The results of this experiment yielded the consensus that the horizontal resolution of around pixels was required to replace films, and JPEG was suitable for the compression of digital cinema data. Stimulated by the experiment, DCI accelerated the standardization of digital cinema, specified the movie format of pixels, and simply called it 8K.
DCI finalized version 1.
To explore the application range of 8K video beyond digital cinema, we developed a JPEGbased 8K real time streaming codec system.
The following sections describe the features of the 8K imaging systems used in digital cinema and live streaming.
It has following advantages: 1. Higher image definition quality. More detailed picture.
Better fast-action. Larger projection surface visibility. Meanwhile, standard p and p resolutions were named because of its vertical resolution.
The new standard renders more than four times higher image definition than p resolutions for example. For example is a frame size with aspect and - The digital video resolutions examples: Pixel Densities of 8K.
YouTube enabled 8K video support in the middle of This paper introduces successive research on SHD image transmission and its application, especially in digital cinema and associated application fields. This decoder was designed to realize IP transmission of extra-high-quality videos, while fully utilizing the full bandwidth of emerging commercial communication networks based on 1-Gb Ethernet.
In , the second prototype SHD image decoder was developed that exploits a highly parallel processing unit of JPEG de-compressors.
The decoder receives the IP streams of compressed video contents transmitted by a video server over a 1-GbE network, and decodes them using the standard JPEG decoding algorithm in real time. The decoder was combined with a special pixel projector using a dedicated digital video interface for the decoder. This architecture allows the decoded videos to be transferred and shown in completely digital form.
This system triggered detailed discussions on the digital cinema video format for DCI.
The question was whether a higher image quality than HDTV was required to replace movie films. The results of this experiment yielded the consensus that the horizontal resolution of around pixels was required to replace films, and JPEG was suitable for the compression of digital cinema data. Stimulated by the experiment, DCI accelerated the standardization of digital cinema, specified the movie format of pixels, and simply called it 8K.

The term "display resolution" is usually used to mean pixel dimensions, the number of pixels in each dimension e. In digital measurement, the display resolution would be given in pixels per inch. In analog measurement, if the screen is 10 inches high, then the horizontal resolution is measured across a square 10 inches wide.
This is typically stated as "lines horizontal resolution, per picture height;" for example, analog NTSC TVs can typically display about lines of "per picture height" horizontal resolution from over-the-air sources, which is equivalent to about total lines of actual picture information from left edge to right edge.
While there is no standardized meaning for high-definition, generally any video image with more than horizontal lines North America or lines Europe is considered high-definition.
Images of standard resolution captured at rates faster than normal by a high-speed camera may be considered high-definition in some contexts. Television series' shot on high-definition video are made to look as if they have been shot on film, a technique which is often known as filmizing. The video-to-film conversion process consists of two major steps: first, the conversion of video into digital "film frames" which are then stored on a computer or on HD videotape; and secondly, the printing of these digital "film frames" onto actual film.
To understand these two steps, it is important to understand how video and film differ. Film has remained unchanged for almost a century and creates the illusion of moving images through the rapid projection of still images, "frames", upon a screen, typically 24 per second. Traditional interlaced SD video has no real frame rate, though the term "frame" is applied to video, it has a different meaning. Instead, video consists of a very fast succession of horizontal lines that continually cascade down the television screen streaming top to bottom, before jumping back to the top and then streaming down to the bottom again, repeatedly, almost 60 alternating screen fulls every second for NTSC, or exactly 50 such screen fulls per second for PAL and SECAM.
Since visual movement in video is infused in this continuous cascade of scans lines, there is no discrete image or real "frame" that can be identified at any one time.
