By | July 28, 2015

The digital space is spreading its net all over the globe and so are the new technologies. Today most of us cannot even dream about living a life without gadgets, smartphones, HD TV’s, laptops, PS4, Xbox etc, and why not, the techno world is offering so much today that a life would fall short to grab each one of them.

Earlier days, when any 3D movie released, it was hyped to an extent where people got amazed with such a technology that had been used. But now, the latest developments over the visual dimension have extended to 5D and 7D. The technology hasn’t showed its magic only in the field of cinema, but added up in to various areas, such as mobile phones, gadgets, TV’s, computer and laptops, cameras and so on.

Now that the people are so used to live and survive with the technology, they always want more from them, and even the techno creators don’t disappoint them in any sort. They keep innovating new things which would make the world a better place with ease of accessibility.

We all know that every new technology is competing with their existing technology, in cameras, the race of Megapixels, in computers, the race of Megahertz (MHz), from phones to smartphones etc. The world is changing from projectors to HD television, from basic calling to video calling, from normal chatting to instant messaging, so what makes TV behind, and that’s how they have come up with the latest improvisation of 4K aka Ultra High Definition taking over all the other HD video compilation.

The push for better pixels is on demand due to such innovation of larger television by various brands needs to be compiled with better pixelate screening, 4K aka Ultra High Definition fulfils the need.

Let’s get started with the resolution of 4K aka UHD, it is said earlier that 4K had been found years back and its resolution was somewhere between 4096 x 1744 and 4096 x 3072 pixels (it’s almost equal to 10 standard aspect ratio) but technically, the multiplex screen resolution is 4096 x 2160, however, 4K has a little lower resolution compared to multiplex ranging from 3840 x 2160.

You can clearly see the difference by experiencing and comparing the same visual in HD and as well as 4K, it is obvious that 4k would have much sharper image and as well as the picture clarity with details.

However there is a saying, the more you get the more you want and usually it is considered to be better. Though we have seen the positive side of 4K, let’s get you all to the digital muffs on 4K aka UHD which can be more perplex than you can ever think of.

Netflix and YouTube are the two largest online services which are providing 4K streaming videos online. Many 4K TV’s will automatically support the Netflix via Ethernet connection, however the services are restricted to a limited number of movies or shows which are of 4K aka UHD. To experience the real quality of 4K aka UHD you need a sturdy internet connection with download quota for taking the benefits out of 4K aka UHD.

Netflix download quota gives up to 15.5 Mbps and recommends taking an internet plan which gives you 25 Mbps for streaming and downloading 4K videos. If you are just streaming online or watching a movie online make sure you have enough backup of GB’s to proceed further with your internet plan, as a two-hour 4K movie from Netflix can eats up the size upto 18 GB, and a total of 13 episodes TV series can astound around 117 GB.

It is little complicated for those who would like to stream videos on Netflix because it can support only if you have HEVC code and as well as the certification from the Netflix itself for the devices to playback.

If your TV doesn’t support the Netflix compatibility, you can get hitched on home theatre PC to your TV and to cross-check whether the video card support the HDMI 2.0, so that you’re not restricted to stream up to 30 fps (frame per second) video.

The main advantage of having a HTPC is that you can stream videos on YouTube as well as connect to your TV. It needs a lot of understanding to connect the route Foxtel through your HTPC, if it is possible.

The other available option through which you can stream videos on TV is by purchasing the existing android based 4K compatible mini PC’s such as Minix and Neo X8-H Plus. They can give up the quality resolution up to 1080p.

4K compatibility towards Xbox one is impossible to stream and PlayStation 4 can support up to 30 frame per second by giving us only HD resolution. There has been a talk going on that the software would be upgraded to HDMI port 2.0 by this year, which enables to stream videos from Netflix and as well as local videos.

4K aka UHD Blu-ray discs will be released by the end of this year, the discs are compiled and encoded with the newer version of HEVC/H.265 codec (High Efficiency Video Coding) which is said to be the most prominent way of compression. This ameliorate compression can hold up to 25 GB/50 GB/60 GB or may extend up to 100 GB. This upgraded Blu-ray discs would support the visual with a better colour contrast, high frame rate speed, and a broader colour spectrum.

Everybody, in near theatres would have experienced Dolby vision which is nothing but HDR (High Dynamic range) which plays with the shades and colours of the frame. All the latest brands like, Sony, Samsung, Phillips, Panasonic etc have announced their standard for HDR.

Primarily, HDR movies or HDR screen brings out the most realistic frames to the audiences with its better colour contrast and defines the thin line between the darker blacks and brighter whites, and also showcases a wide spectrum of colours can also be identified.

The most difficult dare for Blu-ray is to survive in the current market which is totally hooked into online streaming services, unless and otherwise they don’t get what they are expecting, the market for such launch is finished.

Let’s wait and watch for the updates.
