A 3D television being showcased at a trade show.

3D television(3DTV) istelevisionthat conveysdepth perceptionto the viewer by employing techniques such asstereoscopicdisplay,multi-viewdisplay,2D-plus-depth,or any other form of3D display.Most modern 3Dtelevision setsuse anactive shutter 3D systemor apolarized 3D system,and some areautostereoscopicwithout the need of glasses. As of 2017,most 3D TV sets and services are no longer available from manufacturers.[1]

History

[edit]
Further information:3D film

Thestereoscopewas first invented bySir Charles Wheatstonein 1838.[2][3]It showed that when two pictures are viewed stereoscopically, they are combined by the brain to produce 3Ddepth perception.The stereoscope was improved by Louis Jules Duboscq, and a famous picture ofQueen Victoriawas displayed atThe Great Exhibitionin 1851. In 1855 theKinematoscopewas invented. In the late 1890s, the British film pioneerWilliam Friese-Greenefiled a patent for a 3D movie process. On 10 June 1915, former Edison Studios chief directorEdwin S. Porterand William E. Waddell presented tests in red-greenanaglyphto an audience at the Astor Theater in New York City and in 1922 the first public 3D movieThe Power of Lovewas displayed.

Stereoscopic 3D television was demonstrated for the first time on 10 August 1928, byJohn Logie Bairdin his company's premises at 133 Long Acre, London.[4]Baird pioneered a variety of 3D television systems using electro-mechanical and cathode-ray tube techniques. The first 3D TV was produced in 1935, and stereoscopic 3D still cameras for personal use had already become fairly common by the Second World War. Many 3D movies were produced for theatrical release in the US during the 1950s just when television started to become popular. The first such movie wasBwana DevilfromUnited Artiststhat could be seen all across the US in 1952. One year later, in 1953, came the 3D movieHouse of Waxwhich also featuredstereophonic sound.Alfred Hitchcockproduced his filmDial M for Murderin 3D, but for the purpose of maximizing profits the movie was released in 2D because not all cinemas were able to display 3D films. In 1946 theSoviet Unionalso developed 3D films, withRobinzon Kruzobeing its first full-length 3D movie.[5]People were excited to view the 3D movies, but were put off by their poor quality. Because of this, their popularity declined quickly. There was another attempt in the 1970s and 1980s to make 3D movies more mainstream with the releases ofFriday the 13th Part III(1982) andJaws 3-D(1983).[6]

Matsushita Electric(now Panasonic) developed a 3D television that employed anactive shutter 3D systemin the late 1970s. They unveiled the television in 1981, while at the same time adapting the technology for use with the firststereoscopic video game,Sega's arcade gameSubRoc-3D(1982).[7]3D film showings became more popular throughout the 2000s, culminating in the success of 3D presentations ofAvatarin December 2009 and January 2010.[8]

Though 3D movies were generally well received by the public, 3D television did not become popular until after theCES2010 trade show, when major manufacturers began selling a full lineup of 3D televisions, following the success ofAvatar.[9][10]Shortly thereafter, consumer and professional3D camcorderswere released to the public by Sony and Panasonic.[11][12][13]These used two lenses, one for each eye. According to DisplaySearch, 3D television shipments totaled 41.45 million units in 2012, compared with 24.14 in 2011 and 2.26 in 2010.[14]In late 2013, the number of 3D TV viewers started to decline,[15][16][17][18][19]and in 2016, development of 3D TV is limited to a few premium models.[20]Production of 3D TVs ended in 2016.[21]

Technologies

[edit]

There are several techniques to produce and display 3D moving pictures. The following are some of the technical details and methodologies employed in some of the more notable 3D movie systems that have been developed.

The future of 3D television is also emerging as time progresses. New technology like WindowWalls (wall-size displays) andVisible light communicationare being implemented into 3D television as the demand for 3D TV increases. Scott Birnbaum, vice president of Samsung's LCD business, said that the demand for 3D TV would skyrocket in the next couple of years, fueled by televised sports (but this did not happen). One might be able to obtain information directly onto their television due to new technologies like the Visible Light Communication that allows for this to happen because the LED lights transmit information by flickering at high frequencies.[22]

Displaying technologies

[edit]
Functional principle of active shutter 3D systems.
Functional principle of polarized 3D systems.

