An LCD television set with a 16:9 image ratio.

16:9 (1.77:1) (16:9 = 42:32) is an aspect ratio with a width of 16 units and height of 9. Since 2009, it has become the most common aspect ratio for sold televisions and computer monitors and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen television.

History

File:Dr. Kerns Powers, SMPTE derivation of 16-9 aspect ratio.svg
An equal-area comparison of the aspect ratios which Dr. Kerns Powers employed to derive the SMPTE 16:9 standard.[1] TV 4:3/1.33 in red, 5:3/1.66 in orange, 16:9/1.77 in blue, 1.85 in yellow, Panavision 11:5/2.2 in mauve and CinemaScope/2.35 in purple.

Dr. Kerns H. Powers, a member of the SMPTE Working Group on High-Definition Electronic Production, first proposed the 16:9 (1.77:1) aspect ratio at a time when nobody was creating 16:9 videos. The popular choices in 1980 were: 1.33:1 (based on television standard's ratio at the time), 1.66:1 (the European "flat" ratio), 1.85:1 (the American "flat" ratio), 2.20:1 (the ratio of 70 mm films and Panavision) and 2.39:1 (the CinemaScope ratio for anamorphic widescreen films).

Powers cut out rectangles with equal areas, shaped to match each of the popular aspect ratios. When overlapped with their center points aligned, he found that all of those aspect ratio rectangles fit within an outer rectangle with an aspect ratio of 1.77:1 and all of them also covered a smaller common inner rectangle with the same aspect ratio 1.77:1.[1] The value found by Powers is exactly the geometric mean of the extreme aspect ratios, 4:3 (1.33:1) and 2.35:1, which is coincidentally close to 16:9 (1.77:1). Applying the same geometric mean technique to 16:9 and 4:3 yields the 14:9 aspect ratio, which is likewise used as a compromise between these ratios.[2]

While 16:9 (1.77:1) was initially selected as a compromise format, the subsequent popularity of HDTV broadcast has solidified 16:9 as perhaps the most important video aspect ratio in use.[citation needed] Most 4:3 (1.33:1) and 2.39:1 video is now recorded using a "shoot and protect" technique[3] that keeps the main action within a 16:9 (1.77:1) inner rectangle to facilitate HD broadcast[citation needed]. Conversely it is quite common to use a technique known as center-cutting, to approach the challenge of presenting material shot (typically 16:9) to both a HD and legacy 4:3 audience simultaneously without having to compromise image size for either audience. Content creators frame critical content or graphics to fit within the 1.33 raster space.[citation needed] This has similarities to a filming technique called Open matte.

After the original 16:9 Action Plan of the early 1990s, the European Union has instituted the 16:9 Action Plan,[4] just to accelerate the development of the advanced television services in 16:9 aspect ratio, both in PAL and also in HDTV. The Community fund for the 16:9 Action Plan amounted to 228 million.

In 2008 the computer industry started switching to 16:9 as the standard aspect ratio for monitors and laptops. A 2008 report by DisplaySearch cited a number of reasons for this shift, including the ability for PC and monitor manufacturers to expand their product ranges by offering products with wider screens and higher resolutions, helping consumers to more easily adopt such products and "stimulating the growth of the notebook PC and LCD monitor market".[5]

In 2011 Bennie Budler, product manager of IT products at Samsung South Africa, confirmed that monitors capable of 1920×1200 resolutions aren't being manufactured anymore. “It is all about reducing manufacturing costs. The new 16:9 aspect ratio panels are more cost effective to manufacture locally than the previous 16:10 panels”.[6] Since computer displays are advertised by their diagonal measure, for monitors with the same display area, a wide screen monitor will have a larger diagonal measure, thus sounding more impressive. Within limits, the amount of information that can be displayed, and the cost of the monitor depend more on area than on diagonal measure.

