10K Resolution
10K resolution refers to a horizontal display resolutions of approximately 10,000 pixels. Unlike 4K UHD and 8K UHD, there are no 10K resolutions defined in the UHDTV broadcast standard. The first 10K displays demonstrated were ultrawide "21:9" screens with a resolution of , the same vertical resolution as 8K UHD. History On June 5, 2015, Chinese manufacturer BOE showed a 10K display with an aspect ratio of 64:27 (≈21:9) and a resolution of . In November 2016, the Consumer Technology Association published CTA-861-G, an update to their standard for digital video transmission formats. This revision added support for 102404320, a 10K resolution with an aspect ratio of 64:27 (≈21:9), at up to 120Hz. On January 4, 2017, HDMI version 2.1 was officially announced, and was later released on November 28, 2017. HDMI 2.1 includes support for all the formats listed in the CTA-861-G standard, including 10K (102404320) at up to 120Hz. HDMI 2.1 specifies a new Ultra High Speed HDMI cable ...

Display Resolution
The display resolution or display modes of a digital television, computer monitor, or other display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode-ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays. It is usually quoted as ', with the units in pixels: for example, ' means the width is 1024 pixels and the height is 768 pixels. This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight". One use of the term ''display resolution'' applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, AMOLED, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pi ...

Television Technology
The technology of television has evolved since its early days using a mechanical system invented by Paul Gottlieb Nipkow in 1884. Every television system works on the scanning principle first implemented in the rotating disk scanner of Nipkow. This turns a two-dimensional image into a time series of signals that represent the brightness and color of each resolvable element of the picture. By repeating a two-dimensional image quickly enough, the impression of motion can be transmitted as well. For the receiving apparatus to reconstruct the image, synchronization information is included in the signal to allow proper placement of each line within the image and to identify when a complete image has been transmitted and a new image is to follow. While mechanically scanned systems were experimentally used, television as a mass medium was made practical by the development of electronic camera tubes and displays. By the turn of the 21st century, it was technically feasible to replace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultrawide Formats
Ultrawide formats refers to photos, videos, and displays with Aspect ratio (image), aspect ratios greater than 2. There were multiple moves in history towards wider formats, including one by Disney,p20, Sherlock, Daniel J"Wide Screen Movies" Corrections 1994–2004 with some of them being more successful than others. Cameras usually capture ultra-wide photos and videos using an anamorphic format lens, which shrinks the extended horizontal Field of view, field-of-view (FOV) while saving on film or disk. Historic Ultrawide Cinema Historically ultrawide movie formats have varied between ~2.35 (1678:715), ~2.39 (1024:429) and 2.4. To complicate matters further, films were also produced in following ratios: 2.55, 2.76 and 4. Developed by Rowe E. Carney Jr. and Tom F. Smith, the Smith-Carney System used a 3 camera system, with 4.6 (1737:370) ratio, to project movies in 180°. Disney even created a 6.85 ratio, using 5 projectors to display 200°. The only movie filmed in Disney's 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hasselblad
Victor Hasselblad AB is a Sweden, Swedish manufacturer of medium format (film), medium format cameras, photographic equipment and image scanners based in Gothenburg, Sweden. The company originally became known for its classic analog medium-format cameras that used a waist-level viewfinder. Perhaps the most famous use of the Hasselblad camera was during the Apollo program missions when the first humans Moon landing, landed on the Moon.

Chroma Subsampling
Chroma subsampling is the practice of encoding images by implementing less resolution for Chrominance, chroma information than for luma (video), luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance. It is used in many video and still image encoding schemesboth analog and digitalincluding in JPEG encoding. Rationale Digital signals are often compressed to reduce file size and save transmission time. Since the human visual system is much more sensitive to variations in brightness than color, a video system can be optimized by devoting more bandwidth to the luma (video), luma component (usually denoted Y'), than to the color difference components Cb and Cr. In compressed images, for example, the 4:2:2 Y'CbCr scheme requires two-thirds the bandwidth of non-subsampled "4:4:4" R'G'B'. This reduction results in almost no visual difference as perceived by the viewer. How subsampling works The Visual perception, human vi ...

4K Resolution
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 38402160 (4K UHD) with a 16:9 aspect ratio is the dominant standard, whereas the digital cinema, movie projection industry uses 40962160 (Digital Cinema Initiatives, DCI 4K). The 4K television market share increased as prices fell dramatically throughout 2013 and 2014. 4K standards and terminology The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. Several different 4K resolutions have been standardized by various organizations. The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p" (''cf.'' "1080p"). While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3 ...

Display Stream Compression
Display Stream Compression (DSC) is a VESA-developed video compression algorithm designed to enable increased display resolutions and frame rates over existing physical interfaces, and make devices smaller and lighter, with longer battery life. It is a low-latency algorithm based on delta PCM coding and YCC-R color space. Effect Although DSC is not mathematically lossless, it meets the ISO/IEC 29170 standard for " visually lossless" compression, a form of compression in which "the user cannot tell the difference between a compressed and uncompressed image". ISO 29170 more specifically defines an algorithm as visually lossless "when all the observers fail to correctly identify the reference image more than 75% of the trials". However, the standard allows for images that "exhibit particularly strong artifacts" to be disregarded or excluded from testing, such as engineered test images. Research of DSC using the ISO/IEC 29170 interleaved protocol, in which an uncompressed refere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data-rate Units
In telecommunications, data transfer rate is the average number of bits ( bitrate), characters or symbols ( baudrate), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s). For example, the data rates of modern residential high-speed Internet connections are commonly expressed in megabits per second (Mbit/s). Standards for unit symbols and prefixes Unit symbol The ISQ symbols for the bit and byte are ''bit'' and ''B'', respectively. In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet. The abbreviation bps is often used to mean bit/s, so that when a ''1 Mbps'' connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s ( megabyte per second), or about 0.1192 MiB/s ( mebibyte per second). ...
