Ultra-wideband technology and the development of 4K ultra-high-definition
High-resolution replacing low-resolution is the trend in the display field in the past. In view of this, most people believe that 4K Ultra HD will replace HD as the next-generation mainstream display standard. However, due to the imperfect industrial chain in the budding period of 4K, the development of 4K has been plagued by problems such as shortage of film sources, imperfect standards, poor transmission channels, storage difficulties, and high prices. People have also questioned the development of 4K because of these problems, worrying that 4K is difficult to overcome these difficulties and will eventually become a bubble in the electronics field. However, these problems have been gradually improved with the efforts of many manufacturers, such as the transmission channel problem that has seriously affected the popularization of 4K. This problem has been perfectly solved technically after Huawei launched the ultra-wideband. Lubricant that promotes the maturity of the 4K industry chain To watch 4K videos online smoothly, the network bandwidth is required to be at least 20Mbps, and for high-quality 8K TVs, a bandwidth of more than 100Mbps is required. The bandwidth of ultra-wideband is 20Mbps-1000Mbps, so there is no pressure to conduct 4K and even higher-definition video on-demand online under ultra-wideband. In the field of mass entertainment that relies heavily on transmission channels, the emergence of ultra-broadband can make people lose the sigh of 'you can't enjoy 4K video even if you buy a 4K TV.' Although previous methods such as 4K set-top boxes and 4K exclusive channels can also cope with transmission problems, the 'whatever you want' that UWB can achieve is a huge charm that they cannot have. The professional audio-visual field mainly focuses on the 4K ultra-high resolution display function, which is not very sensitive to the transmission channel, but the emergence of ultra-wideband can make the solution more flexible. For example, after UWB is put into use, end-to-end UHD medical can effectively integrate well-known doctors in various places to analyze pathology and make timely treatment plans, reducing the damage caused by loss of details and propagation delay. Of course, it also allows the effective combination of ultra-high-definition display control system and cloud technology to create a system that is highly integrated, intelligent, and more in line with the new development of society. 4K signal transmission encounters ultra-wideband, just like the 4K industry chain is dripping with lubricant, which organically connects all links of the industry chain. The 4K industry chain still lacks a 'dongfeng'. At present, the 4K signal collection terminal, display terminal and standards have been relatively complete. The film source problem has become no longer as Amazon announced that all homemade dramas will be filmed in 4K and LeTV TV has begun to enrich 4K film sources. So sharp. In the field of audio and video signal processing that needs to closely cooperate with 4K signal acquisition terminals and 4K signal display terminals, 4K audio and video signal processing manufacturers represented by ATER have also emerged. The 4K signal transmission problem that plagued most people also disappeared after Huawei's ultra-wideband technology came out. At first glance, the factors for the popularity of 4K seem to already exist, but why hasn't 4K been thoroughly popularized so far? As we all know, after the emergence of problem-solving methods, manpower and material resources are needed to deal with the objective environment to implement them in order to solve the problem. On this issue, as Ding Yun, President of Huawei Products and Solutions, said, we still owe a “dongfeng”. The popularization of 4K is inseparable from the joint efforts of the country, society and the majority of users, and the enthusiasm of the three parties is required to blow this 'East Wind' together. The conclusion is that '4K is unstoppable.' Through the above, we can clearly see the continuous discovery of problems in the development of 4K, and there are continuous related policies and companies willing to solve these problems. Companies continue to promote the development of 4K in the process of their own efforts and mutual cooperation. For example, at the Huawei Global Ultra-Broadband Summit Forum, Huawei’s professional partners such as ATER and Yingtianxia jointly created a 4K large-screen fusion system that can 'see' the ultra-broadband style, and let the world see the 4K industry under the popularization of 4K. The epitome of the chain. Ultra-wideband is the heartbeat of the entire 4K industry chain. Once all of them are put into use, 4K will be able to quickly penetrate into all fields. Moreover, according to the Zhongguancun online survey, most users are willing to try 4K products at reasonable prices. Then, as technology and policies continue to mature, 4K has no reason to fold its wings. Finally, we still need some time to continue to pay attention to the development of ultra-broadband and 4K industry chain, to jointly witness that the rise of 4K is not a bubble. 2014 is the first year of 4K, and I believe 2016 will be the year of its rise.