The basic requirement is to display offset images that are filtered separately to the left and right eye. Two strategies have been used to accomplish this: have the viewer wear eyeglasses to filter the separately offset images to each eye, or have the light source split the images directionally into the viewer's eyes (no glasses required).[23]Common 3D display technology for projecting stereoscopic image pairs to the viewer include:

In aCEATEC2011 exhibition,Hitachireleased glasses-free 3D projection systems that use a set of 24 projectors, lenses, and translucent half mirrors to superimpose 3D images with a horizontal viewing angle of 60 degrees and a vertical viewing angle of 30 degrees. Besides Hitachi,Sonyis also working on similar technologies.[24]

Single-view displays project only one stereo pair at a time. Multi-view displays either use head tracking to change the view depending on the viewing angle, or simultaneous projection of multiple independent views of a scene for multiple viewers (automultiscopic). Such multiple views can be created on the fly using the2D-plus-depthformat.

Various other display techniques have been described, such as holography,volumetric display,and thePulfrich effect,which was used inDoctor WhoDimensions in Time, in 1993, by3rd Rock From The Sunin 1997, and by the Discovery Channel'sShark Weekin 2000.

3D glasses may reduce image brightness.[25]

Producing technologies

[edit]
Modern stereo TV camera.
Main article:Stereo photography techniques

Stereoscopy is the most widely accepted method for capturing and delivering 3D video. It involves capturing stereo pairs in a two-view setup, with cameras mounted side by side and separated by the same distance as is between a person's pupils. If we imagine projecting an object point in a scene along the line-of-sight for each eye, in turn; to a flat background screen, we may describe the location of this point mathematically using simple algebra. In rectangular coordinates with the screen lying in the Y–Z plane, with the Z axis upward and the Y axis to the right, with the viewer centered along the X axis; we find that the screen coordinates are simply the sum of two terms. One accounting for perspective and the other for binocular shift. Perspective modifies the Z and Y coordinates of the object point, by a factor of D/(D–x), while binocular shift contributes an additional term (to the Y coordinate only) of s·x/(2·(D–x)), where D is the distance from the selected system origin to the viewer (right between the eyes), s is the eye separation (about 7 centimeters), and x is the true x coordinate of the object point. The binocular shift is positive for the left-eye-view and negative for the right-eye-view. For very distant object points, the eyes will be looking along essentially the same line of sight. For very near objects, the eyes may become excessively "cross-eyed". However, for scenes in the greater portion of the field of view, a realistic image is readily achieved by superposition of the left and right images (using the polarization method or synchronized shutter-lens method) provided the viewer is not too near the screen and the left and right images are correctly positioned on the screen. Digital technology has largely eliminated inaccurate superposition that was a common problem during the era of traditional stereoscopic films.[26][27]

Multi-viewcapture uses arrays of many cameras to capture a 3D scene through multiple independent video streams.Plenoptic cameras,which capture thelight fieldof a scene, can also be used to capture multiple views with a single main lens.[28]Depending on the camera setup, the resulting views can either be displayed on multi-view displays, or passed along for further image processing.

After capture, stereo or multi-view image data can be processed to extract2D plus depthinformation for each view, effectively creating a device-independent representation of the original 3D scene. These data can be used to aid inter-view image compression or to generate stereoscopic pairs for multiple different view angles and screen sizes.

2D plus depth processing can be used to recreate 3D scenes even from a single view and convert legacy film and video material to a 3D look, though a convincing effect is harder to achieve and the resulting image will likely look like a cardboard miniature.

3D production

[edit]

Productionof events such as live sports broadcasts in 3D differs from the methods used for 2D broadcasting. A high technical standard must be maintained because any mismatch in color, alignment, or focus between two cameras may destroy the 3D effect or produce discomfort in the viewer. Zoom lenses for each camera of a stereo pair must track over their full range offocal lengths.

Addition of graphical elements (such as a scoreboard, timers, or logos) to a 3D picture must place the synthesized elements at a suitable depth within the frame, so that viewers can comfortably view the added elements as well as the main picture. This requires more powerful computers to calculate the correct appearance of the graphical elements. For example, theline of scrimmagethat appears as aprojected yellow lineon the field during anAmerican footballbroadcast requires about one thousand times more processing power to produce in 3D compared to a 2D image.

