According to Wiki, "H.265 or NGVC (Next-generation Video Coding) is a hypothetical future ITU-T recommendation for video compression coding under study for potential development by the ITU-T Video Coding Experts Group(VCEG). The study of potential technology advances which will enable creation of H.265 is a major part of the current work of VCEG.

H.265 was initially foreseen as an entirely new standard and not an extension of H.264 like HVC by the ISO/IEC Moving Picture Experts Group (MPEG). Although some agreements about the goals of an H.265 project have been reached, e.g. computational efficiency and high compression performance,[1][2] the current state of technology does not yet seem mature for creation of an entirely new H.265 standard, and all contributions are modifications to KTA JM11, a reference H.264 encoder by the MPEG/VCEG Joint Video Team. In April 2009, the scope of the project was changed to NGVC, with a H.264+standard being the most likely outcome; in July 2009, a joint meeting of MPEG and VCEG discussed future collaboration on NGVC and HVC, similar to the Joint Video Team effort.

The preliminary requirements for NGVC are bit rate reduction of 50% at the same subjective image quality and computational complexity comparing to H.264 High profile, with computational complexity ranging from 1/2 to 3 times as that of H.264. NGVC should be able to provide 25% bit rate reduction along with 50% reduction in complexity at the same perceived video quality as H.264 High profile."

The ITU discussion can be found in



Prof. Dr. Touradj Ebrahimi mentioned

Though the necessary scope of H.265 is yet largely to be determined, it is agreed that among the goals will be:

  • High coding efficiency, e.g., two times compared with H.264/AVC
  • Computational efficiency, considering both encoder and decoder
  • Loss/error robustness
  • Network friendliness

So far, contributions to VCEG have mainly focused on improving coding efficiency.

To better evaluate these contributions and retain progress, the KTA (Key Technical Area) has been developed as the software platform, using JM11 as the baseline and continuously integrating promising tools.

CNET Review: 3D TV at CES 2010

Three-dimensional TV is coming to a living room near you. But will the technology spur a consumer spending spree like digital and high-definition TV did before it? Or will 3D end up being the next big flop?

One thing is clear, TV manufacturers need something new to get people buying TVs. Over the last couple of years, TV manufacturers have experienced a sales boom as consumers upgrade to digital TVs in anticipation of thegovernment's mandated switch to digital TV broadcasts in February 2009. Eager shoppers have also been upgrading to high-definition TVs as movie studios, cable and satellite operators, and TV broadcasters have begun offering more programming in HD.

But as the economy worsens, the forecast for the TV market is looking grim. The LCD TV market is only expected to grow about 17 percent in terms of units shipped in 2009, according to research firm DisplaySearch. This is down from growth of about 29 percent in 2008. Plasma TV growth is also expected to suffer with the market only expected to grow by about 5 percent in 2009 compared with a 24 percent rise in 2008, DisplaySearch said.

As a result, TV makers are looking for the next hot thing to attract new consumers. And some are hoping 3D TVs could be it.

At this year's Consumer Electronics Show in Las Vegas, four of the top selling TV manufacturers--Samsung Electronics, Sony, LG Electronics and Panasonic--showed off their latest versions of 3D TVs. Panasonic set up a mini-home theater where its 103-inch, plasma 3D screen showed clips from New Line Cinema's Journey to the Center of the Earth and Walt Disney Pictures' animated film Bolt. They also showed high-definition 3D footage from NBC's broadcast of the 2008 Summer Olympics in Beijing.

While some manufacturers, such as Mitsubishi, Phillips, Samsung, and Sharp, have already begun selling 3D-ready TVs, the top four manufacturers plan to have new, advanced 3D TVs on sale toward the end of 2009 and into 2010.

But the big question is whether consumers, particularly American consumers, will be willing to upgrade to a new TV just because it has 3D. Pricing for today's 3D ready TVs is comparable to other flat-screen HDTVs. Samsung and Mitsubishi currently sell their 3D-ready TVs for between $1,000 and $2,800, depending on functionality. These prices are in line with average prices for HDTVs that don't offer 3D readiness.

Keisuke Suetsugi, a manager for the audio visual center at Panasonic, believes that even the newer, more advanced 3D TVs will not cost much more than TVs without 3D. So for consumers already in the market for a TV, adding 3D readiness might not add much cost. But will 3D be enough to compel cutting-edge consumers to replace their 2- or 3-year-old TVs? That's what TV manufactures are hoping.

Three-dimensional movies have been around since the 1950s. And for most of its lifespan the technology has been seen more as a gimmick than something that truly enhances the movie-going experience. But newer technology and advanced special effects are helping 3D movies break into the mainstream.

TV makers believe that much of the demand for 3D will come from Hollywood, which is pushing 3D in a big way. Last year, DreamWorks announced that all its films will be produced for 3D production beginning in 2009. The company has partnered with chipmaker Intel to build processors that will help make 3D in the home a reality.

Sports leagues have also been experimenting with 3D technology. Both the National Basketball Association and theNational Football League have broadcast events and games in 3D to movie theaters.

