More and more attention has been paid to 4K TV

Absrtact: The recent 4K TV more and more attention, like the original 1080p and 3D just out of the same, manufacturers in spare no effort to promote, naturally people will sing.

Recently, 4K TV more and more attention, like the original 1080p and 3D just out of the same, manufacturers in spare no effort to promote, naturally people will sing. The reason for the failure is no more than "4K source shortage", "4K TV can buy only when the ordinary TV watch" and so on. If based on old products and old technology, in the old view, this argument is reasonable; but the times are moving forward, with the introduction of new technologies and new products, as well as the 4 K industry chain of fresh blood, we may wish to look at 4 K with a new perspective. In this way we will find that 4K is not as far away as we think.

I often with the side and the network friends to discuss some of the status of 4K, the following summed up a number of frequently encountered in the 4K TV and 4K industry misunderstanding, for everyone to share.

"4K TVs are expensive."

Sony and LG, the first to launch the year before the year 84-inch 4K TV price of up to 180,000 yuan, really scared a lot of consumers. But this kind of machine is actually expensive in "84 inches", not expensive in "4K", imagine even a 1080p of 84-inch TV price will not be cheap to go.

After entering 2014, with 4K LCD panel production, 50-inch medium sized 4K TVs have fallen to the same price as 1080p. For example, Skyworth's 50-inch 4K TV to sell to five thousand or six thousand yuan, emerging brands such as music, Lenovo is to pull the price to 4000 yuan below.

"4K content is scarce"

Buying 4K TV but not seeing 4K content is a real problem at the moment, but 4K content is not really "scarce" and what is really scarce should be the distribution channel for 4K content. Traditional channels have TV stations, Blu-ray discs and the like, but so far the world does not have a 4K TV channel opened, nor a 4K blue disc launched. This time on the contrary is the internet walked in front, the foreign Netflix is the first broadcast 4K "card House", YouTube also supported 4 K, there are music in the country, hundred-Vision, gifted peer music, Sohu video, such as network video company launched or planning 4K network content.

On the other hand, with these 4 K distribution channels, 4K content will soon springing up, there are mainly the following sources:

1. A large number of traditional film films, can be transformed into 4K digital format, quickly solve the problem of the lack of 4K content;

2. The use of 4K digital video cameras to film, TV, variety shows, sports events, etc.

3. Computer-synthesized CG animated films can be output directly to 4K digital format.

"4K video file is too big to store"

On the network search Japan NHK and other institutions of the 4K test data, will give a huge impression of 4K video file volume. But that is only the case of professional equipment, in the civil environment will certainly not be like that. To solve the problem of 4K video files occupy storage space is mainly rely on the new video coding format, the most popular is the h.265 format, the other is Google's main push open source format VP9, both can be in the same quality of video files to reduce the traditional H.264 format half.

Basically, a 4K movie in a h.265 format takes up almost as much storage space as a 1080p movie in H.264 format, or slightly larger, with an existing blue disc. Recently, Sony and Panasonic jointly launched a new CD format archival Disc, the single disk storage format easily up to 300GB to 1TB, should be to solve the 4K or even 8K storage problems.

"See network 4K Video bandwidth is not enough"

This is similar to the previous question, if the old H.264 format, network 4K video will occupy a staggering bandwidth, the cost of users and service providers are very high pressure. But with the new h.265 format, the problem is solved. The author in the video tv X50 Air press conference found that the h.265 format 4K videos occupy the network bandwidth of 10M, and the previous h.265 format 1080p video. And 10M is the entry level of fiber, as long as the home has fiber-optic broadband consumers, can enjoy the smooth 4K network video.

"It doesn't make sense to watch 1080p movies on 4K TV."

The problem at first glance is indeed, many HD enthusiasts hand tun a large number of 1080p Full HD movies, used on the 4K TV to see if it is a little too stifling? Virtually every vendor will be able to apply some of the 1080p-quality improvement techniques to 4K TVs, and watching 1080p on 4K TVs is a bit more nuanced than watching a 1080p on a TV.

"No Game support 4K"

The author in a well-known blog to see this saying: "Most of the current game machine output up to 1080p, such a resolution using 4K TV is really superfluous." Maybe he said eight or nine years ago launched the PS3 and Xbox 360 bar, but the 2013 end of the listing of PS4 and Xbox One clearly labeled Support 4K screen output, but there is no game maker to launch these two platforms 4K games just, as for the future will certainly have.

Computer games is not to mention, last year's ChinaJoy we saw NetEase with a Sony 4K TV in the demo of their own 4K network game "Crisis 2015." Hardware technology progress so fast, 4K TV have, 4K game will be far?

To sum up, is to enter the 2014, the whole 4K ecological chain is more mature, no longer as usual only the traditional TV manufacturers in there clap. It is believed that with the 4K concept and the increase of 4K content, public understanding of it will be more accurate. And there have been a lot of cost-effective 4K TV products, the timing of the purchase of 4K TV is also basically mature-of course, choose to pay attention to the selection of advanced models.

Note：

4K is the next generation TV definition standard, it refers to 3840x2160 this resolution, its clarity is exactly 1080p Full HD four times times, so also known as "Super HD" or "UHD".
