Super Hi-vision (Ultrahigh-Definition Wide-Screen System with 4000 Scanning Lines) is the new standard in video viewing.
NHK Science & Technical Research Laboratories has created a new piece of engineering genius in its 8K Television System “Super Hi-vision”. This newest imaging technology upon us already in Japan and destined to give screen coverage of the 2012 Olympics on big screens in city centers across Britain. The BBC plans to use the technology, named Super Hi-Vision, just 4 years from now in 2012 but it was developed in Japan in 2005.
Does this incredible new resolution show us that man-machine interfaces with even higher resolutions are possible, and soon? What of true 3D with no glasses, 4D and better and what of BLU-RAY, Violet Ray and Ultra-Violet Ray?
NHK’s new image creation uses a video format with 7680 x 4320 pixels (16 times higher than standard Hi-vision, NHK’s HDTV system). 4000 scanning lines deliver ultra-clear, realistic three-dimensional images that can be achieved only by ultrahigh-definition technology.
Scanning lines are not visible even when relatively close to the screen. And a wider viewing angle provides a stronger sense of a reality.
The 3-D audio system has 24 speakers dramatically enhancing live presence.
Around the world electronics consumers have been buying the newest high definition TVs and BLU-RAY players to go with them but with this newest high-definition TV Japanese broadcasters and the BBC have finalized a system 33 times more detailed than the best sets currently for sale.
By 2015 NHK hopes to begin test broadcasts of its Super Hi-Vision system, with full-time public broadcasts scheduled for 2025.
Nobuyuki Hiruma, associate director at NHK’s laboratories in Tokyo, says that “Super Hi-Vision TV approaches the realism of human vision.” I fact it was based on research into human vision.
Super Hi-Vision exists only at NHK’s Broadcasting Center in Tokyo, where it is projected on to a 10 meter (yard) by 5.5 meter (yard) screen, with sound coming from 22 multi-layered speakers capable of replicating the sound of a concert hall. 24 discrete channel speakers are the actual technical goal.
Only 20 minutes of Ultrahigh-Definition can be recorded at a time and it must be edited frame by frame. Making a back-up takes engineers an whole night, and after a week they have only enough material for one hour of Super Hi-Vision TV.
Sitting just three meters (yards) from a 450-inch screen, viewers says “sometimes we suffer motion sickness,” says Masaru Kanazawa, research engineer on the SHV project.
While such a huge screens would not fit into most living rooms, Kanazawa thinks they soon might anyway.
Hiroyuki Ohira, GM of Pioneer’s plasma development center in Yamanashi, is in charge of the same team that, in the 1990s, invented the first high-definition plasma screens. “We are trying to develop a Super Hi-Vision panel to help NHK realize its broadcast plans,” he said.
The BBC and NHK often collaborate on program production, most recently on the David Attenborough-narrated documentary Planet Earth which was filmed in high definition and produced a number of new techniques.
November of 2007 NHK strapped its high definition television cameras to a Japan Aerospace Exploration Agency lunar probe to film an “Earth rise” over the moon in Ultrahigh-Definition detail.
To overcome the problem of how to transmit huge amounts of data remains NHK is uses Dirac video compression technology for its Super Hi-Vision testing, this is a BBC technology.
Using large outdoor screens and with the aid of Participate, an EU-funded project promoting public interaction with new technology, BBC engineers are involved in Super Hi-Vision events. “Super Hi-Vision feeds nicely into that and it’s definitely a long-term ambition,” said Andy Bower, interim controller of the BBC Research and Innovation Centre.
As you how to overcome data storage three dimensional holographic images enable more information to be stored in a much smaller space, preventing information overflow. This technology comes from Michael E. Thomas owner of Colossal Storage Corporation of Fremont California.
Also called Volume Holographic Optical Storage Nanotechnology the Volume (3 D) Holographic Optical Drive technology plans to push future storage densities of optical mass storage over 40,000 Terabits/cu.cm. To compare with magnetic hard drives of today which are around at 60 gigabits one can understand that Mr. Thomas’ optically assisted drives at 45 gigabits/sq. in. and contact recording AFM, STM, SPM or SFM, i.e. atomic force microscope and their derivatives, at about 300 gigabits/sq.in mean a storage capacity far beyond what current available methods provide.
A BLU-RAY player of the future might use tiny 3.5″ discs based on 3 D Volume Holographic Mass Data Storage using the Einstein/Planck Theory of Energy Quantum Electrons to control molecular properties by an atom’s electron movement/displacement.
Using Ultraviolet/Blue laser diodes with Voltage transducer to write, new definitions of term include photon/laser induced electrical field poling and UV/Blue laser diode and Nanooptical transistors or Nanofloating gates Mos Fet to read.
To be created for this device are ferroelectric perovskite’s dipole dielectrics giving properties allowing write, erase and storage states in nanocrystal memories. A Semiconductor Integrated Optical Read / Write Head will play back the data.
Having an almost infinite storage persistence of data fast read/write control of ferroelectric molecules will allow increasing areal densities and data transfer rates of data between the random mass storage device to system requirements and this will increase mass storage bandwidth needs.
For the new BLU-RAY ULTRA-VIOLET RAY players of tomorrow a transmission speed of extraordinary magnitude will be needed to send movies over the internet.
Super Hi-Vision live relay over IP
On December 31, 2006 a global first happened when a Super Hi-Vision feed of the 57th Kohaku Uta Gassen (NHK’s annual “Red & White Song Battle” which is the most-watched TV event of the year in Japan) was relayed long-distance over an IP network from the Tokyo venue and displayed on a giant 450-inch screen in an Osaka studio. There, members of the public enjoyed ultra-realistic picture and sound reproduction equivalent to a VIP seat at the actual live event.
Using a codec developed by NHK for efficient transmission and broadcast of Super Hi-Vision signals the encoder compresses the video signal from approximately 24Gbps down to 180-600Mbps and the audio from 28Mbps to 7-28Mbps. The reduced bit rate makes it possible to transmit the signal and to record even an event of long duration like Kohaku Uta Gassen.
A live viewing at the 2005 World Exposition, Aichi, Japan (Expo 2005 Aichi) was held from March to September 2005 on the theme “Wisdom of Nature”. At NHK booth, Super Hi-vision images were displayed on a 600-inch screen. With about 8,000 visitors each day, for six months some 1,560,000 people have seen these images and enjoyed crystal-clear ultrahigh-definition wide-screen system on the big screen.
For the first time in history a live-relay optical transmission of Super Hi-Vision succeeded in 2 November, 2007. The transmission was between Kamogawa of Chiba prefecture and NHK Science & Technical Research Laboratories. Kamogawa is famous for Kamogawa Sea World aquarium and about 260 km away from NHK Labs.
The long-haul optical transmission of uncompressed video and audio signals by using DWDM (Dense Wavelength Division Multiplexing) technique was a groundbreaking moment.
And so your BLU-RAY player of the future might be in Ultra-Violet or it could come strictly as a download from a new Super-Pipe Internet IV right into your mind.
Stand back, the Future is already Old.
