What is 2160p Continue The standard resolution of 4K video size refers to the horizontal resolution of the display of about 4000 pixels. Digital TV and digital cinema typically use several different 4K resolutions. in television and consumer media, 3840 × 2160 (4K UHD) is the dominant 4K standard, while the film projection industry uses 4096 × 2160 (DCI 4K). The share of the 4K television market increased as prices plummeted during 2014 and 2015. By 2020, more than half of U.S. households are expected to have 4K TVs, which is much faster than Full HD (1080p). Comparison of general broadcasting permissions Comparison of general 4K display permissions and the terminology of the term 4K is common and applies to any resolution with a horizontal pixel count of about 4000. (p2) Various organizations have standardized several different resolutions 4K. DCI Digital Cinema System Specification Comparison of DCI and UHD Resolutions In 2005, the Digital Film Initiatives (DCI), a prominent standards organization in the film industry, published the specifications of the digital film system. This specification establishes standardized 2K and 4K container formats for digital film production, with resolutions of 2048 × 1080 and 4096 × 2160 respectively. (4.3.1 euros) The video content resolution inside complies with the SMPTE 428-1 standard, which sets the following resolutions for the distribution of 4K ×: 256∶135 or ≈1.90∶1 side ratio) 3996 × 2160 (flat culture, flat culture, 1.85∶1 side ratio) 4096 × 1716 (Culture CinemaScope, ≈2.39∶1 side ratio) 2K distributions can have a frame rate of 24 or 48 FPS, while 4K distributions must have a frame rate of 24 FPS. (3,1,4,2 euros) Some articles state that the terms 2K and 4K were coined by DCI and relate exclusively to the 2K and 4K formats defined in the DCI standard. However, the use of these terms in the film industry preceded the publication of the DCI standard, and they are generally understood as random terms for any resolution of approximately 2,000 or 4,000 pixels wide rather than names for specific permissions. In 2007, the Society of Film and Television Engineers published SMPTE ST 2036-1, which defines parameters for two UHDTV systems called UHDTV1 and UHDTV2. The standard identifies the following characteristics for these systems: Resolution 3840 × 2160 (UHDTV1) or 7680 × 4320∶ (UHDTV2) for the overall image aspect ratio of 16∶9 (5.1) frame rate 23,976, 24, 25, 29.97, 30, 50, 59.94, 60, 100, 119.88, or 120 Hz with progressive scanning (1,2) RGB, Y'CBCR 4:4:4, 4:4 2:2, or 4:2:0 Pixel coding (7.7) 10 bpc (30 bits/px) or 12 bpc (36 bits/px) color Characteristics of coloration defined in the standard, including color primaries, quantitative parameters and electro-optomic function. The same characteristics were later standardized in ITU-R BT.2020. UHDTV1 systems are allowed to use BT.709 colored primaries up to 60 Hz. It takes the same image settings as defined in SMPTE ST 2036-1. Although UHDTV does not identify any official names for the formats it defines, ITU typically uses the terms 4K, 4K UHD or 4K UHDTV to refer to system 3840 × 2160 in public announcements and press releases (8K for 7680 × 4320). In some other ITU standards, the terms UHDTV1 and UHDTV2 are used as abbreviated documents. CEA Ultra HD In October 2012, the Consumer Electronics Association (CEA) announced its definition of ultra High-Definition (or Ultra HD) for use with consumer display marketing devices. CEA defines Ultra HD as a TV monitor, or projector with the following characteristics: resolution 3840 × 2160 or more Side ratio of 1.77∶1 (16∶9) or broader color support 8 bpc (24 bits/px) or above At least one HDMI input capable of supporting 3840 × 2160 in 24, 30, 30 and 60 Hz progressive scanning (although not necessarily with RGB/Y'CBCR 4:4:4 color), and HDCP 2.2 are able to process images according to the color scheme defined in ITU-R BT.709 Capable of re-dusting HD content (i.e. 720p/1080p) THE CEA definition allows manufacturers to use other terms such as 4K-along with the Ultra HD logo. Since the resolution in the CEA definition is only a minimum requirement, higher-resolution displays such as 4096 × 2160 or 5120 × 2880 also qualify as Ultra HD displays, provided they meet other requirements. Resolution 2160p Some 4K resolutions, such as 3840 × 2160, are often accidentally referred to as 2160p. which refer to the format by number of pixels/lines along the vertical axis (e.g. 1080p for 1920 × 1080 progressive scanning, or 480i for 480-line intertwined SDTV formats) rather than horizontal pixels (≈4000 or 4K for 3840 × 2160). The term 2160p can be applied to any format with a height of 2160 pixels, but it is most commonly used in connection