The wave of intelligent technology is more and more surging. In recent years, the most talked about is the smart home, and the smart TVs in this area have revived with the sleeping giants, causing a huge wave of Internet technology. Last year, 10 Internet TV newcomers made their debut. Their common features are the banner of Internet content, the deep customization of the intelligent operating system, and the banner of fever performance and feelings. The only thing that made them shy away was the quality of the TV. Of course, each time they release new products, they will still spend a large part of their time talking about picture quality, and then they will say a lot of obscure terminology. They don't understand that people sound very tall, and people who understand can only silently bless.
Why do some manufacturers' video quality shy and tricky? In fact, when it comes to the most fundamental place, high-end panel technology and image processing technology are still a relatively monopolized field. Without a large number of technical R&D and product experience accumulation, it is impossible to achieve results. As newcomers who have just entered television, they certainly do not have the strength in this area, and the price of their products also determines the level of panel they use. What are the things that we often hear at the Internet televised conference? What are the quality technologies they call black technology?
I heard that this term is used by everyone
MEMC, Chinese name is motion compensation. Almost every time a manufacturer talks about the image quality processing part, the first one mentioned is it. However, we must disclose that MEMC is not a new black technology. The technology developed by Americans was adopted by Japanese color TV makers very early. However, most of them were used on high-end televisions at the time (this “high-end†was seized by certain manufacturers, but they were opportunistic. They were high-end TVs more than a decade ago, and they can still be counted), but in recent years, Most traditional TV manufacturers' products will use this technology.
In fact, this technology is indeed an important indicator to measure TV, and now everyone is constantly being brainwashed by the concept of "refresh rate", motion compensation is particularly important. To put it simply, MEMC uses algorithms to enhance the fluency of the picture. The original 24Hz video, after processing by the algorithm, reaches 60Hz or even 120Hz, so that the video content does not drag the hardware hind legs.
Earlier there was a similar technology called pull-up/pull-down. It can also increase the 30Hz content to 60Hz, but its approach is relatively simple and crude, but it simply changes the frame rate of 30Hz to 2 frames per frame. 60Hz, if it is 24Hz frame rate, the current frame is copied into 2 frames, and the next frame is copied into 3 frames. However, this method does not add new picture content to the video, and the quality of the moving picture has not been truly changed. The MEMC motion compensation technology allows the chip to self-predict what the next frame of each frame will be, that is, determine the motion trajectory of the dynamic picture, and then generate a picture frame that is not in the original video and is inserted into the original frame. .
Why use such technology? In fact, it is a wooden barrel principle, the hardware performance has reached the ability to decode 60Hz, and the signal frame rate of the transmission technology has also reached 60Hz, except for the content of the 60Hz content of the video content is very few. So even if you use a 60Hz TV, there is no corresponding hardware or the best results. This is just like you used a 4K TV, but there is no 4K source, watching SD video is still a reason. MEMC motion compensation can be said to be just a compromise, but the majority of program sources are shot at 24Hz or 30Hz. This technique has also become an essential tool.
However, even if many Internet companies use MEMC motion compensation, but most of them are 60Hz refresh rate, this of course will be cleverly hidden. Taking into account the cost, it is difficult to use the panel with a refresh rate of 120Hz, which also makes this technology a lot of useless. However, the real Japanese and Korean high-end TV, 60Hz is only the bottoming out standard, 240Hz refresh rate TV is also common. Of course, this refresh rate also seems to have a little metaphysical flavor. Many people say that the refresh rate that the human eye can tell is 24Hz. Why is it better to watch 60Hz video than 24Hz? Looking at 120Hz is more comfortable than 60Hz? This is also like Joe Bush think Retina is the limit of the human eye to distinguish the clarity, but when you see the 4K resolution notebook is still stunning.
Summary: MEMC motion compensation technology is an important indicator of TV picture quality. Xiao Bian feels that major TV manufacturers want to make it a standard technology known by passers-by, rather than used to trick marketing.
ARM chip and picture quality engine are not the same thing
The other thing Internet companies do now is advertise the hardware configuration of the product. Whether it is a mobile phone or a TV, it seems that they have embarked on this "fever" path. As a result, it was later said that only one meter of the most honest copy of the propaganda copy was "born for fever". What is a fever, under my understanding is the constant stacking of hardware, constantly stressed hardware parameters. It is true that in the early days of the development of smart TVs, the fluency of operations became its most inexperienced place. But now ARM chip technology has become more and more mature, and performance is no longer a bottleneck in the development of smart TVs. What is even more sad is that some vendors are stealing concepts and taking ARM chips to replace the image engine. What eight-core, 16-core processors consumers hear is overwhelming.
Now the makers of TV ARM chips are most likely to have MStar Morning Stars. The company that dared to single out Genie and Realtek Semiconductors is now on the TV chip. Of course, I was also used by irresponsible adjectives after being brainwashed by various vendors, such as quad-core processors based on the ARM Cortex-A17 architecture, Mali T760 MP4 quad-core GPU graphics chips, and H.265 hard decoding support. Performance is awkward. What is the use of such a processor? First, for Android system services; second, for video decoding services.
