The layout quietly unfolds on the future of 8K resolution technology

At the IFA 2017 show in the past, Sharp’s 70-inch and 85-inch 8K resolution televisions were unveiled, and overwhelming reports followed. In fact, as early as 4K TV was just released, Sharp displayed an 85-inch 8K resolution TV product at the CES 2013 in the United States. After 4 years passed, is the 8K resolution technology mature? Is the 4K resolution just starting to die? ● 8K technology is a milestone We now have a large housing area, TV size is also large, 50-inch, 60-inch to 70-inch TV with full HD resolution, granular pixel is obvious. Unless you are watching more than 4.5 meters away, how many living rooms or bedrooms can there be? After coming to 4K resolution, this issue has been significantly resolved. In the face of 4K resolution, all of us were shocked. This resolution is too delicate. As long as the distance is more than 2.7 meters, we can make the graininess disappear. Many "experts" think 4K is the pinnacle of display clarity.
Then, 8K technology came. The 8K resolution is 4 times the 4K resolution. In the same size, the viewing distance is reduced to within 68 cm to see the graininess. The size of our average family living room, sofa to TV how to get close to 2 meters away from it, that is, you can completely eliminate the grainy feeling, watch the feelings of improvement, and more eye protection. If the 8K resolution is applied to smaller screens and laptop screens, then the normal distance will not see the graininess of the pixels at all. In other words, 8K display devices will make us truly visually immersive.
Imagine that the television from the cinema to the home in the next few years will be an 8K technology viewing experience. It is undoubtedly a visual feast. However, I believe that 8K is just the technology of our time, just like the development of mobile phones and computer hardware. In the next era, as the entire industrial chain continues to develop, 8K technology will also be replaced, just like the now tepid 4K. However, 8K technology is definitely a very important milestone.
● 4K is faster than Full HD. What about 8K?
Friends who often pay attention to real-world devices may be quite clear. Whether they are TVs or monitors, the resolution from full-HD 1920X1080 to popularity has been used for nearly 10 years. It can be said that the road is long and rough. However, it took only 5 years to transition from Full HD resolution to 4K resolution. Since 2014, 4K has had a blowout-type explosion on televisions, monitors, and video recording devices, and it is now highly sophisticated.
8K? Although there have been product demonstrations in 2013, 2017 is the first year of 8K. However, in order to popularize 8K, the current layout has only just begun, and the supporting industrial chain and application chain have only begun. I believe that at least until after 2020, we can begin to talk about 8K popularization. Maybe the 2020 Olympic Games and 5G mobile technology will assist the popularization of 8K technology. When everything is ready, I believe that the popularity of 8K technology will be faster, perhaps 3 or 4 years is enough.
● 8K technology is close to us. Many people will think that this year is the 8K first year, then 8K should be far away from us? Just like 4K just appeared. Actually not, from the upstream 8K video recording equipment to the 8K terminal playback equipment, mature products have come to consumers. It is now only supported by mobile network technology that supports 8K video transmission.
Everyone knows, Marvel's movie "Guardians of the Galaxy 2" was shot with 8K camera technology, but at present the theater is still unable to support 8K video playback, so it is compressed to ordinary resolution screening. Sharp recently used 8K technology to broadcast to the Chinese media the boxing champion Zou Shiming's game, the effect was very shocking. In addition, Japan’s NHK TV has repeatedly broadcast live sports games under 8K technology. Seemingly from full HD to 4K, and then to the application of 8K technology on TV programs, Japanese TV stations have always been ahead of the world and have been vigorously promoted.
Seeing these mature application experiences around us, do you think 8K is still far away? However, I feel that 4K technology is now "Alexander".
Although only Sharp has released its 8K technology display device, in fact, the entire industry layout of 8K technology has already begun. The famous Foxconn Technology Group is also promoting and participating in this matter.
● Foxconn promotes 8K development Although 4K technology is still tepid, the 8K layout has begun quietly. To intervene in an emerging technology industry and get the right to speak, it is natural to begin to lay out the entire industry in the early days of technology. Foxconn Technology Group was previously reported to set up a film and television company to invest in film and television content products. In other words, Foxconn Technology will deeply participate in the photography of the upstream and the TV products of the terminal in the big industry that promotes the development of the 8K technology.
