Does Ultra HDTV signal the end of three-sensor cameras? | Ultra High Definition Television (UHDTV) | Scoop.it

 

In the coming world of 4 and 8K resolution video cameras, a tried and true technology—the three-sensor camera—may fall to the wayside in favor of more cost-effective single-sensor image-making tools.

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.

NAB: Speakers Discuss Early 8K Activity

NAB: Speakers Discuss Early 8K Activity | Ultra High Definition Television (UHDTV) | Scoop.it

 

4K is a pervasive topic this week at the NAB Show, but hang on: The 8K flavor of Ultra HD -- representing a whopping 16 times the picture resolution as today’s HD -- is also generating discussion on some panels.

 

Jim Houston, principal of Starwatcher Digital and AMPAS Scitech Council member, even predicted that it would be as easy to accommodate 8K 120 frames per second in a decade as it is do 2K today.

 

 

To illustrate the difference in file sizes, he related that today dailies can account for roughly 2.5 TB of data per day, while 8K at 120 fps could bring that number to 187TB.