Since 3D images are effectively more immersive than 2D broadcasts, fewerfast cutsbetween camera angles are needed. 3DNational Football Leaguebroadcasts cut between cameras about one-fifth as often as in 2D broadcasting. Rapid cuts between two different viewpoints can be uncomfortable for the viewer, sodirectorsmay lengthen the transition or provide images with intermediate depth between two extremes to "rest" the viewer's eyes. 3D images are most effective if the cameras are at a low angle of view, simulating presence of the viewer at the event; this can present problems with people or structures blocking the view of the event. While fewer camera locations are required, the overall number of cameras is similar to a 2D broadcast because each position needs two cameras. Other live sport events have additional factors that affect production; for example, an ice rink presents few cues for depth due to its uniform appearance.[29]

TV sets

[edit]

These TV sets were high-end and generally includedEthernet,USB player and recorder,Bluetoothand USBWi-Fi.

3D-ready TV sets

[edit]

3D-ready TV sets are those that can operate in 3D mode (in addition to regular 2D mode) using one of several display technologies to recreate astereoscopic image.These TV sets usually supportedHDMI 1.4and a minimum outputrefresh rateof 120 Hz; glasses may be sold separately.

Philipswas developing a 3D television set that would be available for the consumer market by about 2011 without the need for special glasses (autostereoscopy).[30]However it was canceled because of the slow adoption of customers going from 2D to 3D.[citation needed]

In August 2010, Toshiba announced plans to bring a range of autostereoscopic TVs to market by the end of the year.[31]

The Chinese manufacturerTCL Corporationhas developed a 42-inch (110 cm) LCD 3D TV called the TD-42F, which is currently available in China. This model uses alenticularsystem and does not require any special glasses (autostereoscopy). It currently[when?]sells for approximately $20,000.[32][33]

Onida,LG,Samsung,Sony, and Philips intended to increase their 3D TV offering with plans to make 3D TV sales account for over 50% of their respective TV distribution offering in 2012. It was expected that the screens would use a mixture of technologies until there is standardization across the industry.[34]Samsung offers the LED 7000, LCD 750, PDP 7000 TV sets and the Blu-ray 6900.[35]

Full 3D TV sets

[edit]

Full 3D TV sets includedSamsungFull HD 3D (1920×1080p, 60 Hz) andPanasonicFull HD 3D (1920×1080p, 60 Hz).[36]

A September 2011 Cnet review toutedToshiba's 55ZL2 as "the future of television". Because of the demanding nature of auto-stereoscopic 3D technology, the display features a 3840x2160 display; however, there was at the time no video content available at this resolution. That said, it utilizes amulti-core processorto provide excellent upscaling to the "4k2k" resolution. Using a directional lenticular lenslet filter, the display generates nine 3D views. This technology commonly creates dead spots, which Toshiba avoids by using an eye-tracking camera to adjust the image. The reviewers also note that the 3D resolution for a 1080p signal looks more like 720p and lacksparallax,which reduces immersion. [37]

Standardization efforts

[edit]

The entertainment industry was expected to adopt a common and compatible standard for 3D in home electronics. To present fasterframe rateinhigh definitionto avoidjudder(non-smooth, linear motion), enhancing3-D film,televisions andbroadcasting,other unresolved standards are the type of3D glasses(passive or active), includingbandwidthconsiderations,subtitles,recording format,and aBlu-raystandard. With improvements in digital technology, in the late 2000s,3D moviesbecame more practical to produce and display, putting competitive pressure behind the creation of 3D television standards. There are several techniques forStereoscopic Video Coding,and stereoscopic distribution formatting includinganaglyph,quincunx,and2D plus Delta.Serial digital interfaceis used to carry 3D TV signals within TV stations.[38][39]