In order to allow 8K television to arouse public interest and purchase, Foxconn is necessary to get through all aspects of the industry. That is to say, from the content output, content dissemination to the terminal equipment must take into account, so that consumers will buy it, otherwise we have an empty 8K TV, there is no 8K content playback, buy what significance? For shooting products, currently JVC Super Hi-Vision cameras can record 8K video. It is rumored that it will launch an 8K camera at the end of 2017. It was jointly developed by Sharp and Japanese image equipment manufacturer ASTRODESIGN. It is said that the entire device weighs only 5 kilograms and is no longer a monster. That is, the video content of the future 8K technology will naturally be more and more.
Although the layout has already started, it still needs time and more cooperation opportunities to achieve. Therefore, if we really enjoy the content of 8K technology at home, it will still take some time.
● 8K changes to the industry and applications The emergence of 8K technology, due to its extremely fine resolution, has brought about a very significant change in some of our highly mature industries. The most significant and significant examples are street surveillance cameras and medical equipment.
Do you still remember the "celestial eye system" in the movie "Speed ​​and Passion"? It is through the ultra high-resolution camera full of street to carry out face recognition, and then search for the hiding place of criminals. It is not very future, but in fact there is already a similar device in use in Chicago in the United States. The number of security surveillance cameras in the city is very rich, but the accuracy of the face recognition, the current camera resolution is still too low. Therefore, if the camera is replaced with an 8K resolution in the future, there will be better protection in terms of security, so that criminals can no longer hide, and the efficiency of search and arrest will also be significantly improved.
Another area in which 8K technology is best applied is medical treatment. Current endoscopic surgery is performed by doctors using robots and cameras. However, the accuracy of current cameras is still not high enough. In the future, with 8K technology cameras and display devices, the operation and precision of the surgery will be greatly improved, allowing more patients to recover sooner. In addition, 8K display devices are used in the medical field to allow doctors to see clearer cell-level images and diagnose whether the tiny shadow on the X-ray film is a cancerous tumor. The future 8K technology and equipment will provide a better platform and support for the development of our medical care.
Of course, there are certainly more than two applications for 8K technology. For example, our future work life, education life, entertainment life, family social life, green car life, property transaction procurement life, healthy life, and safe life, 8K technology will infiltrate and participate in among them. The author believes that science and technology not only change life, science and technology can also improve life and make our life better in all aspects.
What is the current development dilemma of 8K technology? One is the source problem. Currently recording equipment and terminal display equipment are gradually maturing. This dilemma has been gradually resolved; the other is the issue of product price, which we have in the next page. Everyone has an in-depth discussion; the last is communication, which is the problem of speed and bandwidth.
● Internet speed is the bottleneck of viewing 8K video. Consumers are no longer restricted to TVs for daily entertainment viewing. Mobile, tablet PC hardware platforms such as Youku, iQIYI, and Tencent video are the youngest players. In the mainstream entertainment model.
In fact, the broadcast of 8K TV signals has already been tested by Japanese NHK TV stations as pilots. At last year's Rio Olympic Games, NHK TV conducted a live broadcast of the 8K format for 130 hours and was very successful. And NHK TV station also stated that at the 2020 Tokyo Olympics in Japan, people can watch 4K and 8K live broadcasts, but as for whether or not there is a corresponding display device, then another said.
The trickiest part is still playing this part of the Internet. Whether it is fiber-to-the-home broadband or mobile networks, currently playing 8K video is a matter of speed. Well-known foreign well-known websites such as YouTube (Tube) and Netflix already have 4K sources. I have experienced several times before, but the long read cache time allows the author to directly give up each time, not to see any A complete video. Now, the 8K format "Ghost Towns" is also available on YouTube. However, on the one hand, Big C has no equipment. On the other hand, the speed of the Internet over the wall is unbearable, so it has not been experienced.
How big is the 8K video? Previously recorded in 8K format with Super Hi-Vision cameras was only 1 minute in length, taking up 194GB of storage space. Even if the video stream is compressed on the network, the video stream is still a horrible size. What kind of speeds do we need to cache 8K videos in real time? I do not know whether the telecommunications 200M fiber home in the home can be real-time cache playback.
● Real-time transmission of 8K video relies on 5G?