Of course, it also has something to do with quality. Because most of the TV ARM chips are also integrated with the image quality engine technology. For example, as shown in the figure below, 90 percent of the people will not finish reading the tall technical terms. Do not think that these technologies are very bovine, is what the TV manufacturers come up with something new, in fact, this is just an all-in-one chip integrates all the interfaces, that is as long as it is the same chip program TV with the underlying program is the same There is no uniqueness in the slightest.
As for the image processing solutions in the TV ARM chip, I will also give you an analogy. It is like a smart phone talking about HIFI. It is just like playing a stand-alone game. In some aspects, it is still incompetent. Although it can meet the needs of simple image processing, but absolutely not to force. What really deserves to show off is the independent quality engine, excellent algorithms, and a powerful database. And these are often things that require the company to spend a lot of money on its operations. There are very few people who have the ability to make great achievements.
A truly capable vendor needs to collect a large amount of front-end video material to form a database to serve the back-end image processing chip. With different materials, corresponding image processing algorithms can be created based on the information of large databases. For example, different clarity, different streams, different shades, different shades of video, how to find the corresponding algorithm from the database to optimize? And how do you get this algorithm? If you do not fully understand the hardware and content is impossible to do, can only buy a unified solution, this TV image processing is no soul, the popular term is the combination of hardware and software can only be a bad idea.
When it comes to quality, I can't help but want to talk about light control. As a liquid crystal television that requires a backlight for image display, light control and picture quality cannot be separated. When internet companies use jerky terms to emphasize picture quality, light control performance seems to be rarely mentioned. As TVs become thinner and thinner, there are fewer and fewer TVs with direct backlighting, although this technology has better light control performance. The edge-type backlight has always had uneven backlight problems, but LCD TVs have to be adopted in pursuit of ultra-thin, let alone it is also cheap. This has led to a situation where it is difficult to achieve the best of both worlds. The common solution now is to start working on the light guide board to solve the problem of non-uniform lighting. Therefore, the “We have adopted advanced technology light guide plates to increase the light efficiencyâ€. The difficulty needed for these changes is not great. Difficult local lighting controls and dynamic backlighting are difficult to see on Internet TV.
Summary: The smart TV chip is more than just the chip that supports the smart operating system. More functional stacks are ultimately presented through screens. An excellent image processing engine is the root of television, but a unified solution is not worth exaggerating.
These concepts are all fermenting
Wide viewing angle. A look at some of the panel types of Internet TV makers, and the IPS panels are basically used to promote them. As for the concept of wide viewing angle, it was originally a technical feature of the IPS screen, which started from about seventy eight years ago. IPS wide viewing angles should be contrasted with TN panels and VA panels, and the televisions produced today rarely use these two types of panels. These concepts are repeatedly boring.
X milliseconds dynamic response. This technology can be said with the previous MEMC, dynamic response can be understood as the refresh rate in the era of CRT, and MEMC is to fill the picture loss of the low-quality chip source on the high refresh rate device. The high-speed dynamic response I think is the necessary technology of TV, and the dynamic response time of most LCD TVs is between 8ms and 2ms at present.
Dynamic contrast. If manufacturers advertise that the dynamic contrast of a TV reaches 10,000:1, do you think it is very high? Actually, there are still several hundred million:1. The concept of dynamic contrast is really a bit metaphysical, and the screen is the brightest and darkest contrast. In order to achieve considerable data, manufacturers can often take many methods to improve the contrast, such as adjusting the maximum brightness, coupled with the differences in measurement methods, the results obtained are also very different.
XX color LCD panel. This technique is called color depth technology and the unit is bit. The one-billion-color LCD panel that we often listen to is actually saying that the color depth of this panel has reached 10 bits. The larger the unit value, the more natural and smooth the transition between levels. Of course, this is not the exclusive technology of anyone, and 8 to 10 bit color depth technology is used on most display devices. So when you see the promotion of this "more than a billion color LCD panel", don't be surprised.
4K ultra high definition UHD technology. I heard that China is the country with the highest 4K TV acceptance rate. The people of the country are not immune to the celebratory propaganda of TV manufacturers. There are many 4K TVs on the market. When UHD is used as a shield, it is simply a guilty conscience. UHD was originally the abbreviation of the Ultra HD standard (4K physical resolution). It's okay to hang on and say that this TV has nothing but high resolution.
Summary: It is not an easy task to think that it is not easy to be fooled by science and technology circles. Every day, you come up with so many bizarre things. Maintaining a realistic and objective attitude requires a lot of brain knowledge, and often in this brain supplement process. It has embarked on a brainwashed path of no return. The Internet TV manufacturers are scrambling for the tricks of the screen display and the concept of the picture quality engine. Everyone should be aware that most of the so-called black technologies are basic technologies that other traditional TV manufacturers have used for years. Of course, one cent is a eternal truth, and the cost-effectiveness of Internet TV is not to be done at a loss. They put more eyes on the Internet ecology, and display technology is not a matter of overnight. As the core of television, they can only avoid being light. As consumers, the only way to avoid the Internet's brainwashing is to remain skeptical and inquisitive.
