About 8K Resolution/Display Video and UHDTV

Maybe most of you are still curious and yearning for 4K video and TV, taking no notice of 8K resolution video or TV, YouTube has already been expericing its support for 8K resolution 
video like dubbed Ghost Towns at early June, 2015, which was shot by a RED Epic Dragon 6K camera and then stitched by Adobe After Effects or directly upscaled to 8K resolution from 6K. This 8K video viewing is quite astonishing on computer built in high-level hardware, but "horrible" on 8K unfriendly ones.
This article will give you a specific definition of what is 8K and list you the 8K history and future, pros and cons of 8K resolution video and TV.
8K resolution (7680 x 4320, 4320p), the successor of 4K resolution, is now the highest 
UHDTV (ultra high definition television) resolution in digital television and film restoration/mastering and is 16 times detailed than current 1080p resolution. 4K is speculated
 to become a mainstream standard in televisions by 2017 and NHK plans to apply 8K to Japan TV broadcasting in 2020, especially in the 2020 Tokyo Olympics.

History and Future of 8K Resolution UHDTV & Video

Developed by NHK in 1995, and 17 years later in 2012, taken as the standard of Super 
Hi-Vision (SHV) by the International Telecom Union of United Nations took 8K resolution 
(7,680 x 4,320), and promoted by NHK, BBC and RAI together, 8K resolution grow rapidly 
during this period.
During 2012 London Olympic times, NHK held SHV public show in Japan, USA and UK, 
in cooperation with the BBC and Olympic Broadcasting Services (OBS).
8K, 8000, refers to the width in the name of "8K TV". Four times as the wide, four times 
as the height, 16 times the total number of pixels. To put it back into perspective, a 8K TV 
could be four times as large (30 inches), maintaining the 300ppi.
Obviously, large TV is the trend, and TV manufacturers has already been pushing TV beyond 
1080p. 2013 is a crucial year for 8K resolution UHDTV and video, during which Japan
 Broadcasting Corporation NHK publicly showcased its first new-generation 8K resolution film
 video - a narrative short film named "Beauties À La Carte" to the whole world in celebrated 
Cannes Film Festival. (Related: Free Download 8K Movies)
Actually, early in 2012, Panasonic had showed off its 145" 8K resolution TV at IFA 
exhibitions 
(Berlin Radio Show). Meanwhile just several months later, Sharp announced its
 two 85" 8K LCD TVs at the Consumer Electronics Show (CES) in Las Vegas, one of which
 is a glasses-free 3D one. And Astro Design unveiled its new camera capable of recording
 8K resolution video. And Sony, Samsung and LG joined the trend, later

8K Resolution


8K resolution is the highest ultra high definition television (UHDTV) resolution to exist in digital television and digital cinematography. 8K refers to the horizontal resolution of these formats, which all are on the order of 8,000 pixels, forming the total image dimensions (7680×4320). 8K is a display resolution that may eventually be the successor to 4K resolution. 1080p is the current mainstream HD standard, with TV manufacturers pushing for 4K to become a new standard by 2017, although the feasibility of such a fast transition as well as the practical necessity of a new standard is questionable



One advantage of high-resolution displays such as 8K is to have each pixel be indistinguishable from another to the human eye from a much closer distance. On an 8K screen sized 52 inches, this effect would be achieved in a distance of 50.8 cm (20 inches) from the screen, and on a 92 in screen at 91.44 cm (3 feet) away. Another practical purpose of this resolution is in combination with a cropping technique used in film editing. This allows filmmakers to film in a high resolution such as 8K, with a wide lens, or at a farther distance from a potentially dangerous subject, intending to zoom and crop digitally in post-production, a portion of the original image to match a smaller resolution such as the current industry standard for High-definition televisions (1080p, 720p & 480p).




Few video cameras have the capability to film in 8K, with NHK being one of the only companies to have created a small broadcasting camera with an 8K image sensor. Sony and Red Digital Cinema Camera Company are both working to bring larger 8K sensors in more of their cameras in the coming years. Although 8K will not be a mainstream resolution anytime soon, a major reason filmmakers are pushing for 8K cameras is to get better 4K footage. Through a process called downsampling, using a higher resolution 8K image downsampled to 4K could create a sharper picture with richer colors than a 4K camera would be able to achieve on its own with a lower resolution sensor



Resolutions
8K FUHD is a resolution of 7680 × 4320 (33.2 megapixels) and is one of the two resolutions of ultra high definition television, the other being 4K UHD. In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high data rates. The demand is expected to drive the adoption of video compression standards and to place significant pressure on physical communication networks in the near future.

8K FUHD has four times the horizontal and vertical resolution of the 1080p HDTV format, with sixteen times as many pixels overall.


8K Fulldome
 8k fulldome is a resolution of 8192×8192 (67.1 megapixels) and is the resolution of top-end modern projection for hemispherical fulldome theatres often seen in planetaria. 8K fulldome projects over 4 times the width and over 7.5 times the height resolution of 1080p HDTV format, with 32 times as many pixels overall.

Forget 4K: In Japan, Olympics will be broadcast in 8K resolution

In Japan, they have already moved on from 4K to 8K or as the Japanese public broadcaster NHK calls it 'Super Hi-Vision.'

By: Tech Desk | Published:August 4, 2016 5:58 pm
Japan is moving on to 8K broadcasting for Rio Olympics. 

Wondering if it’s time to buy a 4K TV ? In Japan, they have already moved on from 4K to 8K or as the Japanese public broadcaster NHK calls it ‘Super Hi-Vision.’ While 4K resolution is around 4096×2160, 8K or “Super Hi Vision” is at 7680 x 4320 pixels, making it four times sharper than regular 4K and 16 times sharper than the regular 1080p full HD resolution.
According to NHK’s own website, the broadcaster has started testing this next generation of television technology from this month, and the purpose is to test and validate the technology behind the “Super Hi Vision.” The Verge reports NHK will be installing viewing stations around the country, and plans to showcases footage from Rio Olympics. The reason is that no one has the equipment to receive the 8K content and signal in their homes, just yet.
NHK’s website says they expect full scale broadcasting in 8K to start by 2018, and is looking to boost this specifically by the 2020 Tokyo Olympics. The Super Hi vision channel will have both 4K and 8K content, and allows for 22.2 channel audio as well.
NHK’s website also says they expect commercial manufacturers in the future to provide 8K tuner, to let users experience such content at their homes as well. While August will be specially dedicated to Rio Olympics, NHK will also have drama, nature, history, art, travel, music shows in the 8K Super Hi vision resolution.
While Japan is moving on to 8K, in India 4K is slowly gaining popularity with more manufacturers introducing television sets which support the resolution. Dedicated 4K channels and content are also coming up in India. In 2015, TataSky and d2h were broadcasting select matches of the ICC Cricket World Cup in 4K resolution. Both TataSky and d2h offer dedicated 4K set-top boxes in India, which stream content in Ultra HD format. However in India buying a 4K TV is still expensive, with the minimum cost being close to Rs 37,000 onwards. Brands like Sony, LG cost much more with their 4K resolution TV.