Content providers, such asDisney,DreamWorks,and other Hollywood studios, and technology developers, such asPhilips,asked[when?]SMPTEfor the development of a 3DTV standard in order to avoid abattle of formatsand to guarantee consumers that they will be able to view the 3D content they purchase and to provide them with 3D home solutions for all pockets. In August 2008, SMPTE established the "3-D Home Display Formats Task Force" to define the parameters of a stereoscopic 3D mastering standard for content viewed on any fixed device in the home, no matter the delivery channel. It explored the standards that need to be set for 3D content distributed via broadcast, cable, satellite, packaged media, and the Internet to be played-out on televisions, computer screens and other tethered displays. After six months, the committee produced a report to define the issues and challenges, minimum standards, and evaluation criteria, which the Society said would serve as a working document for SMPTE 3D standards efforts to follow. A follow-on effort to draft a standard for 3D content formats was expected to take another 18 to 30 months.[citation needed]

Production studios were developing an increasing number of 3D titles for the cinema and as many as a dozen companies were actively working on the core technology behind the product.[when?]Many had technologies available to demonstrate, but no clear road forward for a mainstream offering emerged.

Under these circumstances, SMPTE's inaugural meeting was essentially a call for proposals for 3D television; more than 160 people from 80 companies signed up for this first meeting. Vendors that presented their respective technologies at the task force meeting includedSENSIO Technologies,[40]Philips,Dynamic Digital Depth (DDD),[41]TDVision,[42]andReal D,all of which had 3D distribution technologies.

There were many active 3D projects in SMPTE for both TV and filmmakers in the late 2000s. The SMPTE 35PM40 Working Group decided (without influence from the SMPTE Board or any other external influence) that the good progress being made on 3D standards within other SMPTE groups (including the IMF Interoperable Master Format) meant that its "overview" project would be best published as an Engineering Report. However, by 2011, the SMPTE board had "abandoned all further work on 3D television".[43]

However, SMPTE was not the only 3D standards group. Other organizations such as theConsumer Electronics Association(CEA),[44]3D@Home Consortium,[45]ITUand the Entertainment Technology Center (ETC),[46]atUSC School of Cinematic Artshave created their own investigation groups and have already offered to collaborate to reach a common solution. TheDigital TV Group(DTG), has committed to profiling a UK standard for 3DTV products and services. Other standard groups such asDVB,BDA,ARIB,ATSC,DVD Forum,IECand others were involved in the process.[citation needed]

MPEGhas been researching multi-view, stereoscopic, and2D plus depth3D video coding since the mid-1990s;[47]the first result of this research is theMultiview Video Codingextension forMPEG-4 AVCthat is currently undergoing standardization. MVC has been chosen by the Blu-ray disc association for 3D distribution. The format offers backwards compatibility with 2D Blu-ray players.[48]

HDMIversion 1.4, released in June 2009, defines a number of 3D transmission formats. The format "Frame Packing" (left and right image packed into one video frame with twice the normal bandwidth) is mandatory for HDMI 1.4 3D devices. All three resolutions (720p50, 720p60, and 1080p24) have to be supported by display devices, and at least one of those by playback devices. Other resolutions and formats are optional.[49]While HDMI 1.4 devices will be capable of transmitting 3D pictures in full 1080p, HDMI 1.3 does not include such support. As an out-of-spec solution for the bitrate problem, a 3D image may be displayed at a lower resolution, like interlaced or atstandard definition.

DVB 3D-TV standard

[edit]
Main article:DVB 3D-TV
See also:High-definition television

DVBhas established theDVB 3D-TVSpecification. The following 3D-TV consumer configurations will be available to the public:[50]

  • 3D-TV connected to3D Blu-rayPlayer for packaged media.
  • 3D-TV connected to HD Games Console, e.g.PS3for 3D gaming.
  • 3D-TV connected to HD STB for broadcast 3D-TV.
  • 3D-TV receiving a 3D-TV broadcast directly via a built-in tuner and decoder.

For the two broadcast scenarios above, initial requirements are forPay-TVbroadcasters to deliver 3D-TV services over existingHD broadcastinginfrastructures, and to use existing receivers (withfirmwareupgrade, as required) to deliver 3D content to 3D-TV sets, via anHDMIor equivalent connection, if needed. This is termedFrame Compatible.There are a range of Frame Compatible formats. They include the Side by Side (SbS) format, the Top and Bottom (TaB) format, and others.