In March 2011 the 16:9 resolution 1920×1080 became the most common used resolution among Steam's users. The earlier most common resolution was 1680×1050 (16:10).[7]

Properties

16:9 is the only widescreen aspect ratio natively supported by the DVD format. Anamorphic DVD transfers store the information as 5:4 (PAL) or 3:2 (NTSC) square pixels, which is set to expand to either 16:9 or 4:3, which the television or video player handles. For example, a PAL DVD with a full frame image may contain a video resolution of 720×576 (5:4 ratio), but a video player software will stretch this to 1024×576 square pixels with a 16:9 flag in order to recreate the correct aspect ratio.

DVD producers can also choose to show even wider ratios such as 1.85:1 and 2.39:1[a] within the 16:9 DVD frame by hard matting or adding black bars within the image itself. Some films which were made in a 1.85:1 aspect ratio, such as the U.S.-Italian co-production Man of La Mancha and Kenneth Branagh's Much Ado About Nothing, fit quite comfortably onto a 1.77:1 HDTV screen and have been issued anamorphically enhanced on DVD without the black bars. Many digital video cameras have the capability to record in 16:9.

Super 16 mm film is frequently used for television production due to its lower cost, lack of need for soundtrack space on the film itself, and aspect ratio similar to 16:9.[citation needed]

In Europe

In Europe, 16:9 is the standard broadcast format for most digital channels and all HDTV broadcasts. Some countries adopted the format for analog television, first by using the PALplus standard (now obsolete) and then by simply using WSS signals on normal PAL broadcasts.

23x15px Spain As of 2013, all nationalwide and regional channels on 16:9, as the national standard for television. Practically all of the local tv channels in 16:9. 4:3 is still common in PPV channels. Older programmes filmed in 4:3 are transmitted in their original format or zooming to 14:9 Pillarbox; stretched programs are rare.

The first films were broadcast in 16:9 (PALplus) at TV3 and TVG in 1997. Transition to widescreen programs and commercials started in only DVB-T and regional channels like Neox, Nova, Teledeporte, TV3 (Catalonia) or Aragón Televisión in late 2008, and in main analog networks in 2009 (except TVE). HD versions of nationwide main TV channels, Antena 3, Telecinco, LaSexta and TVE (as TVE HD) were launched (or relaunched in the case of TVE-HD) in 2010. 1080i HD version of Cuatro was launched in 2012. Main news programme in Spain, Telediario, only available in 16:9 as late as January 2012. Other networks' news programmes adapted to 16:9 in 2009 or early 2010.

23x15px United Kingdom In 1998, with the introduction of digital television, digital versions of BBC One, BBC Two, ITV and Channel 4 were created. An On Digital set top box or a subscription to Sky Digital was required to view the digital versions.

On 1 July 2000, "C-Day", most of the UK broadcast industry began requiring commercials to be delivered in 16:9 full-height format (with a 14:9 safe area for those channels still broadcasting in 4:3). ITV and C4 upgraded their continuity suites to be 16:9 capable at the same time, allowing idents to be broadcast in widescreen format on digital.
In 2001, the UK's fourth broadcaster Channel 5 switched to 16:9.
In 2002, On Digital became defunct and free-to-air digital terrestrial television services instead began to operate under the name of Freeview.
In 2003, Sky branded channels were re-branded which included the switch to 16:9.
In 2006, BBC HD began broadcasting in 1080i which became the standard for all HD channels. Similar to the switch to Digital in 1998, viewers using terrestrial services required an additional set-top-box which was HD capable
In 2007, Channel 4 HD was launched on Sky. It was later added to Virgin Media in 2009 and then to Freeview HD in 2011.
In 2008, ITV HD was launched on Freesat and was later added to Virgin Media, Sky and Freeview HD in 2010.
In 2009, Freeview HD launched allowing terrestrial viewers to watch BBC HD and ITV HD without a subscription, a Freeview HD set-top box or television is required.
In 2010, Channel 5 HD was launched on Sky and Virgin Media.
In 2011, BBC One HD was launched on Sky, Virgin Media and Freeview HD.

As of 2012,
Almost all Freeview channels broadcast in 16:9;
Almost all Virgin Media/Sky channels broadcast in 16:9 with the rest expected to switch by the end of 2012.
