Keeping Kids In Mind

Televisions capable of displaying UHD resolutions are seen by consumer electronics companies as the next trigger for an upgrade cycle after a lack of consumer interest in 3D television. Find 4k wallpaper stock images in HD and millions of other royalty-free stock photos, illustrations and vectors in the Shutterstock collection. This higher bit rate reduces the visibility of ugly compression artefacts, even if viewed on monitors with a lower resolution than 2160p. • Too many images selected.

Some articles claim that the terms "2K" and "4K" were coined by DCI and refer exclusively to the 2K and 4K formats defined in the DCI standard. [99], In February 2016, Univision trialed 4K by producing a closed circuit telecast of a football friendly between the national teams of Mexico and Senegal from Miami in the format.

Select from premium 4k Resolution of the highest quality. [126][127][128], Many consumer electronics such as mobile phones store video footage with 4:2:0 chroma subsampling, which means that color information is stored at only a quarter of the resolution as the brightness information. [61] The resolution was targeted at the bit-mapped desktop publishing market. [66] In November 2013, YouTube began to use the VP9 video compression standard, saying that it was more suitable for 4K than High Efficiency Video Coding (HEVC). Most of the new M+ technology was employed on 4K TV sets which led to a controversy after tests showed that the addition of a white sub pixel replacing the traditional RGB structure would reduce the resolution by around 25%.

[20] CEA defines an Ultra HD product as a TV, monitor, or projector with the following characteristics:[21]. [100][101][102] In March 2016, DirecTV and CBS Sports announced that they would produce the "Amen Corner" supplemental coverage from the Masters golf tournament in 4K. [123] Increased fineness and contrast is then possible with output to DVD and Blu-ray. © 2020 Getty Images. 4K video comes to YouTube", "Next-Gen Video Format H.265 Is Approved, Paving The Way For High-Quality Video On Low-Bandwidth Networks", "Naughty America: 4K porn is coming, trailer released", "Payserve Launches 4k Ultra-HD Site, Sindrive". In the year 2014, the OnePlus One was released with the option to record DCi 4K (4096 × 2160) at 24 frames per second. It is sometimes referred to as "2160p", based on the naming patterns established by the previous 720p and 1080p HDTV standards. {{familyColorButtonText(colorFamily.name)}}, View {{carousel.total_number_of_results}} results. Select 100 images or less to download. As noted above, DCI 4K is 4096 × 2160, while 4K UHD is 3840 × 2160, producing a slight difference in aspect ratio rather than a significant difference in resolution. Thousands of new, high-quality pictures added every day. [56][57], High Efficiency Video Coding (H.265) should allow streaming 4K content with a bandwidth of 20 to 30 Mbit/s. [81] Critics state that at normal direct-view panel size and viewing distances, the extra pixels of 4K are redundant at the ability of normal human vision. [1] Digital television and digital cinematography commonly use several different 4K resolutions. In 1984, Hitachi released the CMOS graphics processor ARTC HD63484, which was capable of displaying up to 4K resolution when in monochrome mode. Two production units were used, producing the traditional broadcast in high-definition, and a separate 4K broadcast. [65] Users could view 4K video by selecting "Original" from the quality settings until December 2013, when the 2160p option appeared in the quality menu. These standards use resolutions of 3840 × 2160 and 7680 × 4320 respectively, with framerates of up to 60 Hz, color depth up to 10 bpc (30 bit/px), and HEVC encoding for transmission. 720p / 1080p), This page was last edited on 23 October 2020, at 16:52.

[67] Sony was offering 4K projectors as early as 2004. Pixel shifting, as described here, was pioneered in the consumer space by JVC, and later in the commercial space by Epson. Although 3840 × 2160 is both a 4K resolution and a 2160p resolution, these terms cannot always be used interchangeably since not all 4K resolutions are 2160 pixels tall, and not all 2160p resolutions are ≈4000 pixels wide. [14][15] The standard defines the following characteristics for these systems: In 2012, the International Telecommunication Union, Radiocommunication Sector published Recommendation ITU-R BT.2020, also known as the Ultra High Definition Television (UHDTV) standard. [5](p9) Since the resolution in CEA's definition is only a minimum requirement, displays with higher resolutions such as 4096 × 2160 or 5120 × 2880 also qualify as "Ultra HD" displays, provided they meet the other requirements. [124] Some cinematographers record at 4K with the Super 35 film format to offset any resolution loss that may occur during video processing. MSI GS70 Stealth - top. In television and consumer media, 3840 × 2160 (4K UHD) is the dominant 4K standard, whereas the movie projection industry uses 4096 × 2160 (DCI 4K).
In other words, pixel shifting cannot produce adjacent vertical lines of RGBRGB or other colors where each line is one pixel (1/3840th of the screen) wide. This is why "true" 4K projectors cost so much more than 4K UHD projectors with otherwise similar feature sets. In the years 2017 and 2018, mobile phone chipsets have reached sufficient processing power that mobile phone vendors started releasing mobile phones that allow recording 2160p footage at 60 frames per second for a smoother and more realistic appearance. [39] On April 11, 2013, Bulb TV created by Canadian serial entrepreneur Evan Kosiner became the first broadcaster to provide a 4K linear channel and VOD content to cable and satellite companies in North America. The term "2160p" could be applied to any format with a height of 2160 pixels, but it is most commonly used in reference to the 4K UHDTV resolution of 3840 × 2160 due to its association with the well-known 720p and 1080p HDTV formats.

[82] This technology of non-native 4K entered its fourth generation for 2016. [58], In January 2014, Naughty America launched the first adult video service streaming in 4K.[59][60]. In 2005, Digital Cinema Initiatives (DCI), a prominent standards organization in the cinema industry, published the Digital Cinema System Specification. [83][84][85] JVC used this same technology to provide 8K flight simulation for Boeing that met the limits of 20/25 visual acuity.[86]. This is the resolution of the UHDTV1 format defined in SMPTE ST 2036-1,[15] as well as the 4K UHDTV format defined by ITU-R in Rec.
