Full HD isn't the ultimate resolution anymore. Televisions have moved on, to greater and better resolutions. 4K, for the lack of content at present, is supposed to become the standard for Blu-ray discs and even for HD channels broadcasts, at some point of time. Let us run you through what 4K is all about.




What is 4K
The term 4K denotes a very specific resolution - 4096x2160 pixels, to be precise. This is the set resolution for anything that is recorded as true 4K content. Some people refer to any content with around 4000 horizontal pixels as 5K but that is strictly not true.

Is it the new Full HD?
Well, your Full HD TV has a resolution of 1920x1080 pixels. Along the way, silently, Ultra HD TVs came along with the resolution of 3840x2160 pixels. The 4K resolution display will have four times the total number of pixels on a 1920x1080p display.

Can any TV be 4K?
 No, the answer is that simple. Which is why, companies are spending a lot of money on making new 4K TVs.

So, can I buy a 4K TV?
Sony kicked it off with the mammoth like 84-inch 84X9005. This TV costs more than
$25,000 in the US. The company recently launched 65-inch and 55-inch versions for affordable costs (and definitely that's too is not affordable by all). LG got into the game as well, with the 84-inch HD 3D TV.
At the moment, unless you have a lot of spare cash lying around, that you desperately need splurge on, 4K TVs deserve the waiting game.

Where do I get the 4K content?
This is where things get tricky. With such a huge boost in the resolution, any existing 1080p content will also look weird on a 4K TV, no matter if somehow even upscaled to that resolution.
This brings us to the question of native 4K content. Yes, Sony is now selling the FMP-X1 4K media player for around US $800 in the U.S, with some content preloaded. The device has a 2TB built-in hard drive and web connectivity. The service that Sony is talking about, the Sony Video Unlimited 4K, is supposed to be rolled out later this year, and is expected to refresh the 4K movies and TV show line-up regularly. However, keeping the kind of broadband speeds most of us get here, we won't even dare consider downloading a 4K movie, if this service wwere to launch in Nepal in the near furture.
Alternatively, this content will also cost a considerable amount of money. It will not come cheap, with prices being quoted ranging aroung $30-$40 for buying a 4K movie in 4K discs

When will TV channels become 4K?
That is still quite some distance away. After the first 4K TVs from Sony and LG were unveiled late last year, a couple of channels did go live, one in Europe and one in South Korea. But at the moment, thats pretty much it. Most broadcasters expect them to start beaming before 2014, actually 2015 to be realstic. The FIFA 2014 World Cup  Final from Brazil is scheduled to get a 4K broadcast in Japan, but that is more the "on-demand" broadcast.

Forget the point-and-shoot Galaxy Camera from last year and feast your eyes on the Samsung Galaxy NX instead. It's the world's first ever interchangeable lens camera running on android and supporting 4G LTE cellular data. It lacks manual dials, but the Galaxy NX has a 20.3 MP APS-C sensor, 1/6000 shutter speed, built-in Wi-Fi, 16 GB onboard storage and a few other bells and whistles to push it into the high-end cameras category. It also lests you to connect to some popular social networking sites like facebook and lets you upload your pics directly.

Samsung Galaxy Gear

Samsung finally beat Apple into the wearable gadgets segment by giving the world a sneak peek into the Galaxy Gear, its first smartwatch. Sporting a 1.63-inch Super AMOLED (320x320 pixel res) display, 4GB internal memory, 512 MB RAM and an 800 MHz processor, the Gear's designed tp be a companion device for a smartphone, connecting over Bluetooth, pulling notifications and voice calls. It runs on a custom build of Android, offering good voice recognition features to interact with your phones in a handsfree mode. It also supports quite a variety of apps.

Samsung Galaxy Note 3

There's a brand new Galaxy Note phablet on its way for all who can't decide between a tablet or smartphone purchase. The device's 5.7-inch Super AMOLED screen touts a Full HD resolution and its frame packs a 13MP shooter with a whole host of dazzling features. It's slated to be available in two configs: the LTE version sporting a quad-core 2.3 GHz Krait 400, while the 3G only model featuring a quad-core 1.9 GHz Cortex A15 or quad-core 1.3GHz Cortex A7 SoC. It packs in a whooping 3GB of RAM, which should deliver a pleasant user experience and performance. And it comes with a stylus, too.

China has build a new super computer which is about 74% faster than present fastest super computer at USA and Japan.Its name is given Tianhe-2 (also called Milkyway-2).

According to Computer World, the supercomputer can reach speeds of up to 54.9 petaflops. It has been built with Intel's chips, but also includes Chinese technology. The country's government has spent about $290 million building the computer.

It operates as fast as 30.7 petaflops - quadrillions of calculations per second.It runs Linux and has storage of 12.4 PB and memory of 1.4 PB.It also has 48,000 Xeon Phi chips, which is a co-processor based on Intel's Many Integrated Core architecture. Each of the Xeon Phi processors is capable of more than a Teraflop of speed.

Sony and Panasonic have announced that they're working together to develop the next generation optical discs. These discs will be capable of holding 300GB of data - considerably higher than the 50 GB that a dual-layer Blue-Ray can hold at  the moment - which can be read by standard players and hardware. Both companies believe that the discs will be ready for use by the end of 2015.

"Optical discs have excellent properties to protect them against the environment, such as dust resistance and water resistance and can also with stand changes in temperature and humidity when stored. They also allow inter-generational compatibility between different formats, ensuring that data can continue to read even as formats evolve. This makes them robust medium for long-term storage of content"said the jkoint press release from Sony and Panasonic.

"Both companies have previously developed products based on the Blu0ray format, leveranging the strength of optical discs. However, both Song and Panasonic recognized that optical discs will need to accomodate mucu larger volumes of storage in years to come given the expected furture growth in the archive marked and responded by formulating this agreement."

It's easy to understand why Sony wants to support the evolution with 4k content being critically important to irs 4k products since these discs will be capable of storing 4k movies.