On 1 January 2010, the world's first 3D channel, SKY 3D, started broadcasting nationwide inSouth Koreaby Korea Digital Satellite Broadcasting. The channel's slogan is "World No.1 3D Channel". This 24/7 channel uses the Side by Side technology at a resolution of 1920x1080i. 3D contents include education, animation, sport, documentary and performances.[61]

A full 24-hour broadcast channel was announced at the 2010 Consumer Electronics show as a joint venture from IMAX, Sony, and the Discovery channel.[62]The intent was to launch the channel in the United States by year end 2010. However, this did not materialize in time.

DirecTVand Panasonic launched 2 broadcast channels and 1Video on demandchannel with 3D content[63]in June 2010. DirecTV previewed a live demo of their 3D feed at theConsumer Electronics Showheld 7–10 January 2010.[64]

In Europe,British Sky Broadcasting(Sky) launched a limited 3D TV broadcast service on 3 April 2010. Transmitting from theAstra2Asatellite at28.2° east,Sky 3Dbroadcast a selection of live English Premier League football matches to over 1000 British pubs and clubs equipped with a Sky+HD Digibox and 3D Ready TVs, and preview programmes provided for free to top-tier Sky HD subscribers with 3D TV equipment. This was later expanded to include a selection of films, sports, and entertainment programming launched to Sky subscribers on 1 October 2010.[65]

On 28 September 2010, Virgin Media launched a 3D TV on Demand service.[66]

Several other Europeanpay-TVnetworks are also planning 3D TV channels and some have started test transmissions on otherAstrasatellites, including French pay-TV operatorCanal+which has announced its first 3D channel is to be launched in December 2010. Also the Spanish Canal+ has started the first broadcastings on 18 May 2010 and included 2010FIFA World Cupmatches in the newCanal+ 3Dchannel.[67]Satellite operatorSESstarted afree-to-air3D demonstration channel on theAstrasatellite at23.5° easton 4 May 2010 for the opening of the 2010 ANGA Cable international trade fair[68]using 3D programming supplied by 3D Ready TV manufacturer Samsung under an agreement between Astra and Samsung to co-promote 3D TV.[69]

By November 2010, there were eight 3D channels broadcasting to Europe from three Astra satellite positions, including demonstrations provided by Astra, pay-TV from BSkyB, Canal+ and others, and the Dutch Brava3D cultural channel, which provides a mix of classical music, opera and ballet free-to-air across Europe fromAstra 23.5°E.[70]

In April 2011, HIGH TV (a 3D family entertainment channel) launched. Headquartered in NY with offices in Hong Kong and London, the channel broadcasts through eight satellites round the world, covering Europe, Asia, the Nordic region, Russia, South America, Africa, Middle East and North America.

3flow is a 3D channel that began broadcasting onFreeboxin France on 1 April 2011. Made up entirely of native stereoscopic programming produced and owned by WildEarth and Sasashani (WildEarth's parent company). Initially the focus was mostly safari and has now widened to include underwater, extreme sports and other 3D content from around the world. WildEarth and Sasashani also distribute 3D series and shows through 3D Content Hub.

The channel's HD feed will be a simulcast of the standard definition feed launched in 1999, which now broadcasts to subscribers in 66 territories and in 12 languages across Europe, the Middle East and Africa (EMEA). The inaugural launch on Italy's Sky platform sees the channel's entrance into the HD market and from there it will begin rolling out to operators across the EMEA region.

In February 2012 Telecable de Tricom, a major Dominican cable TV provider, announced the launch of the first 3D TV programming package in Latin America. As of 3 July 2012, the only 3D channels available are 3flow and HIGH TV 3D.[73]

In July 2013 the BBC announced that it would be indefinitely suspending 3D programming due to a lack of uptake. Only half of the estimated 1.5 million households in the UK with a 3D-enabled television watched the 2012 summer's Olympics opening ceremony in 3D.[74]

In 2013, in the US,ESPN 3Dwas shut down due to lack of demand, followed byXfinity 3Dand allDirecTV3D programming in 2014.

3D episodes and shows

[edit]

There have been several notable examples in television where 3D episodes have been produced, typically as one-hour specials or special events.

