Ultra high definition television (also known as Ultra HD television or UHDTV) includes 4K UHD (2160p) and 8K UHD (4320p), which are two digital video formats proposed by NHK Science & Technology Research Laboratories and defined and approved by the International Telecommunication Union (ITU). 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 at least 16:9 and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3,840 × 2,160 pixels.

[edit] Alternative terms

Ultra high definition is also known as Ultra HD, UHD, and UHDTV.[1][2][3][4][5] In Japan, 8K UHDTV will be known as Super Hi-Vision since Hi-Vision was the term used in Japan for HDTV.[6][7] Companies had previously only used the term 4K at the 2012 International CES but that had changed to Ultra HD during the 2013 International CES.[4][5] The Ultra HD term is an umbrella term that was selected by the Consumer Electronics Association after extensive consumer research.[8]

[edit] Technical details

[edit] Resolution

Two resolutions are defined as UHDTV:[1][2][3]

  • 4K UHDTV (2160p) has a resolution of 3840 × 2160 (8.3 megapixels), 4 times the pixels of 1920 × 1080 (2.1 megapixels).
  • 8K UHDTV (4320p) has a resolution of 7680 × 4320 (33.2 megapixels), 16 times the pixels of current 1080p HDTV, which brings it closer to the detail level of 15/70mm IMAX.[2][9][10] NHK advocates the 8K UHDTV format with 22.2 surround sound as Super Hi-Vision.

The p in 2160p and 4320p stand for progressive scan or non-interlaced.

[edit] Color space and frame rate

The Rec. 2020 (UHDTV) color space can reproduce colors that can not be shown with the Rec. 709 (HDTV) color space.[6] In coverage of the CIE 1931 color space the Rec. 2020 color space covers 75.8%, digital cinema covers 53.6%, the Adobe RGB color space covers 52.1%, and Rec. 709 covers 35.9%.[6] Rec. 2020 allows for frame rates up to 120 frames per second (fps).[11][3]

[edit] History

[edit] 2003–2011

NHK researchers built their own UHDTV prototype from scratch, which they demonstrated in 2003.[13] They used an array of 16 HDTV recorders with a total capacity of almost 3.5 TB that could capture up to 18 minutes of test footage.[13] The camera itself was built with four 2.5 inch (64 mm) CCDs, each with a resolution of only 3840 × 2048.[13] 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.[13][14] Subsequently, an improved and more compact system was built using CMOS image sensor technology[15] 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,[16] Amsterdam, Netherlands, and CES 2009. A review of the NAB 2006 demo was published in a Broadcast Engineering e-newsletter.[17] The final goal is for UHDTV to be available in domestic homes, though the timeframe for this happening varies between 2015 to 2020 but Japan and China may get it in the 2013–2014 time frame.[18]

On November 2, 2006, NHK demonstrated a live relay of a UHDTV program over a 260 kilometer (km) distance by a fiber-optic network.[19] Using dense wavelength division multiplex (DWDM), 24 Gbit/s speed was achieved with a total of 16 different wavelength signals.[19]

On December 31, 2006, NHK demonstrated a live relay of their annual Kōhaku Uta Gassen over IP from Tokyo to a 450 in (11.4 m) screen in Osaka. Using a codec developed by NHK, the video was compressed from 24 Gbit/s to 180–600 Mbit/s and the audio was compressed from 28 Mbit/s to 7–28 Mbit/s.[20] Uncompressed, a 20-minute broadcast would require roughly 4 TB of storage.

The SMPTE first released Standard 2036 for UHDTV in 2007.[21] UHDTV was defined as having two levels called UHDTV1 (3840 × 2160 or 4K UHDTV) and UHDTV2 (7680 × 4320 or 8K UHDTV).[21][22]

In May 2007, the NHK did an indoor demonstration at the NHK Open House in which a UHDTV signal (7680 × 4320 at 60 fps) was compressed to a 250 Mbit/s MPEG2 stream.[23] The signal was input to a 300 MHz wide band modulator and broadcast using a 500 MHz QPSK modulation.[23] This "on the air" transmission had a very limited range (less than 2 meters), but shows the feasibility of a satellite transmission in the 36,000 km orbit.[23]

In 2008, Aptina Imaging announced the introduction of a new CMOS image sensor specifically designed for the NHK UHDTV project.[24] 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.[25][26]

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.[27]

On May 19, 2011, SHARP in collaboration with NHK demonstrated a direct-view 85 inches (Bad rounding here220 cm) LCD display capable of 7680 × 4320 pixels at 10 bits per pixel.[28] It was the first direct-view Super Hi-Vision-compatible display to be released.[29]

Before 2011, UHDTV allowed for frame rates of 24, 25, 50, and 60 fps.[22] In an ITU-R meeting during 2011, an additional frame rate was added to UHDTV of 120 fps.[30]

[edit] 2012

On February 23, 2012, NHK announced that with Shizuoka University they had developed an 8K sensor that can shoot video at 120 fps.[31][32][33]

In April 2012, NHK (in collaboration with Panasonic) announced a 145 in (370 cm) display (7680 × 4320 at 60 fps), which has 33.2 million 0.417 mm square pixels.[34]

In April 2012, the four major 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.[35][36] At the time of the announcement, the UHDTV technical details had not yet been decided.[35][36] LG Electronics and Samsung will also be involved in the test broadcasts of UHDTV.[36]

In May 2012, NHK showed the world's first ultra-high-definition shoulder-mount camera.[37] By reducing the size and weight of the camera, the portability had been improved, making it more maneuverable than previous prototypes, so it can be used in a wide variety of shooting situations.[37] The single-chip sensor uses a Bayer color-filter array, where only one color component is acquired per pixel.[37] Researchers at NHK have also developed a high-quality up-converter, which estimates the other two-color components to convert the output into full resolution video.[37]

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 120 fps with a color depth of 12 bits.[38][39] 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 60 fps, so the option of 120 fps has been standardized for these situations.[38] To handle the sensor output of approximately 4 billion pixels per second with a data rate as high as 51.2 Gbit/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.[38] 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.[38]

During the 2012 Summer Olympics in Great Britain, the format was publicly showcased by the world's largest broadcaster, the BBC,[40] which set up 15 meter wide screens in London, Glasgow, and Bradford to allow viewers to see the Games in ultra-high definition.[41][42]

On May 31, 2012,[43] Sony released the VPL-VW1000ES 4K 3D Projector,[44] 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.[45][46]

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 Korea plans to begin test broadcasts of 4K UHDTV next year.[49][50][51] 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.[49] 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.[49]

On October 18, 2012, the Consumer Electronics Association (CEA) announced that it had been unanimously agreed on by a vote of 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.[52][53][54][55] The Ultra HD label also requires the display to have an aspect ratio of at least 16 x 9 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.[52][53][54][55] Sony announced that their 4K products will be marketed as "4K Ultra High-Definition (4K UHD)".[56]
