Just as 4K refers to 4K resolution, 8K naturally refers to 8K resolution. The specific pixel size, the former can reach 3840 × 2160, while the latter is more exaggerated, reaching 7680 × 4320. 4K TV to our current point of view, the smallest size of the market has also been quite large, 8K then With high resolution, the allowable screen size is really hard to imagine.
The vast majority of people have not yet entered the 4K era. However, the investigation agency Juniper Research has published a research report, saying that 8K will soon become popular in 4 years, that is, in 2020! The reason why they think so is because Japan’s NHK TV station has already decided to adopt 8K broadcast in the 2020 Tokyo Olympic Games. Analysts believe that this will push the market towards higher resolution.
More exaggerated, researchers predict that between 2020 and 2021, shipments of 8K smart TVs will quadruple, eventually reaching 400,000 units per year. When we see this, we will always feel somewhat unrealistic. After all, there are only 4 years left until 2020, and 1080p is still the absolute mainstream. 4K products have only just entered development acceleration this year.
So, how should we look at this 8K resolution that seems to soon become mainstream?
8K "Bright eyes"
As mentioned above, the 8K resolution can reach 7680×4320 pixels, and the number of pixels exceeds 33 million, which is 16 times that of our most common 1080p resolution today. Applying this resolution to your TV allows you to obtain a very clear picture even with a very large screen size. The benefits brought by the clear picture need not be said. No matter if it is a small change in the expression of a character or the effect of small particles such as smoke or dust, you can see clearly. This increase in resolution can make people feel more realistic and even more three-dimensional. What's more important is the increase in resolution. Even if the size of the TV becomes very large, the viewing distance it needs will not be very far away, which in a sense also reduces the demand for televisions for the room.
Don't look at 8K and 4K. There is a considerable gap in paper data. In fact, the technology they belong to does not differ from it, but it belongs to Super Hi-Vision. As early as 2006, the Japan Broadcasting Association's Science and Technology Research Laboratory submitted a preliminary plan for Super Hi-Vision technology to the International Telecommunication Union and the Society of Motion Picture and Television Engineers. Among them, the International Telecommunication Union has evaluated this technology as an available solution for Ultra High Definition Television (UHDTV) standards, and this is the beginning of 4K and 8K technologies—the former is UHDTV1 and the latter is UHDTV2.
If we say that there is no intergenerational technology, we can get even more amazing visual effects. The industry only considers 4K to be a halfway stop. It's no surprise that there is a steady move towards 8K. Unfortunately, things are not that simple.
8K is not good enough
In fact, since 2015, major manufacturers have begun to push 4K technology; by 2016, they are also using software and hardware to work together to launch a three-dimensional offensive against consumers. However, the industry still does not believe that 4K TV can immediately become mainstream, and too little content is a major cause.
From this year onwards, 4K Blu-ray movies have arrived on the shelves, but their number is still far from enough compared to the massive amount of traditional 1080p Blu-ray movies. Not only 4K TV, 4K Blu-ray player development has just begun, there are only a few devices on the market (if we still count on Microsoft's home console Xbox One S), and the price is not particularly close to the people . In addition, the vast majority of TV stations still cannot achieve the 1080p standard. As one of the most frequently touched TV content, this is a big problem.
The content of 4K is advancing so slowly. When manufacturers want to promote 8K, the difficulty is bound to be even higher.
The first is that the film source is too small. We have already mentioned that the number of pixels in the 8K resolution exceeds 33 million, and most of the photographic equipment and even full-frame SLR cameras on the market are only about 24 million. Even if you are playing a still photo, you cannot meet the requirements, let alone video. Compared to this dilemma, 4K technology is at least ridiculous in photographic equipment, and the difficulty is reduced a lot.
Another major obstacle is storage. It is understood that even if the video in the 8K format is only one minute, it can occupy a space of 194GB because of its excessive amount of information. Even Blu-ray Disc, the demand for such a huge storage space can not cope with. Blu-ray discs can not, it goes without saying that traditional television signal transmission and network transmission. The amount of information that is too large is incommensurable with the current technology. Although satellite transmission is a relatively good solution, it can only be used on large-scale projects such as the Olympic Games broadcast and cannot be used by ordinary consumers.
It is precisely because of this difficulty that it is still producing 8K TVs, and investing it in the consumer market is only the Sharp family. Sharp launched 8K TV LV-85001 last year, 85-inch TV up to 850,000 yuan, really is "inch ten thousand" ah. What's a pity is that the 8K resources are so lacking that we, the average consumer, don't think about it.
Of course, video encoding technologies such as H.265 and even H.266 can be used to reduce the size of the video. Future advances in all aspects can be expected. However, even if you think about it this way, making 8K resolution into the mainstream in 2020 is somewhat optimistic.
Not only the resolution in the future
Will there be 16K or even 32K after 8K? NHK gave a negative opinion. Some engineers stated that 8K is the ultimate resolution and will not be overtaken in the future.
From a certain perspective, experts' remarks are not unreasonable. As mentioned above, the higher the resolution, the more demanding the relevant peripheral technology requirements are. 8K's demand for shooting equipment and storage space is already quite high, and it is difficult to reach 16K. More importantly, experts say that 8K resolution is already the limit that the human eye can tell. It doesn't make sense to go up again. We don't need that big screen either.
In fact, in this 4K era, we should be able to realize that resolution is not everything. Of the technologies related to 4K, what is actually more important is HDR high dynamic range. HDR technology can make the brightness and darkness of the picture more vivid and show more details. It's certainly not enough just to increase the resolution. Color and light and shade are actually more important.
No matter what kind of resolution technology we will welcome in the future, we should not be in a rush to become fashionable. You know, resolution is not everything, the content and the beauty of the final image is the most important.
