Under the "Internet +" boom, the development of smart homes has heated up dramatically. Smart TV, as an important part of smart homes, has also become the core of smart home storms.
According to a recent report by market research institute IHS Markit, as the most intuitive picture quality of TV, the proportion of 4K TV shipments has increased year by year, but in the overall color TV industry, 4K TV still fails to form momentum, and the agency estimates In 2018, the 8K LCD TV will be strong, and the 70-inch model will be the main sales force.
More advanced than the agency's forecast is that since the AWE2017 show this year, "8K" has become one of the hottest keywords in the color TV industry. Recently, the world's leading home appliance brand Sharp released news that the first consumer-grade 8K TV will be released at the end of August.
According to public information, 8K technology can achieve a resolution of 7680 × 4320 pixel size, that is, 7680 effective pixel points in the horizontal direction, 4320 effective pixel points in the vertical, the most recent 4K, only a quarter of 8K resolution . It can be seen that 8K can bring the ultimate picture quality experience, and the delicateness of the picture is unparalleled.
However, the market is generally worried that 8K TV can successfully achieve cornering overtaking when 4K TV fails to reach the trend. At the same time, in the era of smart home in the Internet of Things, can 8K TVs that have made major breakthroughs in display technology truly enter the smart home environment and become the big screen core of the family IoT?
Current consumers have new demands for smart TVs. "The first is the content, whether there is continuous update and rich content on 8K TV; the second is the smart TV operating system, based on the image data opened by 8K display technology," said Bao Wei, secretary general of China Intelligent Multimedia Terminal Technology Alliance. No updated and smarter operating system to communicate with the entire home environment; the third is the richness of the application, now not only watching TV, but also 'playing' TV, a lot of entertainment, education, information, services, Whether medical and other applications can be supported by 8K TV.
"At present, consumer demand for smart TV, in the home appliance companies chasing 8K TV, did not see the relevant support information." Bao Wei worried that 8K technology will become the gimmick of some home appliance companies in the competition, And consumers don't bring real benefits and changes in smart home life.
In fact, whether it is smart home or family content ecology, it is inseparable from the interactive system of smart TV. "If you think of smart home as a system, smart hardware products of large and small size are an accessory in the system. Finally, you should link the big screen to form a smart home system with human-computer interaction experience." Yao Xinwei, an associate professor at Zhejiang University of Technology, believes that As the protagonist of the living room and an important display terminal in the smart home, TV's natural advantages make it an interactive center, a control center, a play center and a storage center in a smart home.
“Technology leadership does not mean consumption leadership.†Dr. Tian Renhe from the Institute of Electronics, Chinese Academy of Sciences said that 8K technology has very strict hard standards, 7680×4320 progressive scan resolution, 22.2 channels and naked eye 3D display technology require the overall industry chain to be improved. However, there is no officially heard which manufacturer has the 8K technology industry chain.
Dr. Tian Renhe believes that in addition to the upstream LCD panel to the after-sales maintenance complete industrial chain, 8k technology enters the consumer, still faces the lack of 8K photographic equipment, and the hardware barrier of the processor is not up to standard. 8K technology to image processor Other TV components have put forward higher requirements." He said that the current mainstream image processor must redesign the image processor to avoid the problems of high heat and huge data processing. In addition, there are network broadband transmission requirements and storage problems. The current ordinary electrical signals and broadband cannot smoothly view 4K content. If you want to watch 8K content, you must carry out a huge signal broadband transmission transformation project. At the same time, "recording 20K 8K Ultra HD video will take up 4TB of storage space."
"Even if the 8K technology hardware industry chain can be perfected, but the lack of 8K corresponding content, is the biggest obstacle for 8K TV can not enter the consumer." China Electronics Technology Standardization Institute related expert report, the current 4K ultra HD film Source content is still scarce, so 8K content beyond 4K technology is even more scarce. Without content, the terminal appears useless.
Dr. Tian Renhe also believes this judgment. In his view, the real value of 8K technology is to open up the image data, and the interconnection of the home environment makes the image data more valuable. However, at present, other elements of the smart home environment interconnected with 8K TV in the future, whether the image reaches the 8K standard, and the smooth interconnection of 8K TV has become the biggest test of 8K entering the era of intelligent home in the Internet of Things. "This requires 8K." A variety of signal transmission systems such as the Internet of Things, the Internet, the traditional communication network, and the sensor network behind the TV have reached consensus."
"In the era of intelligent home of the Internet of Things, a good smart TV must have excellent hardware, easy-to-use software, and rich content." An expert from the China Household Electrical Appliances Association said that the prospect of 8K technology construction is quite attractive. People, but for consumers, they should polish their eyes and see the essence through the concept of technology. They must look at the quality of the TV as the hardware experience of the TV itself, but also the content and interconnection of the Internet of Things era. The comprehensive experience is the king. After all, 8K TV can't be defined as “one TVâ€, but an ecosystem of 8K TV as the smart home environment of the home Internet of Things hub.
