Reputable manufacturers of televisions, computers and mobile telephones, working jointly with Fraunhofer researchers, are developing a new standard for data transmission: “High Efficiency Video Coding”, or HEVC for short. This video codec will be unveiled in Amsterdam at the IBC trade show, from September 7 - 11, 2012 (Hall 8, Booth B80).
The opening ceremonies for the Olympic Games captivated countless viewers all over the world in front of their televisions, astounding them with a gigantic show. Relatively few people were able to have a live experience of the spectacle at the London stadium. Still, some of the fans watching the show felt as if they were there live, even though they were only sitting in front of a large cinema screen. That’s because a few movie theaters showed the opening ceremonies in 8K-resolution, which corresponds to 33 megapixels.
The resolution on home televisions will soon be enhanced even further, conveying the feeling of being right in the middle of the action, instead of just watching from the sidelines. Indeed, the successor to the full HD television set is already penetrating the market: the 4K display, also called 2160p format. These televisions have four times as many pixels as the TVs in our living rooms today. Still, the continuously growing number of pixels must also be fed with the matching content, so that the capabilities of the high resolution television can also be utilized. But to do so has always been tied to immense costs, until recently, and therefore was only considered for major events, like the Olympic Games.
The previous standard for encoding data and sending it from the broadcaster to the home television set is known as H.264/MPEG-4 AVC. Theoretically, it has certainly been up to handling the mass of data; however practically, the broadcasting of higher resolution entails substantial costs: because an additional channel is needed for television broadcasts, and for Internet transmission, the server needs a wider bandwidth. A majority of the reputable electronics manufacturers have now joined forces to develop a new broadcasting standard together: HEVC, short for "High Efficiency Video Coding." The labs at the Fraunhofer Heinrich-Hertz-Institute HHI in Berlin, which played a critical role in the engineering of the H.264 predecessor standard, also made a substantial contribution to this new standard.Twice as efficient as H.264
Compared to H.264, since the computational effort for the higher coding efficiency increases sharply to encode or decode the images, HEVC in the standard design allows computer units to work parallel with each other. Either the image is separated out into several parts, known as tiles, whereupon each processor works on one of them, or in the wave front method, where the processors each handle one block of lines in the image. These methods allow encoder manufacturers to get implementations and products to market rapidly.
The development is scheduled for completion in January 2013. Thereafter, new televisions, smartphones and PC units will presumably contain decoders that convert data – encoded with HEVC – into high-resolution television images. The HEVC standard for 3D movies should follow in one to two years. HEVC will be presented at the IBC in Amsterdam from September 7-11, 2012 in Hall 8, Booth B80. Visitors can watch a full HD film on an HD television being converted live by the HEVC decoder into high-resolution television pictures. They can change movies, pause playback, fast forward and also rewind.Standard for video telephony and video streaming as well

China's Loess Plateau was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to a new report from University of Arizona geoscientists. The study is the first to explain how the steep-fronted plateau formed.

The leaves of the lotus flower, and other natural surfaces that repel water and dirt, have been the model for many types of engineered liquid-repelling surfaces. As slippery as these surfaces are, however, tiny water droplets still stick to them. Now, Penn State researchers have developed nano/micro-textured, highly slippery surfaces able to outperform these naturally inspired coatings, particularly when the water is a vapor or tiny droplets.
Enhancing the mobility of liquid droplets on rough surfaces could improve condensation heat transfer for power-plant heat exchangers, create more efficient...
Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published in Science has found. Without informed management, some forests could convert to shrublands or grasslands within the coming decades.
"While we have been trying to manage for resilience of 20th century conditions, we realize now that we must prepare for transformations and attempt to ease...
A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.
The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...
A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).
Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...
