Promote 4K Application Development 8K Technology

Recently, at the 2nd China Electronics Information Expo, the 98-inch 8K×4K ultra-high-definition display screen displayed by BOE, a leading company in the field of semiconductor display in China, was enthusiastically sought after by the audience. At the same time, it attracted the enthusiasm of domestic and foreign counterparts. It is reported that this is currently the world's largest size 8K × 4K display, its resolution up to 7680 × 4320, the display effect is 4K 4 times, is more than 16 times the current mainstream FHD, the picture quality is extremely delicate, can restore the maximum degree of real Color, and can cover the entire visual field of the human eye, giving viewers an unparalleled sense of presence.

In recent years, continuously improving the resolution of display screens seems to be a trend. Whether it is a large-screen television or a smart terminal in mobile screens of small and medium screens, high resolution has become an indicator actively promoted by panel and terminal companies, from HD (720×1280). ) To FHD (1080 × 1920), and from 2K (1152 × 2048) to 4K (2160 × 4096), 8K is now a hot target in the industry. However, whether high-resolution display is really necessary or not, whether the business model of ultra-high definition era will be innovated and evolved when the key chains such as content and standards are not yet perfected? Judgments and opinions.

Judging from the market demand, the leap in quality brought by 4K is unprecedented, and a quality video viewing experience naturally will bring a broad market prospect. In the basic balance of panel production capacity today, panel companies not only demonstrate their own technical strength through the introduction of 4K panels, but also can digest production capacity and increase product profits. TV companies are favored in the 3D, smart TV boom has gradually receded, after another one to make money to make money selling point.

In terms of content availability, although the accumulation of 4K content is still in its infancy compared with ordinary HD video, it is worth noting that almost all successful video service providers have begun to focus on 4K content. The domestic LeTV hand Zhang Yimou, using IMAX 4K technology to shoot new films; the United States began shooting with 4K cameras in 2013, at least two digital levels of native 4K content; as a technology-controlled Japanese, is even more High-tech applications never lag behind. NHK TV announced that it will start broadcasting 4K TV programs in July this year. The first broadcast will be the World Cup Final in Rio de Janeiro.

Judging from the degree of technical cooperation, 4K video storage and transmission is the fundamental guarantee for 4K viewing. By creating a new generation of video coding standard H.265, not only can compress the size but also support 4K video, clearing the obstacles for the transmission of 4K video over the Internet. On the other hand, the 2K to 4K chip and algorithm solution has basically penetrated into the 4K televisions of major TV manufacturers, consumers can avoid awkward 2K content viewing on a 4K screen through interpolation algorithms, and “native content insufficiency algorithm supplementation” can be considered unsatisfactory.

Judging from the business model, the legitimacy and richness of content will ultimately determine the success of the business model. At present, video service costs are mainly digested by two methods. First, content services and equipment are bundled and sold. The rapid impact that LeTV, which was also exhibited at CITE 2014, brought to traditional television in 2013 is based on this model. The LeTV stock price itself has also become a successful interpretation of Internet thinking; the second is the operator-led packaging model. Operators provide bandwidth, video providers and television companies integrate content, and bundle sales of televisions, broadband services, and video subscription services to consumers through broadband bundled sales. Mature channels and stable structure have brought a good foundation for the development of this model.

From the above analysis, it can be seen that, with the efforts of various parties such as manufacturing, content, storage, and dissemination, the 4K industry chain is still immature and reluctant, but it has basically been completed. It is only a matter of time before flying into the homes of ordinary people. Next, 8K large-scale civilian use still has a long way to go. As the old saying puts it, “taking the best of them”, doing 8K dreams in 4K rivers and lakes, maybe it is to promote 4K applications and develop 8K technologies. The best way to go ahead.
