The 4K Path of All People Explains the Development Path of High-Definition Players

4K is an unfamiliar and familiar concept. Since there are special glasses during 3D viewing, the effect of true 3D display really stimulates the visual, but 4K is a viewing experience that is not easy to express in words. Compared with nouns such as 1080p, 720p, and 2K, what is the charm of 4K?

4K can be understood as 1024 × 768 × 16 or 1920 × 1080 × 4, the screen is more clear, you can display more of the screen content or details, the clear picture is already the biggest temptation to the user, think about a single technology Ascension allows you to enjoy 4 times clearer images. This temptation is undoubtedly fatal.

So why is the rapid development of 4K display technology in the near future and why is it so urgent for users? Is it just because it can provide a clearer display? Of course, the answer is no, then we will decrypt it.

4K forced to cut demand interpretation

So what is the current 4K technology so favored by users? Why 4K must be the future trend of development? This has to say that the TV size has changed.

It can be seen that the current TV size is growing rapidly. 27-inch TVs have been considered very large 10 years ago, and now 65-inch-plus video frequency appears in the living room. Users who buy large-size TVs will surely find a problem. Although the screen size is large, the display effect is not as clear as before.

That's right, because the limitation of resolution, especially the resolution that cable signals can provide is very limited, resulting in serious graininess of the picture, but the big TV has no better results. This is the direct reason why 4K was forced to cut demand. Some people may say that 1080p is already pretty good. It may be that you haven't watched the shock of 4K resolution, or it may be that your TV is not "big."

This is why 4K technology is currently developing at a rapid rate. Although it is still not mature in terms of resources, it is undeniable that 4K will definitely become the long-term development direction until its maturity. The reason is very simple. You can't expect users to switch their big TVs to small color TVs.

4K decoding you may not know

Unlike before, 4K can be played directly without a 4K panel. To put it simply, for now, the 4K source is required to be decoded for viewing. Since the 4K file is too large, it needs to be compressed before it can be used conveniently. Therefore, the inverse operation of decoding when we watch is inevitable. . If it comes to 4K decoding in two ways: hard decoding, soft decoding.

In general, the high-definition file has a very high compression rate, which requires the box to provide a large amount of computation to decode the resource. Once the CPU cannot be used to provide the operation rate, the decoding process is a soft solution (which affects the box. The normal use of the performance may not be reflected in time, it is prone to hot.

The hard solution is referred to as hardware decoding. It does not provide computational power through the CPU, but instead derives power from special chips, such as GPUs, freeing up the performance of the CPU to make the box run more smoothly, and it can also perform its job perfectly. , Deal with big data, if the technology is up to standard, the compatibility can also be improved, and it can help to decode more high-definition video formats.

It is already clear from the above explanation that the difference between hard decoding and soft decoding is that soft decoding is performed by computing, and the heavy work of decoding is attached to the hardware. The hardware is under tremendous pressure and will have an impact; but special chips are used for decoding. The task will be carried out independently, hard decoding is definitely advantageous.

High-definition box closer to 4K is an inevitable trend

As a high-definition set-top box that has become the mainstream companion of TV, support for 4K must be the trend of the future, because counting on TV to achieve 4K decoding is somewhat difficult. So the high-definition set-top box to provide support for 4K broadcast TV provides a very good decoding capability has become the future direction of development.

As already mentioned, hard-to-decode 4K is the best solution. Relying on the GPU's powerful execution capability to achieve decoding will not cause too much burden on the CPU in the HD set-top box. Fortunately, there have been such products in the market. The first batch of JCs R11 and millet box enhanced versions have entered our field of vision.

Semi-future state millet

It's nice to see that vendors have spared no effort to narrow the distance between their products and 4K. The set-top boxes using Amlogic S802 high-end solutions can already achieve 4K hard decoding. It is also necessary to choose such a product. As a simple example, this World Cup will have a 4K game released, with Caton's football game, which fans can tolerate?

Future shows should be like this

There are products that support 4K. We should definitely give priority to selection. Products that meet the trend can often save us a lot of money, at least for a period of time without investing in upgrading HD boxes. Millet's current taste of some futures, production capacity problems exposed so many people holding bills waiting obviously inappropriate; Fortunately, we can also choose Jieke R11, is the development of the blowout period of 4K, for a 4K TV with a box without delay.
