Recently, 4K TV has attracted more and more attention. Just as 1080p and 3D had just come out, manufacturers would spare no effort to promote it and naturally some people would sing. The reasons for bad luck are nothing more than "4K sources lacking" and "4K TV can only be bought as ordinary TV." If we look at old products and old technologies, we can use this point of view to make sense; but the times are advancing, with the introduction of new technologies and new products, and fresh blood in the 4K industry chain. As we enter, we may wish to take a fresh look at 4K. So we will find that 4K is not so far away from us as we thought.
I often discuss some current 4K situations with friends around and in the network. The following summarizes some of the frequently misunderstood 4K TV and 4K industries for you to share.
"4K TVs are expensive"
The 84-inch 4K TV first introduced by Sony and LG in the previous year was priced at RMB 180,000, which really frightened many consumers. However, this kind of machine is actually expensive in the "84 inches", rather than expensive in the "4K", Imagine even a 1080p 84-inch TV prices will not be cheap where to go.
After entering 2014, with the mass production of 4K LCD panels, the 50-inch medium-size 4K TV has dropped to the same level as 1080p. For example, Skyworth’s 50-inch 4K TV has sold for five or six thousand yuan. Emerging brands such as LeTV and Lenovo have pulled the price to below 4,000 yuan.
"4K content scarcity"
Buying a 4K TV but not seeing 4K content is indeed a difficult problem at present. However, 4K content is not really "deficient". What really lacks is the distribution channel of 4K content. Traditional channels include television stations, Blu-ray discs, and the like, but so far there has been no 4K television channel in the world, and no 4K Blu-ray disc has been introduced. This time, the Internet has taken the lead. Netflix abroad has broadcasted the 4K House of Cards. Youtube also supports 4K. In China, online video companies such as LeTV, BesTV, Ulead, and Sohu Video have launched or 4K network content is being planned.
On the other hand, with these 4K distribution channels, 4K content will spring up in abundance. There are currently some of the following sources:
1. A large number of traditional film movies can be converted into 4K digital format, quickly solving the problem of lack of 4K content;
2. Use 4K digital video cameras to film movies, TV dramas, variety shows, sports events, etc.;
3. Computer-composite CG animation movies can be directly output as 4K digital format.
"4K video files are too big to store"
Searching the Internet for 4K test data from institutions such as NHK in Japan will give a huge impression on 4K video files. But that is only the case in professional equipment and certainly not in the civilian environment. Solving the problem of 4K video files consuming storage space mainly depends on new video encoding formats. Currently the most popular is the H.265 format, and Google's main open source format VP9, ​​both of which can video files under the same picture quality. Shrink to half of the traditional H.264 format.
Basically, it can be assumed that a 4K movie in H.265 format occupies almost the same storage space as a 1080p movie in H.264 format; or slightly larger, it can be loaded with an existing Blu-ray disc. Recently, Sony and Panasonic have jointly introduced a new disc format Archival Disc. The single disc storage format can easily reach 300GB to 1TB. It should be to solve the 4K or even 8K storage problem.
"See network 4K video bandwidth is not enough"
This is similar to the previous problem. If you use the old H.264 format, the network 4K video will occupy an astonishing bandwidth, and the cost pressure on users and service providers will be huge. However, with the new H.265 format, the problem is solved. The author found at the conference of LeTV X50 Air that the network bandwidth occupied by the 4K video in the H.265 format is 10M, which is the same as the previous 1080p video in the H.265 format. The 10M is an entry-level fiber-to-the-home, as long as it is home to consumers with fiber broadband, can enjoy smooth 4K network video.
"It doesn't make sense to watch 1080p movies on 4K TVs."
At first glance this question is indeed, a lot of HD enthusiasts have a lot of 1080p full HD movies in their hands. Is it a bit too awkward to use 4K TV? In fact, every manufacturer will use some video enhancement techniques for 1080p in 4K TVs. Watching 1080p videos on 4K TVs will be more delicate than viewing on 1080p TVs.
"No game support 4K"
The author saw this statement on a well-known blog: "At present, most game consoles output up to 1080p, and this resolution uses 4K TV in excess." Maybe what he said was the PS3 and Xbox 360 launched before 1989, but the PS4 and Xbox One that were released at the end of 2013 clearly supported the 4K output, but there is currently no game maker to launch 4K games on these two platforms. As for the future there will certainly be.
Not to mention computer games. Last year on ChinaJoy, we saw NetEase demonstrate a 4K online game "Crisis 2015" with a Sony 4K TV. Hardware technology progress so fast, 4K TV has, 4K games will be far behind?
Crisis 2015
To sum up, after entering 2014, the entire 4K ecological chain has become more mature, and as usual, only traditional TV makers are alone there. It is believed that as the 4K concept and 4K content increase, the public will know it more accurately. At present, there have been a number of very cost-effective 4K TV products, the timing of the purchase of 4K TV is also basically mature - of course, we must pay attention to the selection of advanced technology models, in this regard music as the TV X50 Air represented 2014 The new product not only supports H.265 4K decoding, but also provides a 4-core high-performance processor, which is the first choice.
Note:
4K is the next-generation TV resolution standard. It refers to the resolution of 3840×2160. Its resolution is exactly four times that of 1080p Full HD, so it is also called “Ultra HD†or “UHDâ€.