According to the barrel principle, the resolution is always the short board in the barrel. If the resolution is improved to the 8K level, it is bound to require more significant improvements in other long boards, such as speed, set-top box, video recording, and so on.
We are now the most popular is the live broadcast, the conference will be broadcast live, go live to play live, introduce products to live, and live more and more outdoor, reliance on the mobile network is increasingly evident. At present, the quality of the live broadcast is still rather poor. In order for everyone to see clearer results, the live broadcast format will inevitably gradually transition to 8K resolution.
As the resolution of live broadcasts increases significantly, the pressure on mobile networks will increase. The current 4G mobile network transmission speed can be honest, but for live broadcasting, the real-time bit rate is only about 20MB. In other words, the best picture quality that currently depends on the mobile network for live broadcasting can only reach the Blu-ray DVD level (25 MB bit rate), and it cannot be broadcast in real time. So the current solution is to broadcast live and download in real time and then watch offline.
In the present situation, the only expectation is the popularity of 5G mobile network technology. The 5G mobile network technology will enter the experimental stage at the end of this year. In theory, the transmission speed is 40 times that of 4G technology. With such a speed, there is no need to worry about the 8K broadcast.
Of course, 5G technology is not just to help 8K video to solve the live broadcast problem. If it can really achieve the theoretical speed value of this test, then the major video sites will have further significant development, after all, high quality and high resolution. Video can be transmitted in seconds. At that time, the quality of the video we watch on mobile phones, tablets, and computers will also increase significantly. Even if we do not have 8K devices, the quality of the video we watch on ordinary devices is a qualitative leap.
However, at present, the popularity of 5G technology also needs to wait at least until 2020. The Olympic Games may be the outpost and opportunity for the popularization of 8K+5G technology.
However, at present, some film and television companies are also actively looking for better coding techniques to help 8K video compression and use less bandwidth.
Talking about the layout of the 8K technology and the transmission problem of the 8K technology, we will talk about the 8K technology and the consumer market. This involves one of the obstacles to the current popularity of the 8K technology and the price.
● When can 8K TV enter the home?
Now the 8K resolution consumer market, 8K TVs and 8K monitors have come to consumers, but the 68888 yuan sharp price of Sharp 8K TV is indeed unacceptable to consumers. Foxconn actually understands this problem, but it is still a very difficult path to reduce the price to a level acceptable to consumers.
For 8K TVs and monitors, anything related to the screen is related to the panel. There is a yield problem at the beginning of any panel specification change. Designing 8K resolution in the same 70-inch panel is far more difficult than Full HD or 4K resolution, which is more than a four-fold relationship. So the current cost of the panel is very high, which directly affects the price of the TV.
In addition, only 8K TV Sharp has released its mature 8K resolution panel products, South Korea's Samsung SDI, LG Display, China's BOE, Taiwan's AUO and so on panel makers have not yet issued a voice of response. Only the competition can make the selling price of the product drop quickly, so I also expect other internationally renowned panel manufacturers to follow up and share the big cake of the 8K market together. Only the entire upstream and downstream industries have been brought up to allow the industry to grow and compete, so that consumers can enjoy affordable products.
The author believes that 2017 is the first year of 8K technology, so next year is the year of 8K technology. 8K TV really can enter the consumer's home, it should take at least 3 years, that is, after 2020.
● At the end I believe that the entire 8K ecological system needs to play its own role in all aspects so that it can promote the 8K technology industry development. For example, pre-recorded video, clips, storage, mid-term video conversion, distribution, terminal display devices, these links have played a role in this, it can help the rapid development and popularization of 8K industry.
Now Sharp has launched 8K resolution products related to televisions and monitors. Because of the technology and screen production capabilities, it is not difficult to develop laptop screens and screens for mobile phones in the future, so that the entire 8K horizontal product line layout can be improved. For the popularization of 8K in the consumer-grade market, it has greatly promoted and helped.
In addition, currently game companies have begun to add support for 8K resolution screens in their games; 8K video content is also becoming more and more abundant; driven by NHK TV stations in Japan, TV broadcasts for 8K signals will gradually increase. When we can afford 8K TVs and monitors, our application entertainment content has accumulated accordingly. Compared with the early stage of 4K technology popularization, 8K technology has more and better content foreshadowing.

Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
