8K Train Can't Be Stopped

8K Train Can't Be Stopped | Ultra High Definition Television (UHDTV) | Scoop.it


While U.S. broadcasters are wrestling with how and when to utilize 4K (aka Ultra High Definition or UHDTV) in their production workflows, or if at all, the Japanese broadcast industry is determined to move to a higher resolution level, namely 8K.


That's 16 times the resolution of 1080-line HD, or 7680 × 4320 (33.1 megapixels, 12-bit processing). Uncompressed, an 8K 60fps image produces a data rate of about 24 Gbps.

Japan's national broadcaster, NHK, plans to deploy equipment that complies with the bandwidth-hungry format at the Tokyo Olympics in 2020.


In January of this year, NHK's science and research laboratories said it successfully transmitted 8K television signals via a single standard UHF terrestrial broadcast channel over a distance of 27 km.


The field test, conducted on Jan. 20 was performed as a follow-up to a May 2012 demonstration in which the UHD signal was sent slightly more than four km.


For all those professionals trying to decide whether now is the time to buy a 4K camera, talk and testing of 8K systems is not doing anyone any favors.

The march towards Ultra HD seems to be taking two paths - 4K and 8K, but with some U.S. Broadcasters expressing doubts about 4K, is Japan's 8K Super Hi-Vision initiative even viable?

Forget 4K, it's an 8K TV you Want! | Ultra High Definition Television (UHDTV) | Scoop.it

4K has been the talk of CES and looks likely to go big in 2014, but is it needed?


Invest in 4K now and you can be sure that it'll only be a few years before a more expensive 8K set, with 8K movies, seems necessary.


Such is the rate at which formats evolve now that HD TV is pretty much still a teenager by TV standards.

Just in case you think that the 4K resolution (3840*2160) is a thing to last for a long time, think again since 8K (7680*4320) technology may be approaching faster than expected.


The fact that not only Samsung, but also Sharp TVs (actually, Sharp has been demonstrating prototype 8K screens for a couple of years now to show off advantages of its IGZO display panel technology) and Philips are showcasing prototype 8K devices implies that the technology is not that far away from commercialization.


In Japan, 8K UHD TVs may become available as early as in 2016, then it will take another year or more for other markets to get their first televisions with 7680*4320 resolution.


Mass availability of 4K and then 8K TVs and displays will greatly depend on the price of UHD panels.


Once quality 4K screens hit mainstream price-points, the high-end of the market will likely move on to 8K.

For Japan, TV technology is a high priority

For Japan, TV technology is a high priority | Ultra High Definition Television (UHDTV) | Scoop.it


While many TV makers are working on developing 4K technology, Japan is looking beyond.


In June, more than 20 competing Japanese manufacturers and broadcasters - including Sony, Sharp, Toshiba, Panasonic, NTV and the NHK - put aside their differences and joined forces in a government-backed collaborative forum called "NexTV-F."


Their goals are simple: promote the development and adoption of UHD TV, and ensure that Japan is first in the world to broadcast in 8K.


8K - known as "Super Hi-Vision" in Japan - boasts four times the resolution of 4K, and 16 times that of current full HD.


The U.N.'s International Telecommunication Union (ITU) finalized the standard last year, and some in the industry have suggested it may be the highest practical resolution for consumer displays.

The Future of Ultra-HD: A Recent SMPTE Meeting Update

The Future of Ultra-HD: A Recent SMPTE Meeting Update | Ultra High Definition Television (UHDTV) | Scoop.it


Two standards are actually being developed. Simply called UHDTV1 and UHDTV2, the easiest way to distinguish them is by their frame dimensions.


UHDTV1 would have a 4k resolution of 3,840 x 2,160 pixels whereas UHDTV2 would have a whopping 8k resolution of 7,680 x 4,320 pixels.


The standards would contain 10 and 12 bit depth, with chroma subsampling options at 4:4:4, 4:2:2 and 4:2:0. 8 bit, as well as interlacing and fractional framerates, would be discarded.


The likely base framerate would be 120 frames per second, due in part that 120 is divisible by many popular framerates such as 24, 30, and 60.


At such a high framerate, the “flicker fusion threshold,” a technical term for image flicker, would be greatly reduced.


Andre Bontems's insight:


One comment in this article will lead you to pause:

" ... More frames means more data, and with 8k cameras shooting up to 72 gigabits per second, this data management soon becomes serious."

Keeping apace with camera technology is like running a race where the finish line keeps on moving.

Just as the next generation of games consoles go on sale boasting the ability to display 4K images (although for the moment only those with the salary of a pro-footballer can afford screens able to make use of all those pixels) Japanese broadcaster NHK has started to film and broadcast events in 8K.

NHK are so excited about the technology that they have commissioned filmmakers to make short films showcasing 8K, which were screened at the recent Tokyo International Film Festival.

8K Ultra High Definition Endoscope Offers Unprecedented Video from Inside Body | Ultra High Definition Television (UHDTV) | Scoop.it


High definition video endoscopes with a resolution in the range of 1080p are still relatively new to the market.


They allow for significantly improved visualization of the body’s interior, helping doctors to perform a variety of procedures with confidence and precision.


Beyond 1080p HD video is the 4k standard that’s already showing up on electronic store shelves, but soon we should see 8K video coming out, which has the resolution equivalent to 16 1080p screens


In Japan there’s already an endoscope capable of transmitting 8K video for a truly unprecendented look inside the body.

Japan’s public broadcaster has successfully broadcast long-distance digital terrestrial signals for its Super Hi-Vision 8K format, sending massive amounts of data over UHF airwaves, but despite this test it’s unclear if many Japanese will be watching 8K TV by the time Tokyo hosts the Olympics in 2020.


Nippon Hoso Kyokai (NHK) Science & Technology Research Laboratories conducted the test from its bureau in Hitoyoshi, Kumamoto Prefecture, in southern Japan, and managed to send the 8K Ultra High Definition TV signal to a receiving station 27 kilometers away using a single UHF channel.

Ultra HD at CES: 'The Chicken and Egg Have Left the Barn'

This week at the International CES, there’s been plenty of comments that the “Ultra HD train has left the station,” while others warn there’s still a “chicken and egg” dilemma and success is dependent on the right combination of factors including set penetration, a delivery infrastructure and available content.

But speaking on one of several panels produced by the International 3D and Advanced Imaging Society, Stephan Heimbecher, head of innovation and standards at Sky Deutschland, got a big laugh when he summed up, “The chicken and egg have left the barn.”

World's Smallest 8K Camera Moving Forward | Ultra High Definition Television (UHDTV) | Scoop.it

Astro Design's 8K camera is moving forward as Japan looks to broadcast in UHD 8K by 202.


Based on a design similar to the Sony F5 and F55, the camera is essentially a head, or brain, that records directly to an external recorder via an optical output with XLR connectors for audio.


The chip is huge, too, at 2.5 inches. 


The recorders are being developed in tandem and compresses at 1 over 6 to be recorded. 


It can record at 60p with plans for frame rates up to 120 fps. 


Currently, there’s only a prototype, but Astro Design is expecting the 8K camera to run about $300,000.