1980s

[edit]

The first-ever 3D broadcast in the UK was an episode of the weekly science magazineThe Real World,made byTelevision Southand screened in the UK in February 1982. The program included excerpts of test footage shot byPhilipsin the Netherlands. Red/green 3D glasses were given away free with copies of theTV Timeslistings magazine, but the 3D sections of the program were shown in monochrome. The experiment was repeated nationally in December 1982, with red/blue glasses allowing color 3D to be shown for the first time. The program was repeated the following weekend followed by a rare screening of theWesternFort TistarringGeorge MontgomeryandJoan Vohs.

In 1985 Portugal's national TV channelRTP 1broadcast the movieCreature from the Black Lagoonin anaglyph format. Red/cyan 3D glasses were sold with magazines.[77][78]

1990s

[edit]

In November 1993, theBBCannounced a one-off week of 3D programming filmed using the pioneeringPulfrich 3Dtechnique. 3D glasses were sold in shops around the UK, a percentage of the sales going to theChildren In Needcharity. The week's programming concluded with a screening of the 3DDoctor Whospecial "Dimensions In Time"as well as specially shot segments ofNoel's House Partyand the annualChildren In Needcharity appeal.

3D television episodes were a brieffadon U.S. television during the May 1997 sweeps. The sitcom3rd Rock from the Sunshowed a two-part episode, "Nightmare On Dick Street",where several of the characters' dreams are shown in 3D. The episode cued its viewers to put on their 3D glasses (which used thePulfrich effect) by including "3D on" and "3D off" icons in the corner of the screen as a way to alert them as to when the 3D sequences would start and finish. Customers were given free glasses courtesy of a joint venture betweenLittle Caesarspizza andBarq'sRoot Beer. Also in May 1997, ABC had a special line-up of shows that showcased specific scenes in 3D. The shows includedHome Improvement,Spin City,The Drew Carey Show,Ellen,Family Matters,Step by Step,Sabrina, The Teenage Witch,andAmerica's Funniest Home Videos.Similar to3rd Rock,an icon alerted viewers when to put on the 3D glasses. Customers were given free anaglyph glasses atWendy'sfor the promotion. Nickelodeon had a special lineup of shows in 1997 that also showcased specific scenes in 3D promoted as Nogglevision; ChromaDepth was the technology of choice for Nickelodeon's 3D.

2000s

[edit]

Television shows including the dramaMediumand the comedyChuck(Season 2, episode 12) used 3D television.

Channel 4in the UK ran a short season of 3D programming in November 2009 including Derren Brown and The Queen in 3D. Unlike previous British 3D TV experiments, the program were transmitted inColorCode 3D.[79]

In May 2006 Portugal's national TV channelRTP 1broadcast several shows in anaglyph format ( "Real 3D" ) for a week. Red/cyan 3D glasses were sold exclusively by a hypermarket chain.[77]

2010s

[edit]

Decline

[edit]

As early as 2013, 3D televisions were being seen as a fad.[97][98]DirecTVhad stopped broadcasting 3D programs in 2012, while ESPN stopped in 2013.[99]In the UK, Sky moved its content to on-demand, and the BBC ended airing 3D shows in 2013 due to "lack of public appetite".[100][101]

Fewer and fewer 3D TVs were sold and soon TV manufacturers stopped making them. Vizio stopped production in 2014 and was followed by others.[102]In January 2017, the last two major television manufacturers still producing 3D televisions, Sony and LG, announced they would stop all 3D support.[99]

World record

[edit]

The screen made it toThe Guinness Book of World Recordsas the world's biggest screen.[103][104]The live 3D broadcast was provided by the companyViasat.[105]

Health effects

[edit]

Some viewers have complained ofheadaches,seizuresandeyestrainafter watching Active Shutter 3DTV.[106][107]There have been several warnings, especially for the elderly.[108]Motion sickness,in addition to other health concerns,[109]is more easily induced by 3D presentations.

There are primarily two effects of 3D TV that are unnatural for the human vision: crosstalk between the eyes caused by imperfect image separation and the mismatch betweenconvergenceandaccommodationcaused by the difference between an object's perceived position in front of or behind the screen and the real origin of that light on the screen.[110]

It is believed that approximately 12% of people are unable to properly see 3D images, owing to a variety of medical conditions.[111][112]According to another experiment, up to 30% of people have very weak stereoscopic vision preventing depth perception based on stereo disparity. This nullifies or greatly decreases immersion effects of digital stereo to them.[113]
