34] UHDTV was defined as having two levels, called UHDTV1 (3840 × 2160) and UHDTV2 (7680 × 4320).[34][35]
In May 2007, the NHK did an indoor demonstration at the NHK Open House in which a UHDTV signal (7680 × 4320 at 60fps) was compressed to a 250Mbit/s MPEG2 stream.[36] The signal was input to a 300MHz wide band modulator and broadcast using a 500MHz QPSK modulation.[36] This "on the air" transmission had a very limited range (less than 2 meters), but shows the feasibility of a satellite transmission in the 36,000km orbit.[36]
In 2008, Aptina Imaging announced the introduction of a new CMOS image sensor specifically designed for the NHK UHDTV project.[37] During IBC 2008 Japan's NHK, Italy's RAI, BSkyB, Sony, Samsung, Panasonic Corporation, Sharp Corporation, and Toshiba (with various partners) demonstrated the first ever public live transmission of UHDTV, from London to the conference site in Amsterdam.[38][39]
On June 9, 2010, Panasonic announced that its professional plasma display lineup would include an 152-inch (3.9 m) plasma display with 4K resolution. At the time of announcement, it was the largest 4K display and the largest television.[40]
On September 29, 2010, the NHK partnered up and recorded The Charlatans live in the UK in the UHDTV format, before broadcasting over the internet to Japan.[41]
2011
On May 19, 2011, Sharp in collaboration with NHK demonstrated a direct-view 85 in (220 cm) LCD display capable of 7680 × 4320 pixels at 10 bits per channel.[42] It was the first direct-view Super Hi-Vision-compatible display released.[43]
Before 2011, UHDTV allowed for frame rates of 24, 25, 50, and 60fps.[35] In an ITU-R meeting during 2011, an additional frame rate was added to UHDTV of 120fps.[44]
2012
On February 23, 2012, NHK announced that with Shizuoka University they had developed an 8K sensor that can shoot video at 120fps.[45][46][47]
In April 2012, Panasonic, in collaboration with NHK announced a 145 in (370 cm) display (7680 × 4320 at 60fps), which has 33.2 million 0.417mm square pixels.[48]
In April 2012, the four major South Korean terrestrial broadcasters (KBS, MBC, SBS, and EBS) announced that in the future, they would begin test broadcasts of UHDTV on channel 66 in Seoul.[49][50] At the time of the announcement, the UHDTV technical details had not yet been decided.[49][50]LG Electronics and Samsung are also involved in UHDTV test broadcasts.[50]
In May 2012, NHK showed the world's first ultra-high-definition shoulder-mount camera.[51] By reducing the size and weight of the camera, the portability had been improved, making it more maneuverable than previous prototypes, so it could be used in a wide variety of shooting situations.[51] The single-chip sensor uses a Bayer color-filter array, where only one color component is acquired per pixel.[51] Researchers at NHK also developed a high-quality up-converter, which estimates the other two color components to convert the output into full resolution video.[51]
Also in May 2012, NHK showed the ultra-high-definition imaging system it has developed in conjunction with Shizuoka University, which outputs 33.2-megapixel video at 120fps with a color depth of 12bits per component.[52][53] As ultra-high-definition broadcasts at full resolution are designed for large, wall-sized displays, there is a possibility that fast-moving subjects may not be clear when shot at 60fps, so the option of 120fps has been standardized for these situations.[52] To handle the sensor output of approximately 4 billion pixels per second with a data rate as high as 51.2Gbit/s, a faster analog-to-digital converter has been developed to process the data from the pixels, and then a high-speed output circuit distributes the resulting digital signals into 96 parallel channels.[52] This 1.5 in (38 mm) CMOS sensor is smaller and uses less power when compared to conventional ultra-high-definition sensors, and it is also the world's first to support the full specifications of the ultra-high-definition standard.[52]
During the 2012 Summer Olympics in Great Britain, the format was publicly showcased by the world's largest broadcaster, the BBC,[54] which set up 15-meter-wide screens in London, Glasgow, and Bradford to allow viewers to see the Games in ultra-high definition.[55][56]
On May 31, 2012,[57] Sony released the VPL-VW1000ES 4K 3D Projector,[58] the world's first consumer-prosumer projector using the 4K UHDTV system, with the shutter-glasses stereoscopic 3D technology priced at US$24,999.99.[59][60]
On August 22, 2012, LG announced the world's first 3D UHDTV using the 4K system.[61]
On September 15, 2012, David Wood, Deputy Director of the EBU Technology and Development Department (who chairs the ITU working group that created Rec. 2020), told The Hollywood Reporter that South Korea plans to begin test broadcasts of 4K UHDTV next year.[63][64][65] Wood also said that many broadcasters have the opinion that going from HDTV to 8K UHDTV is too much of a leap and that it would be better to start with 4K UHDTV.[63] In the same article, Masakazu Iwaki, NHK Research senior manager, said that the NHK plan to go with 8K UHDTV is for economic reasons since directly going to 8K UHDTV would avoid an additional transition from 4K UHDTV to 8K UHDTV.[63]
On October 18, 2012, the Consumer Electronics Association (CEA) announced that it had been unanimously agreed by the CEA's Board of Industry Leaders that the term "Ultra High-Definition", or "Ultra HD", would be used for displays that have a resolution of at least 8 megapixels with a vertical resolution of at least 2,160 pixels and a horizontal resolution of at least 3,840 pixels.[66][67][68][69] The Ultra HD label also requires the display to have an aspect ratio of 16:9 or wider and to have at least one digital input that can carry and present a native video signal of 3840 × 2160 without having to rely on a video scaler.[66][67][68][69] Sony announced they would market their 4K products as 4K Ultra High-Definition (4K UHD).[70]
On October 23, 2012, Ortus Technology Co., Ltd announced the development of the world's smallest 3840 × 2160 pixel LCD panel with a size of 9.6 in (24 cm) and a pixel density of 458px/in.[71][72][73] The LCD panel is designed for medical equipment and professional video equipment.[71][72][73]