From a technical standpoint, the technology is available and mature enough today to make 3D TVs available at a reasonable cost to consumers. But there are still a few drawbacks that could prevent 3D TV from becoming the next big thing in home entertainment.

For one, to get the really cool, immersive 3D experience without getting a massive head-ache, consumers will have to wear special glasses when they're watching TV in 3D. The glasses are needed because 3D imaging requires sending a different image to each eye. And the glasses help merge the images in the mind and trick the brain into thinking that it's seeing a single 3D image.

I checked out Panasonic's home theater in 3D. I must admit, the experience was phenomenal. I felt like I was on the floor at the Olympics opening ceremonies in Beijing right alongside the hundreds of dancers and drummers. But without the glasses, the image looked fuzzy.

Panasonic's Suetsugi admits that in a perfect world, consumers should be able to have the immersive 3D experience without wearing glasses. But he said that it will be at least 10 years before the technology is advanced enough to provide a similarly robust 3D experience without glasses.

"Glassless 3D would be ideal," he said. "But it's just not possible to do that now and get the same quality experience. You would need at least 50 times more pixels to get a display to provide the same 3D experience that we provide with our TV. We are still 10 years away from that kind of technology."

Taesoo Park, a chief research engineer at LG, which makes 3D display monitors for advertising and digital signage, agrees. LG plans to start selling its 3D TVs, which require glasses, late in 2009 or in the beginning of 2010. Its glassless digital signs were also on display at CES.

"Glassless 3D is available today for digital signage and advertising," Park explained. "But the technology is not ready for TVs, because it would hurt people's eyes or give them a headache to look at today's 3D displays for any length of time. It will be at least a decade before we can get the technology to make glassless TV a reality."

That said, some manufacturers claim they have developed technology that doesn't require glasses. Phillips uses a technology it calls WOWvx. 3M and Toshiba also showed off glassless 3D screens at CES. 3M has created a thin film technology that can be used to beam light selectively to the viewer's right and left eyes.

But glasses aren't the only thing that could hold back 3D adoption. Currently, there's no standard way to get 3D footage from the movie studios or from a live broadcasts to the home. Companies, such as Panasonic, are already working on developing a standard. But industry watchers fear that competing standards could emerge and spur another "format" war like the one that pitted HD DVD and Blu-ray against each other.

Panasonic's Suetsugi said he is hopeful that a common standard for 3D Blu-ray hardware, software, and TVs will emerge sometime this year, paving the way for 3D TV sales to pick up in 2010.

In addition to the standards issue, another hurdle for 3D TV has to do with the high production cost of shooting movies and events in 3D, as well as, the high cost of transporting the video across networks. Three-dimensional video requires multiple cameras for shooting. And it also requires multiple high-definition streams for transporting the video over carrier networks.

Regular standard definition television broadcasts consume more bandwidth capacity than other types of traffic like audio or text. High-definition video eats up even more. And it would likely take at least two full high-definition channels to broadcast live just one game in 3D.

This means that service providers, such as cable or satellite operators, would have to upgrade their infrastructure to handle the high bandwidth demands. Verizon, which is deploying fiber directly to consumers' homes for its Fios service, is already in good shape. But others such as Comcast and Time Warner Cable, are already finding it difficult to carve out enough bandwidth for regular HD video as well as Internet video on their networks.

"Transporting live, high-definition 3D streams is very expensive," said Steve Hellmuth, executive vice president of technology and operations for the NBA. "So there has to be sufficient demand and a pool of content before satellite and cable operators will devote resources to delivering it. I really think that Hollywood will initially drive adoption of 3D in the home."

MVC is Adopted by Blu-ray 3D Disc

December 17, 2009 03:54 PM ET

Computerworld - The Blu-ray Disc Association announced today that it has finalized the 3-D Disc Specification, which includes support for the PlayStation 3. The format will be display agnostic, supporting any 3-D television, including LCD and Plasma models.

The news comes less than a week after LG Electronics Inc. announced it expects to ship 400,000 3-D-enabled televisions next year, and 3.4 million in 2011. The market for 3-D television is expected to be a $1.1 billion in 2010. By 2015, it's expected to skyrocket to $15.8 billion, according to market research firm DisplaySearch.

3-D Blu-ray players will project a 1080p image for each eye. Special glasses required for viewing 3-D brings the two images together to create the additional affect of depth.

"From a technological perspective, it is simply the best available platform for bringing 3D into the home," Benn Carr, chairman of the Blu-ray Disk Association 3-D Task Force said in a statement.

The Blu-ray 3-D specification allows PS3 game consoles to play back Blu-ray 3-D content in 3-D. The specification also supports 2-D discs in upcoming 3-D players and allows 2-D playback of Blu-ray 3-D discs on the large installed base of Blu-ray Disc players.

The Blu-ray 3D specification calls for encoding 3D video using the Multiview Video Coding (MVC) codec, an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently supported by all Blu-ray Disc players.

MPEG4-MVC compresses both left and right eye views with a typical 50% overhead compared to equivalent 2D content, and can provide full 1080p resolution backward compatibility with current 2D Blu-ray Disc players. The specification also incorporates enhanced graphic features for 3D. These features provide a new experience for users, enabling navigation using 3D graphic menus and displaying 3D subtitles positioned in 3D video.

