World's Smallest 8K Camera Moving Forward

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.

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."

In the post world we are not fearful of any new proposals - they can all be handled given enough time and money - although some are too expensive to be practical just yet.

 

As an indication of the size of data that facilities are being asked to tackle, film dailies are commonly of the order of 2.5TB of data per day for a standard 2K show. By contrast an 8K feature at 120fps might average 187TB per day of new data.

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.

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.

Samsung, others demo ‘Super Hi-Vision’ 8K

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.

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.

NHK is one of the world’s few broadcasters to have an NHK roadmap, and has decided to ignore the halfway-house of 4K being pushed by TV manufacturers, which will be used at next year’s FIFA World cup in Brazil.


Plans are already drawn up to develop 8K coverage across Japan via satellite, before starting terrestrial broadcasts on Japan’s equivalent of Freeview.


Other public broadcasters may follow NHK’s lead, allowing 8K technology to develop before taking the expensive step of upgrading from HD.