with the resolution of 4K UHDTV 3840 × 2160 because of its connection with the known formats 720p and 1080p HDTV. Although the 3840 × 2160 is both a 4K resolution and a 2160p resolution, these terms cannot always be used interchangeably Not all 4K resolutions are 2,160 pixels high, and not all 2160p resolution ≈4000 pixels wide. However, some companies have started using the term 4K to describe 2160p resolution-enabled devices, even if it's not close to 4,000 pixels wide. For example, many 4K dash cams only support resolution 2880 × 2160 (4∶3); ∶ × Although it's a 2160p resolution, it's not a 4K resolution. In 2015, LG Display announced the introduction of a new technology called M, which is the addition of a white subpixel along with conventional RGB points in their IPS panel technology. Smee and Internet users later called these TVs RGBW because of the white sub-pixel. Much of the new MOH technology was used on 4K TVs, leading to controversy after tests showed that adding white sub-pixels replacing the traditional RGB structure would reduce resolution by about 25%. After tests conducted by Intertek, which analyzed the technical aspects of LG M TVs, and they concluded that the address display resolution is 2880 X 2160 for each red, green, blue, in other words, LG TVs were technically 2.8K, as it became known in the controversy. Although LG Display has developed this technology for use in laptop display, outdoors and smartphones, it is more popular in the television market due to the intended 4K UHD resolution on the market, but is still unable to achieve the true resolution of the 4K UHD, defined by the CTA as 3840x2160 active pixels with 8-bit color. This negatively affects text visualization, making it a little more fluffy, which is especially noticeable when the TV is used as a PC monitor. Adoption of YouTube and the television industry was adopted by 3840 × 2160 as a 4K standard. On April 11, 2013, Bulb TV, created by Canadian serial entrepreneur Evan Kosiner, became the first broadcaster to provide 4K linear channel and VOD content to cable and satellite companies in North America. The channel is licensed by the Canadian Radio Television and Telecommunications Commission to provide educational content. However, 4K content is becoming more available online, including on Apple TV, YouTube, Netflix and Amazon. By 2013, some UHDTV models were available to general consumers in the US$600 range. As the 2015 update, prices for small computer and television panels fell below $400. In 2014, the Digital Video Broadcasting Project released a new set of standards designed to guide high-resolution content on television. Dubbed DVB-UHDTV, it installs two two uhD-1 (for 4K content) and UHD-2 (for 8K content). These standards use 3840 × 2160 and 7680 × 4320 respectively, with frame rates of up to 60 Hz, color depth of up to 10 bpc (30 bpx) and HEVC coding for transmission. The DVB is currently focusing on the introduction of uhD-1. DVB completed the second phase of UHD-1 in 2016, and the introduction of the service by broadcasters is expected in 2017. THE UHD-1 Phase 2 adds features such as high dynamic range (using HLG and HF at 10 or 12 bits), wide color range (BT. 2020/2100 color), and high frame rate (up to 120 Hz). Streaming YouTube videos dating back to 2010, and Vimeo allow a maximum download resolution of 4096 × 3072 pixels (12.6 megapixels, a side ratio of 4:3). Vimeo's 4K content is currently limited mainly to nature documentaries and technical coverage. High-essential video coding (H.265) should allow 4K streaming content with a bandwidth of 20 to 30 Mbps. Naughty America has launched the first adult video service, streaming in 4K×. In 2014, the OnePlus One was released with the ability to record DCi 4K (4096 × 2160) with 24 frames per second. In 2017 and 2018, mobile phone chipsets achieved enough computing power that mobile phone manufacturers have started releasing mobile phones that allow recording 2,160p of footage at 60 frames per second for smoother and more realistic looks. The story of Samsung UN105S9 105-inch (2700 mm) ultra-high-definition 4K TV In 1984 Hitachi released a graphics processor CMOS ARTC HD63484, which was able to display up to 4K resolution when in monochrome mode. The resolution was focused on the bit-map of the desktop publishing market. The first commercially available 4K camera for cinematic purposes was Dalsa Origin, released in 2003. 4K technology has been developed by several research groups at universities around the world, such as the University of California, San Diego, CALIT2, Keio University, Naval Graduate School and others, which have implemented several demonstrations in places like IGrid in 2004 and CineGrid.
