"We've seen NHK preparing its Super Hi-Vision 8K video since time immemorial. Wouldn't it be nice if the TV broadcast technology was more than just a perpetual research project? If sources for Japan's Nikkei aren't dreaming, the International Telecommunication Union is now 'likely' to declare the format an official standard for broadcasters and TV makers."

As amazing as Super Hi-Vision televisions are, most of the footage we've seen is of slow-moving cityscapes, nature and portraits. We may get more action sequences soon, thanks to a new CMOS sensor capable of picking up 8K (33MP) footage at 120 frames per second.

The current digital cinema standard-bearer is a format called 4K that delivers more than four times the detail of an HDTV image for any given screen size. Today, 4K is making its first push into the consumer video market. Whether its impact at home will rival what it has already done and threatens to do in the film industry remains to be seen. What is clear, however, is that its arrival at our doorsteps is historical and promises a new, even more immersive home theater experience.

If you are in London during the 2012 Olympics without a ticket, there is an alternate way for you to “be present” at certain events. The BBC plans to broadcast part of the games in Ultra High HD (UHD) in select locations. UHD, which has been under development by NHK for years, delivers an “8K4K” (7680 × 4320) pixel image. With a planned commercial introduction in five years, an intermediate production step is necessary. This step, to be generally introduced at CES 2012, is “4K2K.” For many in the broadcast industry, 4K2K will be a surprise — likely an unwanted surprise. For those in the film world, 4K2K is not new at all. Film is routinely telecined to 4K2K files for digital intermediate (DI) processing, and features are shot with 4K2K cameras. In this first of a two-part series, we will begin our exploration of 4K2K by examining several current 4K2K cameras. Doing so will introduce the many challenges involved in this technology.

Raystream Announces Free Trial of HD Video Compression Tool for Businesses, Compliance with GNU LGPL
Raystream Inc. announced that a free trial of its HD video compression service will be available to any business offering HD video content online beginning Friday, December 16, 2011. Raystream's proprietary video compression technology drastically decreases the file size of HD videos -- up to 90 percent, with an average of approximately 70 percent -- with no loss in the quality or crystal clarity for which HD video is known.

-- For example, "Raystream", a recent (and horrifically done) scam company advertised their "amazing proprietary encoding technology", which was of course just x264 on default settings with no modifications. --

Ultra High Definition Television (UHDTV) took an important step towards becoming reality when experts reached agreement on most of the pertinent technical characteristics of this exciting new standard for television. UHDTV marks a leap forward beyond the current standards for High Definition Television (HDTV).
The experts, which include scientists and engineers from around the world, have been working together for several years in the ITU Study Group on Broadcasting Service (ITU-R Study Group 6) to jointly develop and agree on the technical specifications that will successfully create ‘UHDTV’.
A demonstration of UHDTV was provided by the Japanese public service broadcaster NHK at ITU earlier this month. The screen displayed a staggering 33 Million pixels, compared to a maximum 2 million pixels for the highest quality HDTV screens on offer today.
In September 2011, a trial UHDTV link was arranged between London and Amsterdam and plans are under way to cover part of the 2012 London Olympic Games in UHDTV for screening at public venues around the world.

We've seen some tiny PCs, but the (deep breath) Habey SOM-6670 E6XX Tunnel Creek QSeven computer module (phew...) has managed to impress even this crew of jaded tech bloggers. The tiny, Post-it sized board carries an embedded E600 series Atom processor which features the GMA600 integrated GPU -- the same HD video decoding core at work in the Boxee Box and Logitech Revue. This little guy is capable of handling not one, but two 1080p videos at once.

