aztechya used our news submit to tell us about a jaw dropping breakthrough in high definition television from Japan. Images are so real it makes you sick and that’s not an expression in this case! It was due to the realism of the images and the lack of movement that would usually accompany such visual stimuli. Folks watching were about to blow chunks at the uber-hardware device. Aztechya reminds us that traditional NTSC is 525 lines… This is amazing as it has 4000. Maybe we need to drag out those 10 Terabyte Hyper CDs as they would hold only one 30 minute episode of the Simpsons!
> >UHDV displays images with 4,000 horizontal scanning lines, compared to the 1,000 offered by the current state-of-the-art high definition television (HDTV) technology and just 625 for standard TV broadcasts. When horizontal and vertical scanning are both taken into account a UHDV picture contains 16 times the number of pixels ? individual image components – of HDTV. >NHK, which unveiled details of UHDV for the first time at broadcast technology conference IBC in Amsterdam, said its engineers had to custom-design a video camera, data-storage device and projection system, as no standard broadcasting equipment could cope with their extreme demands. >The camera was built by aligning four 2.5in charge coupled device (CCD) image-capture panels. The projector system uses four liquid crystal-on-silicon panels, two of which process green light while the other two each handle red and blue. These must be aligned to an accuracy of within 0.5 of a pixel – there are 33 million pixels on display – to achieve ultra high definition results. >Recording the massive amounts of data needed to produce UHDV definition also posed a problem for NHK. Its engineers were originally only able to make 34 seconds’ worth of recording. They have now built a disc recorder system made up of 16 HDTV recorder units with a capacity of about 3.5 terabytes, allowing them to shoot 18 minutes of UHDV footage. |
Where will it all end? Will we live long enough to experience a holodeck effect? Or will we go beyond that? Will television ever have a darn thing worth watching at this resolution? Will I hurl when I see it? Inquiring minds want to know 
All kidding aside, thanks for the article aztechya, this is truly a quantum step forward and nothing to joke about. Surely it will help shape the future of video devices and spur the appropriate accompanying technology to compliment it’s power.

it appears that Blizzard underestimated the server capacity required to handle all the gamers, thus resulting in Battle.net servers being overloaded and taken offline at launch. As Diablo III requires the user to be logged in with an uninterrupted internet connection to play, most players were greeted with an "Error 37" on the day of launch, unable to play the game.

In an interview between Forbes and CD Projekt CEO Marcin Iwinski, Iwinski said the truth is that DRM simply does not work. He said the main problem is that the copy protection is cracked within hours of the release of every game, not to mention the money and development wasted to implement it. Those with pirated versions also have a clean and more functional game!
