When it comes to 8K TV, we must distinguish between its application on TV and 8K technology itself. It is inevitable that any technology is moving forward, and 8K TV is facing the general mass consumer market. The issues that need to be considered may be more complicated.
On August 31, Sharp officially released the world’s first consumer-grade 8K TV, which sold for 68,888 yuan. In 2015, Sharp also launched an 85-inch 8K TV with a price of over 850,000 yuan. Although Samsung, Skyworth, Hisense and other domestic and foreign manufacturers have also shown their 8K televisions at major electronics shows, only Sharp has really pushed for it.
8K TV may be more ambiguous than 4K TV
8K TV is the most direct improvement in the clarity, the current 4K TV resolution is 3840 × 2160, about 8 million pixels; and 8K TV resolution of 7680 × 4320, about 33 million pixels, about 4K TV 4 times. Sharp official said that the best distance for a 70-inch 8K TV is 68cm, but I really don't think it would be a good experience to see a 70-inch TV from a distance of 68cm.
If only from the aspect of product strategy, 4K TV is now universally popular, 8K TV is an inevitable trend. Sharp's first release of consumer-grade 8K TVs has captured the dominant position in the competition for the future 8K TV market. But thinking about the current situation of 4K TV, people feel that it is too early to talk about 8K TV.
Technology is always ahead of the market. When 4K TV was first introduced, it was controversial. Due to lack of resources, 4K TVs are useless, and we know that we haven't stopped them yet. However, 4K TVs are still forced to open because all TV companies are trying their best to attack 4K TVs. Still, some 1080P TVs are only available in sizes 43 and even smaller. On television, consumers have almost no choice.
In this trend, the global video industry has begun to vigorously develop 4K video, the most representative is the United States Netflix, domestic Youku Tudou and Huawei also launched 4K gardens to create high-quality 4K resources. But judging from our daily experience, 4K video resources are rare. Not to mention that China's cable TV signal high-definition still stays at the highest level of 1080i, and even the standard brick 1080P is not reached.
The popularity of 4K and 8K technologies can't be completed in 2-3 years. From shooting, production, transmission to playback, these arrays of technologies and equipment all need to be replaced. However, 4K currently only solves the problem of playback devices. However, in the limitation of transmission bandwidth, 4K video can benefit from the birth of the H.265 encoding. The 8K video will obviously face such difficulties again. Otherwise, if the standard 8K video exceeds 100G in one minute, even if the storage space is sufficient, most people's network conditions cannot withstand it.
Even Japan, which claims to popularize 8K TV signals in 2020, was only the first trial broadcast last year, and set up a few visiting points for users to enjoy because ordinary users cannot afford the high prices of 8K video playback devices.
For the current development of the television industry, resolution is not the most need to improve at present, but 4K has been somewhat ahead of the time, in the content also need to desperately catch up. The author is more concerned about the visual effects that OLED or Quantum TV can bring.
8K technology far exceeds TV in professional field
8K TV may be very embarrassing in the general consumer field, but it is really needed in the professional field. For the simplest example, videos shot using 8K technology can be cut into 4K or 1080P at random, which can greatly increase the efficiency of the shooting process.
The number of 8K video frames will be up to 120 frames, and currently 4K video generally only supports 60 frames. In the Brazilian Olympics, the 8K event live broadcast for the first time, 8K picture can capture a more detailed picture, swimming can clearly see the splash of water when the arm strokes, demeanor when the big mouth ventilation, if with VR equipment Really close to the scene.
In addition, the application prospect of 8K technology in medical treatment is also worth looking forward to. In many major surgeries, some parts cannot be seen with the naked eye, and with the aid of a medical microscope, 8K imaging technology can present a clear picture and reduce the difficulty of surgery to some extent.
The application of 8K technology in professional fields even far exceeds the value as a TV or other consumer electronics products, and has gradually been put into use in various fields. Even if 8K TV is an inevitable development, it is still too early to take this step.