ZTE Corporation has announced a full hardware and software solution integrating low bit rate high-definition (HD), Over the Top (OTT) TV, and multi-screen convergence at this year's Broadband World Forum 2012. The solution supports OTT services on multiple screens for varying devices (TV, PCs, tablets and mobile phones) and employs ZTE's low bit rate HD technology to reduce transmission bandwidth, which assists operators with low-cost network transformation and platform construction and accelerates the deployment of OTT services.
With the improvements in visual mental model-based pre-processing, adaptive transformation, neural network-based vector quantisation, human eye perception of quantised errors and the content-adaptive rate control, ZTE's low bit rate HD coding technique enables the system to transmit 720p video with a code rate of 3Mbps rather than 8Mbps, greatly reducing the pressure of capacity expansion on operators and improving users' service experience.

SAMSUNG is set to launch OLED TVs in Australia in coming months capable of displaying two TV channels at once.
The technology, demonstrated in January at the Consumer Electronics Show in Las Vegas, will allow two people sitting side-by-side to watch two different channels at the same time, in what is a variation of the current 3D technology.
Research firm DisplaySearch said Samsung and LG were set to do battle at the high-end of the Australian market when the OLED TV's finally reached Australia.
Samsung's technology, called "smart dual view" 'is set to overtake conventional 3D as TV's cool new feature.
Rival LG already had released a form of dual view on its Australian TVs for gaming which allows two people to see their aspect of the same game full-screen on the same display using modified 3D glasses.

Video-encoding equipment vendor Envivio has added native support for the new iPad and Apple TV set-top, offering the ability to deliver up to 1080p HD to the devices, and has developed a technology demo of the emerging MPEG-DASH adaptive bit-rate standard. In the demos, live video is being encoded in an Envivio Genesis multi-bit-rate transport stream using Muse, and packaged in MPEG-DASH format by the Envivio Halo network media processor. An Android tablet with an MPEG-DASH decoder client receives the adaptive bit-rate streams, then decodes and displays the video.

A Panasonic insider has revealed images of the recording equipment that will be used to process and record the data heavy format. Called the P2 Tower, the set up has been designed for Super Hi-Vision recording and playback by Panasonic Pro Video. It allows for two hours of Super Hi-Vision recording with AVC-Intracompression to 17 X 2 P2 cards. This is made possible by AVC-Intra’s ability to maintain high image quality with high compression, and the high reliability of P2 cards. It will be able to handle a 7680×4320/60P video signal and the 22.2 channel 24 bit Super Hi-Vision sound format.

Is this just pre-processing? It looks like a sharpen filter, It does make some of the content look sharper but others actually look worse.

Viewers and producers both seek a more realistic viewing experience from cinema and television systems. There are several ways to make the television more immersive. Three paths that are being followed include increasing the field of view, adding depth perception and improving motion rendition.
Producers look to maintain the value of their investments into the future. We already see SD channels commissioning HD programming with a eye on the future. New formats like S3D are gaining a niche following among viewers, but Super HiVision — 4K and 8K — is going to set a new benchmark for video quality.

Are integrated production architectures mature for commodity use, and will 1080p50/60 HDTV become mainstream? David Wood and Hans Hoffmann, who lead the EBU’s technical department, look at likely short- and mid-term developments.
For a number of years two major trends have emerged in programme production. The first is the development of digital workflows that improve production efficiency and reduce costs through flexible, commodity IT-based production architectures.
Current equipment can be made interoperable using the ‘media orchestration system’, with a FIMS adapter that converts the capturing or processing device interface to a common interface standard. New equipment can include the FIMS interface; the specification is now ready.

While there are an increasing number of broadcast TV channels offering 3D HD content, so far the limitations of side-by-side transmission means that resolution tops out at 720p, rather than Full HD 1080p. The engineers at the Japanese NHK Science & Technology Research Laboratories reckon they’ve got the solution, TechOn reports, with their Hybridcast “Dual Stream” 3D system, pairing broadcast with a sync’d IPTV feed.

Work is well underway to create a next-generation video compression standard that could halve bit rates again but, while it may be the foundation for ultra HD services, there are doubts about the value of HEVC (High Efficiency Video Coding) for high-definition TV in mature Pay TV markets. Since the standard will require a new generation of decoders as well, any initial interest for HDTV may be limited to green-field launches.