Victor Matsuda, chairman of the Blu-ray Disc Association Global Promotions Committee, said that in 2009 movie goers showed an overwhelming preference for 3-D when presented with the option of 3-D or 2-D.

"We believe this demand for 3-D content will carry over into the home now that we have, in Blu-ray Disc, a medium that can deliver a quality Full HD 3-D experience to the living room," Matsuda said in a statement.

3D Video & The MVC Standard

Three-dimensional video services are predicted to be the next big thing in entertainment and communication industries. Concepts using 3D video in science fiction have fueled the excitement around this topic. With the aid of recent advances in capture, display and compression technologies, 3D video is taking the next step towards becoming a reality in the consumer domain with realistic opportunities.

Applications of 3D Video

One of the most exciting applications that could be enabled by 3D video is telepresence (or virtual reality) - delivering to people the feeling of being immersed in a place other than their actual location. This could enable new ways of collaboration, and increase the efficiency of online meetings.

A similar application is the extension of traditional TV entertainment using displays capable of 3D rendering. The simplest form of 3DTV is a stereoscopic TV, where the display is capable of rendering two views, one for each eye, so the scene is perceived as 3D.

More sophisticated displays are able to render and display multiple views in such a way that the perceived 3D video depends on the user’s location with respect to the TV For example, the user can move his/her head to see what is behind a certain object in a scene while watching TV. This feature brings a new form of interactivity and an immersive feeling to TV viewers that have never been experienced before.

The Joint Video Team of the Video Coding Experts Group of the ITU-T and the Moving Picture Experts Group (MPEG) of ISO/IEC has recently devoted part of its effort to extend the widely deployed H.264/AVC standard to enable these new services and developed the Multiview Video Coding (MVC) extension. The MVC standard has the following features that are useful in terms of enabling many of the 3D video services:

1. Compression of 3D Video

Multiview video sequences are captured by different cameras in different positions and through different angles, they are just different representations of the same scene. Therefore, there exists an additional redundancy in the view direction for 3D video, called view redundancy. The MVC standard utilizes prediction between different views to exploit this redundancy and improve the compression ratio.

2. Scalability and Adaptation

To meet the requirements of the applications exemplified above, scalability and adaptability also need to be supported. For example, in 3DTV scenario advanced displays capable of displaying multiple views would be decoding more views than stereoscopic displays that display only two views. The MVC standard defines efficient ways so that any subset of the views is easily separable from the entire bitstream. As the regular two dimensional TV applications are still widely used, backwards compatibility has been an important target for MVC. The MVC standard achieved backwards compatibility by defining the bitstream so that a compliant H.264/AVC decoder can decode a single 2D view and discard the rest of the data, whereas a compliant MVC decoder can decode all the views and generate the 3D video. Backwards compatibility is also supported by the related communication protocols for transport over the MPEG-2 Transport Stream and the Internet Protocol (IP) – a device capable of receiving an H.264/AVC stream over the MPEG-2 Transport Stream or the Real-Time Transport Protocol over IP is also capable of receiving an MVC stream over these protocols.

3. Computational Complexity

The amount of information that needs to be processed in 3D video is significantly higher than that of regular 2D video. Moreover, the additional dependency between views could potentially become problematic in terms of implementation complexity. In order to enable practical implementations and reduce the complexity of 3D video codecs, the MVC standard utilizes efficient ways to buffer the pictures used for prediction, and enable parallel processing of separate views. In addition, the MVC standard does not change the underlying coding tools used in the H.264/AVC standard, so that the existing hardware accelerators and optimized software implementations that are widely deployed could be reused.

4.1 Mobile 3D Video

Mobile 3D

With recent advances in capture and display technologies, 3D video communication and entertainment services are expected to become reality and redefine the communication and entertainment services with high immersion. To enable these exciting new services, Joint Video Team (JVT) of ITU-T and MPEG has devoted its recent efforts to extend the widely deployed H.264/AVC standard for multi-view video coding (MVC). MVC provides superior network robustness and compression performance for delivering 3D video by e.g. taking advantage of the inter-view dependencies of the different visual channels. In addition, its backwards compatibility with H.264/AVC codecs makes it widely interoperable in environments having both 2D and 3D capable devices.

4.2 Nokia's MVC Software

Nokia Research Center has developed a highly optimized MVC decoder running on Maemo platform, and demonstrated a natural real-time 3D movie playback on a modified Nokia N800 internet tablet with an integrated auto-stereoscopic display. The prototype was showcased at IEEE 3DTV-CON and Nokia World 2008. The source code implementing the 3D Video playback demos mentioned above is available for download now. The Nokia’s MVC software includes two modules:

1. MVC Encoder, which runs in PC and configured to generate MVC compliant bitstreams
2. MVC Decoder is a player, fully optimized for the Maemo platform, and decodes stereoscopic MVC bitstreams.


Nokia Research Center welcomes any feedback on the software, in terms of bug-fixes or additional functionalities. Please send all your questions/comments or to project team.
